PART I

ITEM 1. BUSINESS

DESCRIPTION OF BUSINESS

Southwest Airlines Co. ("Southwest") is a major domestic airline that
provides primarily shorthaul, high-frequency, point-to-point, low-fare service.
Southwest was incorporated in Texas and commenced Customer Service on June 18,
1971 with three Boeing 737 aircraft serving three Texas cities - Dallas,
Houston, and San Antonio.

At yearend 2000, Southwest operated 344 Boeing 737 aircraft and provided
service to 58 airports in 57 cities in 29 states throughout the United States.
Southwest commenced service to Albany, New York and Buffalo, New York in May and
October 2000, respectively, and to West Palm Beach, Florida in January 2001.
Southwest will discontinue service to San Francisco International Airport in
March 2001, relocating the 14 flights per day from that airport to Oakland and
San Jose, California.

Based on data for second quarter 2000 (the latest available data),
Southwest Airlines is the 4th largest carrier in the United States based on
domestic passengers boarded and the largest based on scheduled domestic
departures.

The business of the Company is somewhat seasonal. Quarterly operating
income and, to a lesser extent, revenues tend to be lower in the first quarter
(January 1 - March 31).

FUEL

The cost of fuel is an item having significant impact on the Company's
operating results. The Company's average cost of jet fuel over the past five
years was as follows:



COST AVERAGE PRICE PERCENT OF
YEAR (Millions) PER GALLON OPERATING EXPENSES
---- ---------- ------------- ------------------

1996 $484.7 $.65 15.9%
1997 $495.0 $.62 15.0%
1998 $388.3 $.46 11.2%
1999 $492.4 $.53 12.5%
2000 $804.4 $.79 17.4%


See "Management's Discussion and Analysis of Financial Condition and
Results of Operations" for a discussion of Southwest's fuel hedging activities.

REGULATION

Economic. The Dallas Love Field section of the International Air
Transportation Competition Act of 1979, as amended in 1997 (commonly known as
the "Wright Amendment"), as it affects Southwest's scheduled service, provides
that no common carrier may provide scheduled passenger air transportation for
compensation between Love Field and one or more points outside Texas, except
that an air carrier may transport individuals by air on a flight between Love
Field and one or more points within the states of Alabama, Arkansas, Kansas,
Louisiana, Mississippi, New Mexico, Oklahoma, and Texas if (a) "such air


3


carrier does not offer or provide any through service or ticketing with another
air carrier" and (b) "such air carrier does not offer for sale transportation to
or from, and the flight or aircraft does not serve, any point which is outside
any such states." The Wright Amendment does not restrict flights operated with
aircraft having 56 or fewer passenger seats. Southwest does not interline or
offer joint fares with any other air carrier. The Wright Amendment does not
restrict Southwest's intrastate Texas flights or its air service from points
other than Love Field.

The Department of Transportation ("DOT") has significant regulatory
jurisdiction over passenger airlines. Unless exempted, no air carrier may
furnish air transportation over any route without a DOT certificate of
authorization, which does not confer either exclusive or proprietary rights. The
Company's certificates are unlimited in duration and permit the Company to
operate among any points within the United States, its territories and
possessions, except as limited by the Wright Amendment, as do the certificates
of all other U.S. carriers. DOT may revoke such certificates, in whole or in
part, for intentional failure to comply with any provisions of subchapter IV of
the Federal Aviation Act of 1958, or any order, rule or regulation issued
thereunder or any term, condition or limitation of such certificate; provided
that, with respect to revocation, the certificate holder has first been advised
of the alleged violation and has been given a reasonable time to effect
compliance.

DOT prescribes uniform disclosure standards regarding terms and conditions
of carriage, and prescribes that terms incorporated into the Contract of
Carriage by reference are not binding upon passengers unless notice is given in
accordance with its regulations.

Safety. The Company is subject to the jurisdiction of the Federal Aviation
Administration ("FAA") with respect to its aircraft maintenance and operations,
including equipment, ground facilities, dispatch, communications, flight
training personnel, and other matters affecting air safety. To ensure compliance
with its regulations, the FAA requires airlines to obtain operating,
airworthiness, and other certificates, which are subject to suspension or
revocation for cause. The Company has obtained such certificates. The FAA,
acting through its own powers or through the appropriate U. S. Attorney, also
has the power to bring proceedings for the imposition and collection of fines
for violation of the Federal Air Regulations.

The Company is subject to various other federal, state, and local laws and
regulations relating to occupational safety and health, including Occupational
Safety and Health Administration (OSHA) and Food and Drug Administration (FDA)
regulations.

Environmental. Certain airports, including San Diego, Burbank, and Orange
County, have established airport restrictions to limit noise, including
restrictions on aircraft types to be used and limits on the number of hourly or
daily operations or the time of such operations. In some instances, these
restrictions have caused curtailments in service or increases in operating
costs, and such restrictions could limit the ability of Southwest to expand its
operations at the affected airports. Local authorities at other airports may
consider adopting similar noise regulations, but such regulations are subject to
the provisions of the Airport Noise and Capacity Act of 1990 and regulations
promulgated thereunder.

Operations at John Wayne Airport, Orange County, California, are governed
by the Airport's Phase 2 Commercial Airline Access Plan and Regulation (the
"Plan"). Pursuant to the Plan, each airline is allocated total annual seat
capacity to be operated at the airport, subject to renewal/reallocation on an
annual basis. Service at this airport may be adjusted annually to meet these
requirements.

The Company is subject to various other federal, state, and local laws and
regulations relating to the protection of the environment, including the
discharge or disposal of materials such as chemicals, hazardous waste, and
aircraft deicing fluid. Potential future regulatory developments pertaining to
such things as control of engine exhaust emissions from ground support equipment
and prevention of leaks from


2
4


underground aircraft fueling systems could increase operating costs in the
airline industry. The Company does not believe, however, that such environmental
regulatory developments will have a material impact on the Company's capital
expenditures or otherwise adversely effect its operations, operating costs, or
competitive position. Additionally, in conjunction with airport authorities,
other airlines, and state and local environmental regulatory agencies, the
Company is undertaking voluntary investigation or remediation of soil or
groundwater contamination at several airport sites. While the full extent of any
contamination at such sites and the parties responsible for such contamination
have not been determined, the Company does not believe that any environmental
liability associated with such sites will have a material adverse effect on the
Company's operations, costs, or profitability.

Customer Service Commitment. During 1999, the airline transportation
industry faced possible legislation dealing with certain customer service
practices. As a compromise with Congress, the industry, working with the Air
Transport Association, responded by adopting and filing with the DOT written
plans disclosing how it would commit to improving performance. Southwest
Airlines formalized its dedication to Customer Satisfaction by adopting its
Customer Service Commitment, a comprehensive plan which embodies the Mission
Statement of Southwest Airlines: dedication to the highest quality of Customer
Service delivered with a sense of warmth, friendliness, individual pride, and
Company Spirit. The Customer Service Commitment can be reviewed by clicking on
"About SWA" at www.southwest.com. Congress is expected to monitor the effects of
the industry's plans, and there can be no assurance that legislation will not be
proposed in the future to regulate airline practices.

MARKETING AND COMPETITION

Southwest focuses principally on point-to-point, rather than
hub-and-spoke, service in shorthaul markets with frequent, conveniently timed
flights, and low fares. For example, Southwest's average aircraft trip length in
2000 was 492 miles with an average duration of approximately 1.5 hours. At
yearend, Southwest served approximately 306 one-way nonstop city pairs.

Southwest's point-to-point route system, as compared to hub-and-spoke,
provides for more direct nonstop routings for shorthaul customers and,
therefore, minimizes connections, delays, and total trip time. Southwest focuses
on nonstop, not connecting, traffic. As a result, approximately 77 percent of
the Company's Customers fly nonstop. In addition, Southwest serves many
conveniently-located satellite or downtown airports such as Dallas Love Field,
Houston Hobby, Chicago Midway, Baltimore-Washington International, Burbank,
Manchester, Oakland, San Jose, Providence, Ft. Lauderdale/Hollywood and Long
Island airports, which are typically less congested than other airlines' hub
airports and enhance the Company's ability to sustain high Employee productivity
and reliable ontime performance. This operating strategy also permits the
Company to achieve high asset utilization. Aircraft are scheduled to minimize
the amount of time the aircraft is at the gate, currently approximately 25
minutes, thereby reducing the number of aircraft and gate facilities that would
otherwise be required. Southwest does not interline with other airlines, nor
have any commuter feeder relationships.

