SOUTHWEST REPORTS THIRD QUARTER PROFIT

DALLAS, TEXAS - October 25, 2018 - Southwest Airlines Co. (NYSE:LUV) (the “Company”) today reported its third quarter 2018 results:

Record third quarter net income of $615 million
Net income of $614 million, excluding special items1 
Record third quarter earnings per diluted share of $1.08
Operating income of $798 million, or $796 million, excluding special items
Operating margin2 of 14.3 percent, and net margin3 of 11.0 percent
Operating cash flow of $1.3 billion, and free cash flow1 of $817 million
Returned $591 million to Shareholders through a combination of share repurchases and dividends
Return on invested capital (ROIC)1 pre-tax of 23.4 percent for the 12 months ended September 30, 2018, or 18.1 percent on an after-tax basis

Gary C. Kelly, Chairman of the Board and Chief Executive Officer, stated, “I want to congratulate our Employees on an excellent third quarter 2018 performance, resulting in record third quarter earnings per diluted share. The significant increase in our third quarter 2018 earnings per diluted share was driven by record third quarter operating revenues, lower federal income taxes, and a 4.8 percent year-over-year reduction in share count. Despite higher jet fuel prices and other cost pressures, we grew our third quarter 2018 net margin, year-over-year, which is a notable accomplishment.

"I am grateful to our People for their hard work and resilience, as we continue to consistently deliver stellar margins and returns. With these results, we accrued an additional $135 million in profitsharing for the benefit of our Employees and provided $591 million of share buybacks and dividends for our Shareholders.

"As we finish the year, our revenue momentum has continued into fourth quarter 2018, thus far. Unit revenue trends are stable and have recovered nicely from first half 2018. We are particularly pleased with the performance of our new revenue management tools. With our new reservation system in place since last year, we have more capabilities and are well-positioned to drive revenue growth. We expect $80 million to $90 million of year-over-year improvement in fourth quarter 2018 pre-tax results from these enhanced capabilities, which is in line with our annual 2018 pre-tax goal of $200 million.






"On the cost side, our third quarter 2018 unit cost performance was in line with our expectations. Our fuel hedge portfolio mitigated a significant portion of market jet fuel price increases, and we are pleased with the fuel hedge in place for both fourth quarter 2018 and annual 2019. Based on current trends, we continue to expect modest year-over-year inflation in our annual 2018 unit costs, excluding fuel and oil expense and profitsharing expense.

"Based on our second half 2018 revenue trends, we are well-positioned for year-over-year unit revenue growth in 2019, with easier year-over-year comparisons in first half. We also will continue to experience year-over-year unit cost inflation in 2019, excluding fuel and oil expense and profitsharing expense, of at least three percent, as we continue investing in and deploying new operations, technology, and airport infrastructure to support future growth. With the 2017 retirement of our Boeing 737-300 Classic fleet, launch of the 737 MAX, and implementation of our new reservation system, we continue with our efforts to modernize our fleet, optimize our network, and pursue additional revenue opportunities. Given our healthy revenue outlook, and despite expected cost increases, our 2019 goal is to expand margins year-over-year. We are refocusing our efforts to control costs and drive efficiency, and, as ever, we remain steadfast in our efforts to produce industry-leading margins and superior returns in excess of our cost of capital.

"For next year, Hawaii is our expansion focus, and we continue to expect 2019 available seat miles (ASMs, or capacity) to increase no more than five percent, year-over-year."

Revenue Results and Outlook
The Company's third quarter 2018 total operating revenues increased 5.1 percent, year-over-year, to a third quarter record $5.6 billion. Third quarter 2018 operating revenue per ASM (RASM, or unit revenues) increased 1.2 percent, year-over-year, driven largely by a passenger revenue yield increase of 2.3 percent, year-over-year, offset slightly by a load factor decline of 0.9 points, year-over-year, to 83.9 percent. Third quarter 2018 RASM also included an approximate one-half point year-over-year positive impact as a result of approximately 2,200 flight cancellations in third quarter 2018, due to thunderstorms and weather-related disruptions (the "weather cancellations").

Based on current bookings and yield trends, the Company expects fourth quarter 2018 RASM to increase in the one to two percent range, compared with fourth quarter 2017 RASM of 13.88 cents, as recast in accordance with Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (or the "New Revenue Standard"). The Company adopted the New Revenue Standard effective January 1, 2018, and utilized the full retrospective method of adoption allowed by the standard. As such, results for the three and nine months ended September 30, 2017, have been recast





under the new standard in order to be comparable with current period results in the accompanying unaudited Condensed Consolidated Statement of Income. The Company's third quarter 2018 year-over-year RASM increase included an approximate one point headwind from the change in the Rapid Rewards revenue recognition method as a result of the Company's adoption of the New Revenue Standard. The Company continues to expect an immaterial impact to its fourth quarter and annual 2018 year-over-year RASM trends as a result of the New Revenue Standard.