Southwest employs a very simple fare structure, featuring low,
unrestricted, unlimited, everyday coach fares. The Company operates only one
aircraft type, the Boeing 737, which simplifies scheduling, maintenance, flight
operations, and training activities.

In January 1995, Southwest was the first major airline to introduce a
Ticketless travel option, eliminating the need to print a paper ticket
altogether. Southwest also entered into an arrangement with SABRE, the computer
reservation system in which Southwest has historically participated to a limited
extent, providing for ticketing and automated booking on Southwest in a very
cost-effective manner. In 1996, Southwest began offering Ticketless travel
through the Company's home page on the Internet's World Wide Web at
http://www.southwest.com. At the end of 2000, approximately 80% of Southwest's


3
5


Customers chose the Ticketless travel option. In December 2000 approximately 39%
of Southwest's passenger revenues came through its Internet site, which has
become a vital part of the Company's distribution strategy.

The airline industry is highly competitive as to fares, frequent flyer
benefits, routes, and service, and some carriers competing with the Company have
greater financial resources, larger fleets, and wider name recognition. Several
of the Company's larger competitors offer low-cost, shorthaul service in markets
served by the Company, which represents a more direct threat in Southwest's
market niche. Certain major United States airlines have established marketing
alliances with each other, including Northwest Airlines/Continental Airlines,
American Airlines/Alaska Airlines, and Continental Airlines/America West
Airlines. During 2000, two of our competitors, UAL Corporation and USAirways,
Inc., entered into a merger agreement and in January 2001, AMR Corp. announced a
plan to purchase the assets of Trans World Airlines, along with certain assets
of USAirways, Inc. If those acquisitions are concluded, competition in the
airline industry could be significantly altered. Profit levels in the air
transport industry are highly sensitive to changes in operating and capital
costs and the extent to which competitors match an airline's fares and services.
The profitability of a carrier in the airline industry is also impacted by
general economic trends.

The Company is also subject to varying degrees of competition from surface
transportation in its shorthaul markets, particularly the private automobile. In
shorthaul air services that compete with surface transportation, price is a
competitive factor, but frequency and convenience of scheduling, facilities,
transportation safety, and Customer Service may be of equal or greater
importance to many passengers.

INSURANCE

The Company carries insurance of types customary in the airline industry
and at amounts deemed adequate to protect the Company and its property and to
comply both with federal regulations and certain of the Company's credit and
lease agreements. The policies principally provide coverage for public and
passenger liability, property damage, cargo and baggage liability, loss or
damage to aircraft, engines, and spare parts, and workers' compensation.

FREQUENT FLYER AWARDS

Southwest's frequent flyer program, Rapid Rewards, is based on trips flown
rather than mileage. Rapid Rewards Customers earn a flight segment credit for
each one-way trip flown or two credits for each round trip flown. Rapid Rewards
Customers can also receive flight segment credits by using the services of
non-airline partners, which include credit card partners, a telephone company,
car rental agencies, hotels, and the Southwest Airlines First USA (R) Visa card.
Rapid Rewards offers two types of travel awards. The Rapid Rewards Award Ticket
("Award Ticket") offers one free roundtrip travel award to any Southwest
destination after the accumulation of 16 flight segment credits within a
consecutive twelve-month period. The Rapid Rewards Companion Pass ("Companion
Pass") is granted after flying 50 roundtrips (or 100 one- way trips) on
Southwest within a consecutive twelve-month period. The Companion Pass offers
unlimited free roundtrip travel to any Southwest destination for a companion of
the qualifying Rapid Rewards member. In order for the companion to use this
pass, the Rapid Rewards member must purchase a ticket or use an Award Ticket.
Additionally, the Rapid Rewards member and companion must travel together on the
same flight.

Trips flown are valid for flight segment credits toward Award Tickets and
Companion Passes for twelve months only; Award Tickets and Companion Passes are
automatically generated when earned by the Customer rather than allowing the
Customer to bank credits indefinitely and Award Tickets and Companion Passes are
valid for one year with an automatic expiration date. "Black out" dates apply
during peak holiday periods.


4
6


The Company also sells flight segment credits to business partners
including credit card companies, phone companies, hotels, and car rental
agencies. These credits may be redeemed for Award Tickets having the same
program characteristics as those earned by flying.

Customers redeemed approximately 1,571,000, 1,248,000 and 927,000 Award
Tickets and flights on Companion Passes during 2000, 1999 and 1998 respectively.
The amount of free travel award usage as a percentage of total Southwest revenue
passengers carried was 4.9 percent in 2000, 4.3 percent in 1999 and 3.5 percent
in 1998. The number of Award Tickets outstanding at December 31, 2000 and 1999
was approximately 985,000 and 846,000, respectively. These numbers do not
include partially earned Award Tickets. The Company currently does not have a
system to accurately estimate partially earned Award Tickets. However, these
partially earned Award Tickets may equal 75 percent or more of the current
outstanding Award Tickets. Since the inception of Rapid Rewards in 1987,
approximately 14 percent of all Award Tickets have expired without being used.
The number of Companion Passes for Southwest outstanding at December 31, 2000
and 1999 was approximately 41,000 and 32,000, respectively. The Company
currently estimates that 3 to 4 trips will be redeemed per outstanding Companion
Pass. The Company's frequent flyer program has not had a material impact on its
results of operations or financial condition.

The Company accounts for its frequent flyer program obligations by
recording a liability for the estimated incremental cost of flight awards the
Company expects to be redeemed (except for flight segment credits sold to
business partners). This method recognizes an average incremental cost to
provide roundtrip transportation to one additional passenger. The estimated
incremental cost includes direct passenger costs such as fuel, food and other
operational costs, but does not include any contribution to overhead or profit.
The incremental cost is accrued at the time an award is earned and revenue is
subsequently recognized, at the amount accrued, when the free travel award is
used. For flight segment credits sold to business partners prior to January 1,
2000 revenue was recognized when the credits were sold. Beginning January 1,
2000, revenue from the sale of flight segment credits and associated with future
travel is deferred and recognized when the ultimate free travel award is flown
or the credits expire unused. Accordingly, Southwest does not accrue incremental
cost for the expected redemption of free travel awards for credits sold to
business partners. The liability for free travel awards earned but not used at
December 31, 2000 and 1999 was not material.

EMPLOYEES

At December 31, 2000, Southwest had 29,274 active employees, consisting of
9,610 flight, 1,414 maintenance, 14,560 ground customer and fleet service and
3,690 management, accounting, marketing, and clerical personnel.

Southwest has ten collective bargaining agreements covering approximately
83 percent of its employees. The following table sets forth the Company's

ITEM 2. PROPERTIES

AIRCRAFT

Southwest operated a total of 344 Boeing 737 aircraft as of December 31,
2000, of which 94 and seven were under operating and capital leases,
respectively. The remaining 243 aircraft were owned.

Southwest was the launch customer for the Boeing 737-700 aircraft, one of
the newest generation of the Boeing 737 aircraft type. The first 737-700
aircraft was delivered in December 1997 and entered revenue service in January
1998. At December 31, 2000, Southwest had 92 Boeing 737-700 aircraft in service.

In total, at December 31, 2000, the Company had firm orders and options to
purchase Boeing 737 Aircraft as follows:

The Company currently intends to retire its fleet of 33 Boeing 737-200
aircraft over the next five years.

The average age of the Company's fleet at December 31, 2000 was 8.2 years.

GROUND FACILITIES AND SERVICES

Southwest leases terminal passenger service facilities at each of the
airports it serves to which it has added various leasehold improvements. The
Company leases land on a long-term basis for its maintenance centers located at
Dallas Love Field, Houston Hobby, and Phoenix Sky Harbor, its training center
near Love Field, which houses five 737 simulators, and its corporate
headquarters, also located near Love Field. The maintenance, training center,
and corporate headquarters buildings on these sites were built and are owned by
Southwest. At December 31, 2000, the Company operated nine reservation centers.
The reservation centers located in Little Rock, Arkansas; Chicago, Illinois;
Albuquerque, New Mexico; and Oklahoma City, Oklahoma occupy leased space. The
Company owns its Dallas, Texas; Houston, Texas; Phoenix, Arizona; Salt Lake
City, Utah; and San Antonio, Texas reservation centers.

The Company performs substantially all line maintenance on its aircraft
and provides ground support services at most of the airports it serves. However,
the Company has arrangements with certain aircraft maintenance firms for major
component inspections and repairs for its airframes and engines, which comprise
the majority of the annual maintenance costs.

ITEM 3. LEGAL PROCEEDINGS

The Company received a statutory notice of deficiency from the Internal
Revenue Service (the "IRS") in which the IRS proposed to defer deductions
claimed by the Company on its federal income tax returns for the taxable years
1989 through 1991 for the costs of certain aircraft inspection and maintenance
procedures. In defense of the notice of deficiency, the Company filed a petition
in the United States Tax Court on October 30, 1997, seeking a determination that
the IRS erred in disallowing the deductions claimed by the Company and that
there is no deficiency in the Company's tax liability for the taxable years in
issue. The notice of deficiency received by the Company stemmed from an
industry-wide challenge by the IRS of the long standing practice of currently
expensing aircraft inspection and maintenance costs, and similar adjustments
have been proposed by the IRS to the tax returns of numerous other members of
the airline industry. In response to this challenge, the Air Transport
Association of America, the airline industry's trade association, since late
1996 has been in discussions with the Treasury Department and the national
office of the IRS regarding the issuance of unpublished guidance confirming the
industry's practice of expensing the subject inspection and maintenance costs.
On December 21, 2000, the national office of the IRS published a revenue ruling
in which it concluded that aircraft inspection and maintenance substantially the
same as that in issue in the Company's Tax Court suit is currently deductible as
an ordinary and necessary business expense. Counsel for the company and the IRS
soon will engage in discussions in an attempt to resolve the controversy in
conformity with the IRS' revenue ruling and without the necessity of further
litigation. Management believes that the final resolution of this controversy
will not have a materially adverse effect upon the financial condition or
results of operations of the Company. This forward-looking statement is based on
management's current understanding of the relevant law and facts; it is subject
to various contingencies including the views of legal counsel, changes in the
IRS' position, the potential cost and risk associated with litigation, and the
actions of the IRS, judges and juries.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATION

YEAR IN REVIEW

Southwest posted a profit for the 28th consecutive year and a record annual
profit for the ninth consecutive year. This excellent financial performance was
achieved despite the highest jet fuel prices since 1990. Operating revenues and
operating income were the highest in the Company's history. Southwest's margin
performance was the best in 20 years with an operating margin of 18.1 percent
and net profit margin (before the cumulative effect of a change in accounting
principle) of 11.1 percent. The Company's revenue growth and continued strong
demand for our product were evident through our achievement of a record 2000
load factor (revenue passenger miles divided by available seat miles) of 70.5
percent and record load factors in three of the four calendar quarters of 2000.

At the end of 2000, Southwest served 57 cities in 29 states. We continued our
East Coast expansion in 2000, adding service to Albany, New York, in May 2000,
and Buffalo, New York, in October 2000 and have been very pleased with the
results in each of these new Southwest cities. The Company recently announced
plans to commence service to West Palm Beach, Florida in January 2001 and will
begin service to at least one other new city in 2001. In addition, we plan to
continue to add flights and additional frequencies between cities we already
serve.

Capacity is expected to grow approximately 11 percent in 2001 with the net
addition of 21 aircraft. The Company will acquire 25 new Boeing 737-700s
scheduled for delivery during the year and plans to retire four of the Company's
older 737-200s.

RESULTS OF OPERATIONS

2000 COMPARED WITH 1999 The Company's consolidated income for 2000 before the
cumulative effect of a change in accounting principle was $625.2 million ($1.18
per share, diluted), an increase of 31.8 percent. The cumulative change in
accounting principle, related to the adoption of SEC Staff Accounting Bulletin
No. 101, was $22.1 million, net of taxes of $14.0 million (see Note 2 to the
Consolidated Financial Statements). Net income, after the cumulative change in
accounting principle, was $603.1 million. Diluted net income per share, after
consideration of the accounting change, was $1.14 compared to $.89 in 1999.
Operating income was $1,021.1 million, an increase of 30.7 percent compared to
1999.

OPERATING REVENUES Consolidated operating revenues increased 19.3 percent
primarily due to a 19.8 percent increase in passenger revenues. The increase in
passenger revenues primarily resulted from the Company's increased capacity,
strong demand for commercial air travel, and excellent marketing and revenue
management. The Company experienced a 10.7 percent increase in revenue
passengers carried, a 15.7 percent increase in revenue passenger miles (RPMs),
and a 3.6 percent increase in passenger revenue yield per RPM (passenger yield).
The increase in passenger yield was primarily due to an 8.2 percent increase in
average passenger fare, partially offset by a 4.6


11
13


percent increase in average length of passenger haul. The increase in average
passenger fare was primarily due to modest fare increases taken combined with a
higher mix of full-fare passengers.

The increase in RPMs exceeded a 13.3 percent increase in available seat miles
(ASMs) resulting in a load factor of 70.5 percent, or 1.5 points above the prior
year. The increase in ASMs resulted primarily from the net addition of 32
aircraft during the year. Thus far, load factors in January 2001 have exceeded
those experienced in January 2000. Bookings for February and March are also good
and we presently anticipate positive year-over-year unit revenue (operating
revenues divided by ASMs) comparisons again in first quarter 2001, although we
do not expect to match the fourth quarter 2000 year-over-year unit revenue
growth rate of 7.8 percent. (The immediately preceding two sentences are
forward-looking statements, which involve uncertainties that could result in
actual results differing materially from expected results. Some significant
factors include, but may not be limited to, competitive pressure such as fare
sales and capacity changes by other carriers, general economic conditions,
operational disruptions as a result of bad weather, industry consolidation, air
traffic control related difficulties, the impact of labor issues, and variations
in advance booking trends.)

Freight revenues increased 7.5 percent primarily due to an increase in capacity.
Other revenues, which consist primarily of charter revenues, increased 1.2
percent. This increase was less than the Company's increase in capacity
primarily due to the Company's decision to utilize more of its aircraft to
satisfy the strong demand for scheduled service and, therefore, make fewer
aircraft available for charters.

OPERATING EXPENSES Consolidated operating expenses for 2000 increased 17.1
percent, compared to the 13.3 percent increase in capacity. Operating expenses
per ASM increased 3.3 percent to $.0773, compared to $.0748 in 1999, primarily
due to an increase in average jet fuel prices. The average fuel cost per gallon
in 2000 was $.7869, which was the highest annual average fuel cost per gallon
experienced by the Company since 1984. Excluding fuel expense, operating
expenses per ASM decreased 2.6 percent.

Operating expenses per ASM for 2000 and 1999 were as follows:

==== ==== === ====


Salaries, wages, and benefits per ASM increased slightly, as increases in
productivity in several of the Company's operational areas were more than offset
by higher benefits costs, primarily workers' compensation expense, and increases
in average wage rates within certain workgroups.

The Company's Ramp, Operations, and Provisioning Agents are subject to an
agreement with the Transport Workers Union of America, (TWU), which became
amendable in December 1999. Southwest is currently in negotiations with TWU for
a new contract. The Company's Mechanics are subject to an agreement with the
International Brotherhood of Teamsters (the Teamsters), which becomes amendable
in August 2001.

Retirement plans expense per ASM increased 11.1 percent, primarily due to the
increase in Company earnings available for profitsharing.

Fuel and oil expense per ASM increased 44.1 percent, primarily due to a 49.3
percent increase in the average jet fuel cost per gallon. The average price per
gallon of jet fuel in 2000 was $.7869 compared to $.5271 in 1999, including the
effects of hedging activities. The Company's 2000 and 1999 average jet fuel
prices are net of approximately $113.5 million and $14.8 million in gains from
hedging activities, respectively. As detailed in Note 7 to the Consolidated
Financial Statements, the Company has hedges in place for the majority of its
anticipated fuel consumption in 2001 at prices below market prices as of
December 31, 2000. Including estimated hedging gains and considering current
market prices and the anticipated impact of the adoption of Statement of
Financial Accounting Standards No. 133 (SFAS 133) (see Recent Accounting
Developments in Note 1 to the Consolidated Financial Statements), we are
forecasting our first quarter 2001 average fuel price per gallon to be no higher
than first quarter 2000's average price per gallon of $.82. (The immediately
preceding sentence is a forward-looking statement which involves uncertainties
that could result in actual results differing materially from expected results.
Such uncertainties include, but may not be limited to, the largely unpredictable
levels of jet fuel prices and the effectiveness of the Company's hedges.)