Cost Performance and Outlook
Third quarter 2018 total operating expenses increased 7.2 percent, year-over-year, to $4.8 billion. Total operating expenses per ASM (CASM, or unit costs) increased 3.1 percent, as compared with third quarter 2017. Excluding special items in both periods, third quarter 2018 total operating expenses increased 8.1 percent to $4.8 billion, or 4.1 percent on a unit basis, year-over-year.

Effective January 1, 2018, the Company early adopted ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities. The new standard eliminated ineffectiveness for all derivatives designated in a hedge for accounting purposes, as well as changed the Company's classification of premium expense associated with fuel hedges from Other (gains) and losses, net, to Fuel and oil expense within the unaudited Condensed Consolidated Statement of Income. As such, the classification of premium expense for the three and nine months ended September 30, 2017, has been recast under the new standard to be comparable with current period results.

Third quarter 2018 economic fuel costs1 were $2.25 per gallon and included $.06 per gallon in premium expense and $.10 per gallon in favorable cash settlements from fuel derivative contracts, compared with $2.07 per gallon in third quarter 2017, as recast, which included $.06 per gallon in premium expense and $.31 per gallon in unfavorable cash settlements from fuel derivative contracts. Third quarter 2018 ASMs per gallon, or fuel efficiency, improved 1.1 percent year-over-year, driven primarily by the retirement of the Classic fleet and the addition of more fuel-efficient 737-800 and 737 MAX 8 aircraft.

Based on the Company's existing fuel derivative contracts and market prices as of October 19, 2018, fourth quarter 2018 economic fuel costs are estimated to be in the range of $2.30 to $2.35 per gallon4, including $.07 per gallon in premium expense and an estimated $.14 per gallon in favorable cash settlements from fuel derivative contracts, compared with $2.16 per gallon in fourth quarter 2017, as recast, which included $.07 per gallon in premium expense and $.19 per gallon in unfavorable cash settlements from fuel derivative contracts. As of October 19, 2018, the fair market value of the Company's fuel derivative contracts settling in fourth quarter 2018 was an asset of approximately $82





million, and the fair market value of the hedge portfolio settling in 2019 and beyond was an asset of approximately $521 million.

Based on the Company's existing fuel derivative contracts and market prices as of October 19, 2018, annual 2019 economic fuel costs are estimated to be in the range of $2.35 to $2.40 per gallon4, including $.04 per gallon in premium expense and an estimated $.08 per gallon in favorable cash settlements from fuel derivative contracts. Additional information regarding the Company's fuel derivative contracts is included in the accompanying tables.

Excluding fuel and oil expense and special items in both periods, third quarter 2018 operating expenses increased 7.0 percent, as compared with third quarter 2017. Third quarter 2018 profitsharing expense was $135 million, as compared with $127 million in third quarter 2017. Excluding fuel and oil expense, profitsharing expense, and special items, third quarter 2018 operating expenses also increased 7.0 percent, or 3.0 percent on a unit basis, year-over-year. This increase was due primarily to shifting of spending from first half 2018 into third quarter 2018, higher maintenance and advertising expenses, and a nearly one-point year-over-year negative impact as a result of the third quarter 2018 weather cancellations.

Based on current cost trends, the Company estimates fourth quarter 2018 CASM, excluding fuel and oil expense and profitsharing expense, to be flat to up one percent, compared with fourth quarter 2017's 8.82 cents, as recast, which excluded fuel and oil expense, profitsharing expense, and special items. The Company continues to estimate annual 2018 CASM, excluding fuel and oil expense and profitsharing expense, to be flat to up one percent, compared with annual 2017's 8.47 cents, as recast, which excluded fuel and oil expense, profitsharing expense, and special items.

Third Quarter Results
Third quarter 2018 net income was a third quarter record $615 million, or a record third quarter $1.08 per diluted share, compared with third quarter 2017 net income of $528 million, or $.88 per diluted share. Excluding special items, third quarter 2018 net income was $614 million, or a third quarter record $1.08 per diluted share, compared with third quarter 2017 net income of $554 million, or $.93 per diluted share, and compared with First Call third quarter 2018 consensus estimate of $1.06 per diluted share.