13
15


Maintenance materials and repairs per ASM decreased 10.0 percent primarily
because of a decrease in engine maintenance expense for the Company's 737-200
aircraft fleet as 1999 was an unusually high period for engine maintenance on
these aircraft. The -200 engine repairs are expensed on a time and materials
basis. These engine repairs represented approximately 75 percent of the total
decrease, while a decrease in airframe inspections and repairs per ASM
represented the majority of the remaining total decrease. The decrease in
airframe inspections and repairs was primarily due to a greater amount of this
work being performed internally versus 1999, when a large portion of this type
of work was outsourced. Therefore, in 2000, a larger portion of the cost of
these repairs is reflected in salaries and wages. Currently, we do not expect a
significant increase in unit cost for maintenance materials and repairs in first
quarter 2001 versus first quarter 2000. (The immediately preceding sentence is a
forward-looking statement involving uncertainties that could result in actual
results differing materially from expected results. Such uncertainties include,
but may not be limited to, any unscheduled required aircraft airframe or engine
repairs and regulatory requirements.)

Agency commissions per ASM decreased 10.0 percent, primarily due to a decrease
in commissionable revenue. Approximately 31 percent of the Company's 2000
revenues were attributable to direct bookings through the Company's Internet
site compared to approximately 19 percent in the prior year. The increase in
Internet revenues contributed to the Company's percentage of commissionable
revenues decreasing from 34.6 percent in 1999 to 29.1 percent in 2000. The
Company recently announced a change in its commission rate policy. Beginning
January 1, 2001, the Company will decrease the commission it pays to travel
agents from ten percent to eight percent for ticketless bookings, and from ten
percent to five percent for paper ticket bookings. The Company will continue to
pay no commission on internet agency bookings. Based on the policy change, the
Company expects agency commissions to decrease on a per-ASM basis in 2001. (The
immediately preceding sentence is a forward-looking statement involving
uncertainties that could result in actual results differing materially from
expected results. Such uncertainties include, but may not be limited to, changes
in consumer ticket purchasing habits.)

Aircraft rentals decreased 13.2 percent primarily due to a lower percentage of
the aircraft fleet being leased. Approximately 27.3 percent of the Company's
aircraft were under operating lease at December 31, 2000, compared to 30.8
percent at December 31, 1999. Based on the Company's current new aircraft
delivery schedule and scheduled aircraft retirements for 2001, we expect a
decline in aircraft rental expense per ASM in 2001. (The immediately preceding
sentence is a forward-looking statement involving uncertainties that could
result in actual results differing materially from expected results. Such
uncertainties include, but may not be limited to, changes in the Company's
current schedule for purchase and/or retirement of aircraft.)

Landing fees and other rentals per ASM decreased 4.3 percent primarily as a
result of a decrease in landing fees per ASM of 6.7 percent, partially offset by
a slight increase in other rentals. Although landing fees declined on a per-ASM
basis, they were basically flat on a per-trip basis. The growth in ASMs exceeded
the trip growth primarily due to a 5.8 percent increase in stage length (the
average distance per aircraft trip flown).


14
16


Other operating expenses per ASM decreased 3.4 percent primarily due to
Company-wide cost reduction efforts. The Company also reduced its advertising
expense 9.5% per ASM, taking advantage of our national presence, increasing
brand awareness, and strong Customer demand.

OTHER "Other expenses (income)" included interest expense, capitalized interest,
interest income, and other gains and losses. Interest expense increased 29.1
percent due primarily to the Company's issuance of $256 million of long-term
debt in fourth quarter 1999. Capitalized interest decreased 11.9 percent
primarily as a result of lower 2000 progress payment balances for scheduled
future aircraft deliveries compared to 1999. Interest income increased 59.0
percent primarily due to higher invested cash balances and higher rates of
return. Other losses in 1999 resulted primarily from a write-down associated
with the consolidation of certain software development projects.

INCOME TAXES The provision for income taxes, as a percentage of income before
taxes, decreased slightly to 38.54 percent in 2000 from 38.68 percent in 1999.

1999 COMPARED WITH 1998 The Company's consolidated net income for 1999 was
$474.4 million ($.89 per share, diluted), as compared to the corresponding 1998
amount of $433.4 million ($.82 per share, diluted), an increase of 9.4 percent.
Operating income increased 14.3 percent to $781.6 million.

OPERATING REVENUES Consolidated operating revenues increased 13.7 percent
primarily due to a 13.8 percent increase in passenger revenues. The increase in
passenger revenues was primarily due to a 9.3 percent increase in revenue
passengers carried and a 16.1 percent increase in RPMs. The passenger yield
decreased 2.0 percent to $.1251 primarily due to an increase in average length
of passenger haul of 6.2 percent partially offset by a 4.1 percent increase in
average passenger fare.

The 16.1 percent increase in RPMs exceeded the 11.2 percent increase in ASMs,
resulting in an increase in load factor from 66.1 percent in 1998 to 69.0
percent in 1999. The 1999 ASM growth resulted from the net addition of 32
aircraft during the year.

Freight revenues increased 4.6 percent compared to 1998 primarily due to added
capacity and modest rate increases. Other revenues increased 26.2 percent
primarily due to an increase in charter revenue.

OPERATING EXPENSES Consolidated operating expenses increased 13.6 percent,
compared to the 11.2 percent increase in capacity. Operating expenses per ASM
increased 2.2 percent in 1999 primarily due to a 15.4 percent increase in
average jet fuel prices. Excluding fuel expense, operating expenses per ASM for
1999 increased .8 percent.

Salaries, wages, and benefits per ASM increased 1.7 percent in 1999. This
increase resulted primarily from increases in benefits costs, specifically
workers' compensation and health care expense.


15
17


Retirement plans expense per ASM increased slightly due to higher earnings
available for profitsharing.

Fuel and oil expenses per ASM increased 13.4 percent primarily due to a 15.4
percent increase in the average jet fuel cost per gallon. The average price paid
for jet fuel in 1999 was $.5271, including the effects of hedging activities,
compared to $.4567 in 1998. The Company's 1999 average jet fuel price is net of
approximately $14.8 million in gains from hedging activities. Hedging activities
in 1998 were not significant.

Maintenance materials and repairs expense per ASM increased 9.4 percent in 1999
compared to 1998. Routine heavy maintenance or airframe inspections and repairs
represented approximately 74 percent of the increase, while engine inspection
and repair costs represented approximately 25 percent of the increase. The
increase in airframe inspections and repairs was due primarily to a heavier
volume of routine airframe checks scheduled for 1999 versus 1998. Further, a
portion of the Company's scheduled airframe checks was outsourced in 1999 as the
volume of work exceeded the available internal headcount and facilities
necessary to perform such maintenance. In 1998, the Company performed all of
this type of routine heavy maintenance internally; thus, the majority of these
costs were reflected in salaries and wages. The increases in engine inspection
and repair costs were primarily related to the Company's 737-200 aircraft. The
Company's 737-200 aircraft engine inspections and repairs are performed on a
time and materials basis and are not covered by the Company's power-by-the-hour
engine maintenance contract with General Electric Engine Services, Inc. The
737-200 aircraft experienced an increase both in the number of engine
inspections and repairs and the average cost per repair.

Agency commissions per ASM decreased 9.1 percent primarily due to a decrease in
the percentage of commissionable revenues to 34.8 percent of total revenues in
1999 compared to 39.8 percent in 1998. The decrease in percentage of
commissionable revenues was primarily due to the growth in tickets purchased via
the Company's website from approximately 8 percent in 1998 to approximately 19
percent in 1999.

Aircraft rentals per ASM decreased 11.6 percent primarily due to a lower
percentage of the aircraft fleet being leased. Approximately 30.8 percent of the
Company's aircraft fleet were under operating lease at December 31, 1999,
compared to 35.4 percent at December 31, 1998.

Depreciation expense per ASM was flat for 1999 compared to 1998. Although the
Company owned a higher percentage of its aircraft fleet in 1999 versus 1998,
unit cost was flat due to a change in the estimated useful lives of the
Company's Boeing 737-300/-500 aircraft from 20 years to 23 years. See Note 2 to
the Consolidated Financial Statements. This change in accounting estimate was
made January 1, 1999, and resulted in a decrease to depreciation expense of
approximately $25.7 million for 1999.

Other operating expenses per ASM increased .7 percent primarily due to increased
credit card processing costs resulting from a higher percentage of the Company's
ticket sales purchased with credit cards.


16
18


OTHER "Other expenses (income)" included interest expense, capitalized interest,
interest income, and other gains and losses. Interest expense decreased 3.8
percent primarily due to the February 1998 redemption of $100 million of senior
unsecured 9 1/4% Notes originally issued in February 1991. Capitalized interest
increased 22.2 percent as a result of higher progress payment balances for
scheduled future aircraft deliveries. Interest income decreased 18.9 percent
primarily due to lower invested cash balances. Other losses in 1999 resulted
primarily from a write-down associated with the consolidation of certain
software development projects. Other gains in 1998 primarily consisted of
contractual penalties received from Boeing due to delays in the delivery of
737-700 aircraft.

INCOME TAXES The provision for income taxes, as a percentage of income before
taxes, increased slightly to 38.68 percent in 1999 from 38.53 percent in 1998.

LIQUIDITY AND CAPITAL RESOURCES

Net cash provided by operating activities was $1.3 billion in 2000 compared to
$1.0 billion in 1999. The increase in operating cash flows was primarily due to
the increase in operating income. Cash generated in 2000 was primarily used to
finance aircraft-related capital expenditures, provide working capital, and
repurchase approximately 6.7 million shares of Company stock.

During 2000, net capital expenditures were $1.1 billion, which primarily related
to the purchase of 33 new and one used 737-700 aircraft, and progress payments
for future aircraft deliveries.

At December 31, 2000, capital commitments of the Company primarily consisted of
scheduled aircraft acquisitions and related flight equipment. As of December 31,
2000, Southwest had 146 new 737-700s on firm order through 2007, including 25 to
be delivered in 2001. The Company also has options to purchase another 87
737-700s during 2003-2008 and purchase rights for an additional 217 737-700s
during 2007-2012. Aggregate funding required for firm commitments approximated
$4.0 billion through the year 2007, of which $668.3 million relates to 2001. See
Note 3 to the Consolidated Financial Statements for further information on
commitments.

On September 23, 1999, the Company announced its Board of Directors had
authorized the repurchase of up to $250 million of the Company's common stock.
Repurchases are made in accordance with applicable securities laws in the open
market or in private transactions from time to time, depending on market
conditions, and may be discontinued at any time. As of December 31, 2000, in
aggregate, 12.2 million shares had been repurchased at a total cost of $199.2
million, of which $108.7 million was completed in 2000.

The Company has various options available to meet its capital and operating
commitments, including cash on hand at December 31, 2000, of $523 million,
internally generated funds, and a revolving credit line with a group of banks of
up to $475 million (none of which had been drawn at December 31, 2000). In
addition, the Company will also consider various borrowing or leasing options to
maximize earnings and supplement cash requirements.

The Company currently has outstanding shelf registrations for the issuance of
$318.8 million of public debt securities, which it may utilize for aircraft
financings in 2001 and 2002.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Southwest has interest rate risk in that it holds floating rate debt instruments
and has commodity price risk in that it must purchase jet fuel to operate its
aircraft fleet. The Company purchases jet fuel at prevailing market prices, but
seeks to minimize its average jet fuel cost through execution of a documented
hedging strategy. Southwest has market sensitive instruments in the form of the
types of hedges it utilizes to decrease its exposure to jet fuel price increases
and with fixed rate debt instruments. The Company also operates 101 aircraft
under operating and capital leases. However, leases are not considered market
sensitive financial instruments and, therefore, are not included in the interest
rate sensitivity analysis below. Commitments related to leases are disclosed in
Note 6 to the Consolidated Financial Statements. The Company does not purchase
or hold any derivative financial instruments for trading purposes.

Airline operators are inherently dependent upon energy to operate and,
therefore, are impacted by changes in jet fuel prices. Jet fuel and oil consumed
in 2000 and 1999 represented approximately 17.4 and 12.5 percent of Southwest's
operating expenses, respectively. Southwest endeavors to acquire jet fuel at the
lowest prevailing prices possible. Because jet fuel is not traded on an
organized futures exchange, liquidity for hedging is limited. However, the
Company has found that crude oil contracts and heating oil contracts are
effective commodities for hedging jet fuel.

The Company utilizes financial derivative instruments for both short-term and
long-term time frames when it appears the Company can take advantage of market
conditions. At December 31, 2000, the Company had a mixture of purchased call
options, collar structures, and fixed price swap agreements in place to hedge
approximately 80 percent of its 2001 total anticipated jet fuel requirements,
approximately 32 percent of its 2002 total anticipated jet fuel requirements,
and a small portion of its 2005 total anticipated jet fuel requirements. As of
December 31, 2000, nearly all of the Company's 2001 hedges, and the majority of
its 2002 hedges, are effectively heating oil-based positions. All remaining
hedge positions are crude oil-based positions. The amounts related to all the
Company's fuel hedge positions contained in the Consolidated Balance Sheet at
December 31, 2000 was $22.5 million, which represents the aggregate net premium
cost paid for option and/or collar agreements. This amount is classified as
prepaid expense in current assets. The Company's fuel hedging strategy could
result in the Company not fully benefiting from certain jet fuel price declines.
See Note 7 to the Consolidated Financial Statements for further detail on the
Company's financial derivative instruments. Also see Recent Accounting
Developments in Note 1 to the Consolidated Financial Statements regarding the
new accounting requirements for financial derivative instruments effective
January 1, 2001.

The fair values of outstanding financial derivative instruments related to the
Company's jet fuel market price risk at December 31, 2000, including amounts
contained in the Consolidated Balance Sheet at December 31, 2000, was
approximately $98.3 million. A hypothetical ten


18
20


percent increase or decrease in the underlying fuel-related commodity prices
from the December 31, 2000, prices would correspondingly change the fair value
of the derivative commodity instruments in place and their related cash flows up
to approximately $2.4 million.

Airline operators are also inherently capital intensive, as the vast majority of
the Company's assets are aircraft, which are long-lived. The Company's strategy
is to capitalize conservatively and grow capacity steadily and profitably. While
the Company uses financial leverage, it has maintained a strong balance sheet
and an "A" credit rating on its senior unsecured fixed-rate debt with Standard &
Poor's and a "A-" or equivalent credit ratings with two other rating agencies
(Moody's and Fitch). The Company's Aircraft Secured Notes ($200 million) and
French Credit Agreements ($54 million) do not give rise to significant fair
value risk but do give rise to interest rate risk because these borrowings are
floating-rate debt. Although there is interest rate risk associated with these
secured borrowings, the risk is somewhat mitigated by the fact that the Company
may prepay this debt on any of the semi-annual principal and interest payment
dates. See Note 5 to the Consolidated Financial Statements for more information
on these borrowings.

As disclosed in Note 5 to the Consolidated Financial Statements, the Company had
outstanding senior unsecured notes totaling $500 million at December 31, 2000
and 1999. These long-term notes represent only 8.6 percent and 10.0 percent of
total noncurrent assets at December 31, 2000 and 1999, respectively. The
unsecured long-term debt currently has an average maturity of 8.1 years at fixed
rates averaging 8.3 percent at December 31, 2000, which is comparable to average
rates prevailing over the last ten years. The Company does not have significant
exposure to changing interest rates on its unsecured long-term debt because the
interest rates are fixed and the financial leverage is modest.

Additionally, the Company does not have significant exposure to changing
interest rates on invested cash, which was $523 million and $419 million at
December 31, 2000 and 1999, respectively. The Company invests available cash in
certificates of deposit and investment grade commercial paper that generally
have maturities of three months or less. As a result, the interest rate market
risk implicit in these investments at December 31, 2000, is low, as the
investments generally mature within three months. The Company has not undertaken
any additional actions to cover interest rate market risk and is not a party to
any other material interest rate market risk management activities.

A hypothetical ten percent change in market interest rates over the next year
would not have a material effect on the fair value of the Company's debt
instruments or its short-term cash investments. See Note 7 to the Consolidated
Financial Statements for further information on the fair value of the Company's
financial instruments. Because of the floating rate nature of the Company's
secured borrowings, a ten percent change in market interest rates as of December
31, 2000, would correspondingly change the Company's earnings and cash flows by
approximately $1.1 million in 2001. However, a ten percent change in market
rates would not impact the Company's earnings or cash flow associated with the
Company's publicly traded fixed-rate debt or its cash investments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
December 31, 2000

1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION Southwest Airlines Co. (Southwest) is a major domestic
airline that provides primarily shorthaul, high-frequency, point-to-point,
low-fare service. The consolidated financial statements include the accounts of
Southwest and its wholly owned subsidiaries (the Company). All significant
intercompany balances and transactions have been eliminated. The preparation of
financial statements in conformity with accounting principles generally accepted
in the United States requires management to make estimates and assumptions that
affect the amounts reported in the financial statements and accompanying notes.
Actual results could differ from these estimates. Certain prior year amounts
have been restated to conform to the current year presentation.

CASH AND CASH EQUIVALENTS Cash equivalents consist of certificates of deposit
and investment grade commercial paper issued by major corporations and financial
institutions. Cash and cash equivalents are highly liquid and generally have
original maturities of three months or less. Cash and cash equivalents are
carried at cost, which approximates market value.

INVENTORIES Inventories of flight equipment expendable parts, materials, and
supplies are carried at average cost. These items are generally charged to
expense when issued for use.

PROPERTY AND EQUIPMENT Depreciation is provided by the straight-line method to
estimated residual values over periods ranging from 20 to 25 years for flight
equipment and 3 to 30 years for ground property and equipment. See Note 2 for
further information on aircraft depreciation. Property under capital leases and
related obligations are recorded at an amount equal to the present value of
future minimum lease payments computed on the basis of the Company's incremental
borrowing rate or, when known, the interest rate implicit in the lease.
Amortization of property under capital leases is on a straight-line basis over
the lease term and is included in depreciation expense. The Company records
impairment losses on long-lived assets used in operations when events and
circumstances indicate that the assets might be impaired and the undiscounted
cash flows to be generated by those assets are less than the carrying amounts of
those assets.

AIRCRAFT AND ENGINE MAINTENANCE The cost of scheduled engine inspections and
repairs and routine maintenance costs for aircraft and engines are charged to
maintenance expense as incurred. Scheduled airframe inspections and repairs,
known as "D" checks, are generally performed every ten years. Costs related to
"D" checks are capitalized and amortized over the estimated period benefited,
presently the least of ten years, the time until the next "D" check, or the
remaining life of the aircraft. Modifications that significantly enhance the
operating performance or extend the useful lives of aircraft or engines are
capitalized and amortized over the remaining life of the asset.

26


REVENUE RECOGNITION Passenger revenue is recognized when transportation is
provided. Tickets sold but not yet used are included in "Air traffic liability,"
which includes estimates that are evaluated and adjusted periodically. Any
adjustments resulting therefrom are included in results of operations for the
periods in which the evaluations are completed.

FREQUENT FLYER PROGRAM The Company accrues the estimated incremental cost of
providing free travel for awards earned under its Rapid Rewards frequent flyer
program. The Company also sells flight segment credits and related services to
companies participating in its Rapid Rewards frequent flyer program. Prior to
2000, revenue from the sale of flight segment credits was recognized when the
credits were sold. However, beginning January 1, 2000, funds received from the
sale of flight segment credits and associated with future travel is deferred and
recognized as "Passenger revenue" when the ultimate free travel awards are flown
or the credits expire unused (see Note 2).

ADVERTISING The Company expenses the costs of advertising as incurred.
Advertising expense for the years ended December 31, 2000, 1999, and 1998 was
$141.3 million, $137.7 million, and $119.7 million, respectively.

STOCK-BASED EMPLOYEE COMPENSATION Pursuant to Statement of Financial Accounting
Standards No. 123 (SFAS 123), Accounting for Stock-Based Compensation, the
Company accounts for stock-based compensation plans utilizing the provisions of
Accounting Principles Board Opinion No. 25 (APB 25), Accounting for Stock Issued
to Employees and related Interpretations. See Note 9.

FINANCIAL DERIVATIVE INSTRUMENTS The Company utilizes a variety of derivative
instruments, including both crude oil and heating oil based derivatives, to
hedge a portion of its exposure to jet fuel price increases. These instruments
consist primarily of purchased call options, collar structures, and fixed price
swap agreements. The net cost paid for option premiums and gains and losses on
fixed price swap agreements, including those terminated or settled early, are
deferred and charged or credited to fuel expense in the same month that the
underlying jet fuel being hedged is used. Hedging gains and losses are recorded
as a reduction of fuel and oil expense. Beginning January 1, 2001, the Company
will adopt Statement of Financial Accounting Standards No. 133 (SFAS 133),
Accounting for Derivative Instruments and Hedging Activities which will change
the way it accounts for financial derivative instruments. See Recent Accounting
Developments.

RECENT ACCOUNTING DEVELOPMENTS In 1998, the Financial Accounting Standards Board
(FASB) issued SFAS 133. SFAS 133, as amended, is required to be adopted in
fiscal years beginning after June 15, 2000. The Company will adopt SFAS 133
effective January 1, 2001. SFAS 133 will require the Company to record all
derivatives on its balance sheet at fair value. Derivatives that are not
designated as hedges must be adjusted to fair value through income. If the
derivative is designated as a hedge, depending on the nature of the hedge,
changes in the fair value of derivatives that are considered to be effective, as
defined, will either offset the change in fair value of the hedged assets,
liabilities, or firm commitments through earnings or will be recorded in other
comprehensive income until the hedged item is recorded in earnings. Any portion
of a change in a derivative's fair value that is considered to be ineffective,
as defined, may have to be immediately recorded in


25
27


earnings. Any portion of a change in a derivative's fair value that the Company
has elected to exclude from its measurement of effectiveness, such as the change
in time value of option contracts, will be recorded in earnings.

The Company will account for its fuel hedge derivative instruments as cash flow
hedges, as defined. Although the fair value of the Company's derivative
instruments fluctuates daily, as of January 1, 2001, the fair value of the
Company's fuel hedge derivative instruments was approximately $98.3 million, of
which approximately $75.8 million was not recorded in the Consolidated Balance
Sheet. The $75.8 million will be recorded as an asset on the Company's balance
sheet as part of the transition adjustment related to the Company's adoption of
SFAS 133. The offset to this balance sheet adjustment will be an increase to
"Accumulated other comprehensive income", a component of stockholders' equity.
The portion of the transition adjustment in "Accumulated other comprehensive
income" that relates to 2001 hedge positions, based on fair value as of January
1, 2001, is approximately $73.9 million and will be reclassified into earnings
during 2001. The remainder of the transition amount will be reclassified to
earnings in periods subsequent to 2001. The Company believes the adoption of
SFAS 133 will result in more volatility in its financial statements than in the
past.

2. ACCOUNTING CHANGES

Effective January 1, 2000, the Company adopted Staff Accounting Bulletin 101
(SAB 101) issued by the Securities and Exchange Commission in December 1999. As
a result of adopting SAB 101, the Company changed the way it recognizes revenue
from the sale of flight segment credits to companies participating in its Rapid
Rewards frequent flyer program. Prior to the issuance of SAB 101, the Company
recorded revenue to "Other revenue" when flight segment credits were sold,
consistent with most other major airlines. Beginning January 1, 2000, the
Company recognizes "Passenger revenue" when free travel awards resulting from
the flight segment credits sold are earned and flown or credits expire unused.
Due to this change, the Company recorded a cumulative adjustment in first
quarter 2000 of $22.1 million (net of income taxes of $14.0 million) or $.04 per
share, basic and diluted. The impact in 2000 of adopting SAB 101 was to reduce
net income, before the cumulative effect of accounting change, by $4.6 million.
Excluding the impact of the change, basic and diluted net income per share for
2000, before the cumulative effect of accounting change, would have been $1.26
and $1.19, respectively. The Company also reclassified for comparison purposes
the revenue reported in prior periods related to the sale of flight segment
credits from "Other revenue" to "Passenger revenue."

Adopting this new method of accounting for 1999 and 1998 would have produced the
following pro forma results (in thousands, except per share amounts):


26

As reported, before the cumulative
effect of accounting change 2000 1999 1998
----------- ----------- -----------


Net income $ 625,224 $ 474,378 $ 433,431
Net income per share, basic $ 1.25 $ .94 $ .87
Net income per share, diluted $ 1.18 $ .89 $ .82

Net income per share, basic $ 1.25 $ .94 $ .86
Net income per share, diluted $ 1.18 $ .88 $ .81


Effective January 1, 1999, the Company revised the estimated useful lives of its
737-300 and -500 aircraft from 20 years to 23 years. This change was the result
of the Company's assessment of the remaining useful lives of the aircraft based
on the manufacturer's design lives, the Company's increased average aircraft
stage (trip) length, and the Company's previous experience. The effect of this
change was to reduce depreciation expense approximately $25.7 million and
increase net income $.03 per diluted share for the year ended December 31, 1999.

3. COMMITMENTS

The Company's contractual purchase commitments consist primarily of scheduled
aircraft acquisitions. Twenty-five 737-700 aircraft are scheduled for delivery
in 2001, 27 in 2002, 13 in 2003, 29 in 2004, five in 2005, and 47 thereafter. In
addition, the Company has options to purchase up to 87 737-700s during 2003-2008
and purchase rights for an additional 217 737-700s during 2007-2012. The Company
has the option, which must be exercised two years prior to the contractual
delivery date, to substitute 737-600s or 737-800s for the 737-700s scheduled
subsequent to 2001. Aggregate funding needed for firm commitments is
approximately $4.0 billion, subject to adjustments for inflation, due as
follows: $668.3 million in 2001, $766.3 million in 2002, $472.2 million in 2003,
$640.7 million in 2004, $379.4 million in 2005, and $1.0 billion thereafter.

In fourth quarter 1999, the Company issued $200 million of floating rate
Aircraft Secured Notes, due 2004. The Notes are funded by a bank through a
commercial paper conduit program and are secured by eight aircraft. Interest
rates on the Notes are based on the conduit's actual commercial paper rate, plus
fees, for each period and are expected to average approximately LIBOR plus 36
basis points over the term of the Notes. Interest is payable monthly and the
Company can prepay the Notes in whole or in part prior to maturity.

Also in fourth quarter 1999, the Company entered into two identical 13-year
floating rate financing arrangements, whereby it effectively borrowed a total of
$56 million from French banking partnerships. For presentation purposes, the
Company has classified these identical borrowings as one $56 million
transaction. The effective rate of interest over the 13-year term of the loans
is LIBOR plus 32 basis points. Principal and interest are payable semi-annually
on June 30 and December 31 for each of the loans and the Company may terminate
the arrangements in any year on either of those dates, with certain conditions.
The Company has pledged two aircraft as collateral for the entire transaction.

On February 28, 1997, the Company issued $100 million of senior unsecured 7 3/8%
Debentures due March 1, 2027. Interest is payable semi-annually on March 1 and
September 1. The Debentures may be redeemed, at the option of the Company, in
whole at any time or in part from time to time, at a redemption price equal to
the greater of the principal amount of the Debentures plus accrued interest at
the date of redemption or the sum of the present values of the remaining
scheduled payments of principal and interest thereon, discounted to the date of
redemption at the comparable treasury rate plus 20 basis points, plus accrued
interest at the date of redemption.

On March 7, 1995, the Company issued $100 million of senior unsecured 8% Notes
due March 1, 2005. Interest is payable semi-annually on March 1 and September 1.
The Notes are not redeemable prior to maturity.

$100 million of senior unsecured 8 3/4% Notes due July 1, 2001 and October 15,
2003, respectively. Interest on the Notes is payable semi-annually. The Notes
are not redeemable prior to maturity.

In addition to the credit facilities described above, Southwest has an unsecured
Bank Credit Agreement with a group of banks that permits Southwest to borrow
through May 6, 2002, on a revolving credit basis, up to $475 million. Interest
rates on borrowings under the Credit Agreement can be, at the option of
Southwest, the greater of the agent bank's prime rate or the federal funds rate
plus 50 basis points, LIBOR plus 17 basis points, or a fixed rate offered by the
banks at the time of borrowing. The commitment fee is 8 basis points per annum.
There were no outstanding borrowings under this agreement, or prior similar
agreements, at December 31, 2000 and 1999.

6. LEASES

Total rental expense for operating leases charged to operations in 2000, 1999,
and 1998 was $330.7 million, $318.2 million, and $305.2 million, respectively.
The majority of the Company's terminal operations space, as well as 94 aircraft,
were under operating leases at December 31, 2000. The amounts applicable to
capital leases included in property and equipment were:

The aircraft leases generally can be renewed at rates based on fair market value
at the end of the lease term for one to five years. Most aircraft leases have
purchase options at or near the end of the lease term at fair market value, but
generally not to exceed a stated percentage of the lessor's defined cost of the
aircraft.

7. FINANCIAL INSTRUMENTS

The Company utilizes a variety of financial derivative instruments to hedge a
portion of its exposure to jet fuel price increases. During 2000 and 1999, the
Company recognized gains of $113.5 million and $14.8 million, respectively, from
hedging activities. At December 31, 2000, approximately $49.9 million was due
from third parties, and accordingly, is included in "Accounts and other
receivables" in the accompanying Consolidated Balance Sheet. For further details
of the Company's fuel hedge positions at December 31, 2000, see Quantitative
and Qualitative Disclosures about Market Risk and Recent Accounting Developments
in Note 1. The fair value of the Company's financial derivative instruments at
December 31, 2000, was approximately $98.3 million.

Any outstanding financial derivative instruments expose the Company to credit
loss in the event of nonperformance by the counterparties to the agreements, but
the Company does not expect any of the counterparties to fail to meet their
obligations. The credit exposure related to these financial instruments is
represented by the fair value of contracts with a positive fair value at the
reporting date. To manage credit risks, the Company selects counterparties based
on credit ratings, limits its exposure to a single counterparty, and monitors
the market position of the program and its relative market position with each
counterparty. At December 31, 2000, the Company had an agreement with two
counterparties containing bilateral collateral provisions whereby cash deposits
are required if market risk exposure exceeds a specified threshold amount.
Neither the Company nor the


30
32


counterparties exceeded the threshold amount at December 31, 2000. The Company
is in the process of negotiating similar agreements with other counterparties.

The Company does not hold or issue any financial instruments for trading
purposes.

The carrying amounts and estimated fair values of the Company's long-term debt
at December 31, 2000 were as follows:



(In thousands) CARRYING VALUE FAIR VALUE
-------------- ----------

8 3/4% Notes due 2003 $100,000 $104,854
Aircraft Secured Notes due 2004 200,000 200,000
8% Notes due 2005 100,000 104,143
7 7/8% Notes due 2007 100,000 102,620
French Credit Agreements 54,243 54,243
7 3/8% Debentures due 2027 100,000 92,092


The estimated fair values of the Company's long-term debt were based on quoted
market prices. The carrying values of all other financial instruments
approximate their fair value.

8. COMMON STOCK

The Company has one class of common stock. Holders of shares of common stock are
entitled to receive dividends when and if declared by the Board of Directors and
are entitled to one vote per share on all matters submitted to a vote of the
shareholders.

At December 31, 2000, the Company had common stock reserved for issuance
pursuant to Employee stock benefit plans (101.2 million shares) and upon
exercise of rights (179.4 million shares) pursuant to the Common Share Purchase
Rights Agreement, as amended (Agreement).

Pursuant to the Agreement, each outstanding share of the Company's common stock
is accompanied by one common share purchase right (Right). Each Right is
exercisable only in the event of a proposed takeover, as defined by the
Agreement. The Company may redeem the Rights at $.0033 per Right prior to the
time that 15 percent of the common stock has been acquired by a person or group.
If the Company is acquired, as defined in the Agreement, each Right will entitle
its holder to purchase for $4.94 that number of the acquiring company's or the
Company's common shares, as provided in the Agreement, having a market value of
two times the exercise price of the Right. The Rights will expire no later than
July 30, 2006.

On July 22, 1998, the Company's Board of Directors declared a three-for-two
stock split, distributing 111.9 million shares on August 20, 1998. On May 20,
1999, the Company's Board of Directors declared a three-for-two stock split,
distributing 168.0 million shares on July 19, 1999. Unless


31
33


otherwise stated, all share and per share data presented in the accompanying
consolidated financial statements and notes thereto have been restated to give
effect to these stock splits.

During third quarter 1998, the Company completed a $100 million common stock
repurchase program, resulting in the repurchase of 7.3 million shares at an
average cost of $13.65 per share. All of the acquired shares were subsequently
reissued under Employee stock plans.

On September 23, 1999, the Company's Board of Directors authorized the Company
to repurchase up to $250 million of its outstanding common stock. As of December
31, 2000, this program had resulted in the repurchase of 12.2 million shares at
an average cost of $16.28 per share. All of the acquired shares are held as
common stock in treasury, less shares reissued under Employee stock option and
purchase plans. When treasury shares are reissued, the Company uses a first-in,
first-out method and the excess of repurchase cost over reissuance price, if
any, is treated as a reduction of retained earnings.

On January 18, 2001, the Company's Board of Directors declared a three-for-two
stock split, payable to shareholders of record at the close of business on
January 26, 2001, and also increased the quarterly dividend. Shares will be
distributed on February 15, 2001. The dividend will be adjusted to $.0045 per
share quarterly on the increased number of shares outstanding. The share and per
share data presented in the accompanying consolidated financial statements and
notes thereto has not been restated to give effect to this pending 2001 stock
split.

9. STOCK PLANS

At December 31, 2000, the Company had twelve stock-based compensation plans and
other stock options outstanding, which are described below. The Company applies
APB 25 and related Interpretations in accounting for its stock-based
compensation. Accordingly, no compensation expense is recognized for its fixed
option plans because the exercise prices of the Company's Employee stock options
equal or exceed the market prices of the underlying stock on the dates of grant.
Compensation expense for other stock options is not material.

The Company has eleven fixed option plans that cover various Employee groups.
Under these plans, the Company may grant up to 127 million shares of common
stock, of which 24.6 million shares were available for granting in future
periods as of December 31, 2000. Under plans covered by collective bargaining
agreements, options granted to Employees generally have terms similar to the
term of, and vest in annual increments over the remaining life of, the
respective collective bargaining agreement. Options granted to Employees not
covered by collective bargaining agreements have ten-year terms and vest and
become fully exercisable over three, five, or ten years of continued employment,
depending upon the grant type.

Aggregated information regarding the Company's eleven fixed stock option plans,
as adjusted for stock splits, is summarized below:

The Company has granted options to purchase the Company's common stock related
to employment contracts with the Company's president and chief executive
officer. Depending upon the grant, these options have terms of ten years from
the date of grant or ten years from the date exercisable and vest and become
fully exercisable over three or four years. No options were granted in 2000,
1999, or 1998. At December 31, 2000, 1999, and 1998, total options of 4.1
million, 5.0 million, and 5.5 million were outstanding, respectively. At
December 31, 2000, total options of 4.1 million were exercisable at exercise
prices ranging from $1.00 to $6.96 per share. Options for 854,000, 570,000, and
342,000 shares were exercised in 2000, 1999, and 1998, respectively.

Under the 1991 Employee Stock Purchase Plan (ESPP), as amended, at December 31,
2000, the Company is authorized to issue up to a remaining balance of 5.9
million shares of common stock


33
35


to Employees of the Company at a price equal to 90 percent of the market value
at the end of each purchase period. Common stock purchases are paid for through
periodic payroll deductions. Participants under the plan received 686,000 shares
in 2000, 649,000 shares in 1999, and 677,000 shares in 1998 at average prices of
$20.01, $16.24, and $11.63, respectively.

Pro forma information regarding net income and net income per share is required
by SFAS 123 and has been determined as if the Company had accounted for its
Employee stock-based compensation plans and other stock options under the fair
value method of SFAS 123. The fair value of each option grant is estimated on
the date of grant using the Black-Scholes option pricing model with the
following weighted-average assumptions used for grants under the fixed option
plans in 2000, 1999, and 1998, respectively: dividend yield of .10 percent, .12
percent, and .16 percent; expected volatility of 34.87 percent, 35.66 percent,
and 38.20 percent; risk-free interest rate of 5.04 percent, 6.68 percent, and
4.66 percent; expected lives of 6.0 years for 2000, and 5.0 years for 1999 and
1998.

The fair value of options granted under the fixed option plans during 2000
ranged from $6.70 to $14.69. The fair value of options granted under the fixed
option plans during 1999 ranged from $6.26 to $8.81. The fair value of options
granted under the fixed option plans during 1998 ranged from $4.41 to $4.97. The
weighted-average fair value of each purchase right under the ESPP granted in
2000, 1999, and 1998, which is equal to the ten percent discount from the market
value of the common stock at the end of each purchase period, was $2.22, $1.75,
and $1.29, respectively.

The Black-Scholes option valuation model was developed for use in estimating the
fair value of traded options which have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions including expected stock price volatility. Because the
Company's Employee stock options have characteristics significantly different
from those of traded options and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its Employee stock options.

For purposes of pro forma disclosures, the estimated fair value of stock-based
compensation plans and other options is amortized to expense primarily over the
vesting period. The Company's pro forma net income and net income per share are
as follows:


34
36




(In thousands except per share amounts) 2000 1999 1998
----------- ----------- -----------

NET INCOME:
As reported $ 603,093 $ 474,378 $ 433,431

Pro forma $ 1.17 $ .92 $ .84
NET INCOME PER SHARE, DILUTED:
As reported $ 1.14 $ .89 $ .82
Pro forma $ 1.11 $ .87 $ .79


As required, the pro forma disclosures above include only options granted since
January 1, 1995. Consequently, the effects of applying SFAS 123 for providing
pro forma disclosures may not be representative of the effects on reported net
income for future years until all options outstanding are included in the pro
forma disclosures.

10. EMPLOYEE RETIREMENT PLANS

The Company has defined contribution plans covering substantially all of
Southwest's Employees. The Southwest Airlines Co. Profitsharing Plan is a money
purchase defined contribution plan and Employee stock purchase plan. The Company
also sponsors Employee savings plans under section 401(k) of the Internal
Revenue Code, which include Company matching contributions. The 401(k) plans
cover substantially all Employees. Contributions under all defined contribution
plans are based primarily on Employee compensation and performance of the
Company.

Company contributions to all retirement plans expensed in 2000, 1999, and 1998
were $241.5 million, $192.0 million, and $167.1 million, respectively.

11. INCOME TAXES

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. The components of
deferred tax assets and liabilities at December 31, 2000 and 1999, are as
follows:

The Company received a statutory notice of deficiency from the Internal Revenue
Service (IRS) in July 1995 in which the IRS proposed to disallow deductions
claimed by the Company on its federal income tax returns for the taxable years
1989 through 1991 for the costs of certain aircraft inspection and maintenance
procedures. The IRS has proposed similar adjustments to the tax returns of
numerous other members of the airline industry. In response to the statutory
notice of deficiency, the Company filed a petition in the United States Tax
Court on October 30, 1997, seeking a determination that the IRS erred in
disallowing the deductions claimed by the Company and there is no deficiency in
the Company's tax liability for the taxable years in issue. On December 21,
2000, the national office of the IRS published a revenue ruling in which it
concluded that aircraft inspection and maintenance, substantially the same as
that in issue in the Company's Tax Court suit, is currently deductible as an
ordinary and necessary business expense. Counsel for the Company and the IRS
soon will engage in discussions in an attempt to resolve the controversy in
conformity with the IRS revenue ruling and without the necessity of further
litigation. Management believes the final


36
38


resolution of this controversy will not have a material adverse effect upon the
financial position or results of operations of the Company.

INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND SHAREHOLDERS
SOUTHWEST AIRLINES CO.

We have audited the accompanying consolidated balance sheets of Southwest

statements of income, stockholders' equity, and cash flows for each of the three
years in the period ended December 31, 2000. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of Southwest Airlines
Co. at December 31, 2000 and 1999, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 2000, in conformity with accounting principles generally accepted
in the United States.