The Company estimates its effective tax rate to be approximately 23 percent for annual 2018. For annual 2019, the Company estimates its effective tax rate to be approximately 23.5 percent.






Liquidity and Capital Deployment
As of September 30, 2018, the Company had approximately $3.8 billion in cash and short-term investments, and a fully available unsecured revolving credit line of $1 billion. Net cash provided by operations during third quarter 2018 was $1.3 billion, capital expenditures were $454 million, and free cash flow was $817 million. The Company repaid $98 million in debt and capital lease obligations during third quarter 2018, and expects to repay approximately $87 million in debt and capital lease obligations during fourth quarter 2018.

During third quarter 2018, the Company returned $591 million to its Shareholders through the repurchase of $500 million in common stock and the payment of $91 million in dividends. The Company repurchased 8.2 million shares of common stock pursuant to a $500 million accelerated share repurchase program (ASR) launched during third quarter 2018 and completed earlier this month. The Company's third quarter ASR completed the remaining $350 million of its previous $2.0 billion share repurchase program that had been authorized by its Board of Directors in May 2017, and initiated the $2.0 billion share repurchase program authorized by its Board of Directors in May 2018. The Company has $1.85 billion remaining under its current authorization.

For the nine months ended September 30, 2018, net cash provided by operations was approximately $3.9 billion. Capital expenditures, including net proceeds from assets constructed for others, were approximately $1.3 billion, and free cash flow was $2.6 billion. This enabled the Company to return approximately $1.8 billion to Shareholders through the repurchase of $1.5 billion in common stock and the payment of $332 million in dividends.

The Company continues to estimate its annual 2018 capital expenditures to be in the $2.0 to $2.1 billion range. For annual 2019, capital expenditures are expected to be similar to 2018 levels.

Fleet and Capacity
The Company ended third quarter 2018 with 742 aircraft in its fleet. This reflects the third quarter delivery of five new 737-800s and seven new 737 MAX 8s. The Company continues to expect to end 2018 with 751 aircraft in its fleet based on the current aircraft delivery schedule. Additional information regarding the Company's aircraft delivery schedule is included in the accompanying tables.

The Company now expects its annual 2018 year-over-year ASM growth to be approximately four percent, slightly lower than previously expected, due primarily to the third quarter 2018 weather cancellations. The Company now expects fourth quarter 2018 year-over-year ASM growth to be in the 6.0 to 6.5 percent range.

(a) A revenue passenger mile is one paying passenger flown one mile. Also referred to as "traffic," which is a measure of demand for a given period.
(b) An available seat mile is one seat (empty or full) flown one mile. Also referred to as "capacity," which is a measure of the space available to carry passengers in a given period.
(c) Revenue passenger miles divided by available seat miles.
(d) Seats flown is calculated using total number of seats available by aircraft type multiplied by the total trips flown by the same aircraft type during a particular period.
(e) Seats per trip is calculated using seats flown divided by trips flown. Also referred to as “gauge.”
(f) Calculated as passenger revenue divided by revenue passenger miles. Also referred to as "yield," this is the average cost paid by a paying passenger to fly one mile, which is a measure of revenue production and fares.
(g) RASM (unit revenue) - Operating revenue yield per ASM, calculated as operating revenue divided by available seat miles. Also referred to as "operating unit revenues," this is a measure of operating revenue production based on the total available seat miles flown during a particular period.
(h) PRASM (Passenger unit revenue) - Passenger revenue yield per ASM, calculated as passenger revenue divided by available seat miles. Also referred to as “passenger unit revenues,” this is a measure of passenger revenue production based on the total available seat miles flown during a particular period.
(i) CASM (unit costs) - Operating expenses per ASM, calculated as operating expenses divided by available seat miles. Also referred to as "unit costs" or "cost per available seat mile," this is the average cost to fly an aircraft seat (empty or full) one mile, which is a measure of cost efficiencies.

As of January 1, 2018, the Company adopted three Accounting Standard Updates ("ASUs"), ASU 2014-09, Revenue from Contracts with Customers, ASU 2017-07, Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, and ASU 2017-12, Targeted Improvements to Accounting for Hedging Activities. As a result certain prior period results have been recast due to the transition methods applied. See the Company's Current Report on Form 8-K furnished to the Securities and Exchange Commission on March 20, 2018, as well as subsequent filings, for further information.

(a) Net adjustment related to presumption that all aircraft in fleet are owned (i.e., the impact of eliminating aircraft rent expense and replacing with estimated depreciation expense for those same aircraft). The Company makes this adjustment to enhance comparability to other entities that have different capital structures by utilizing alternative financing decisions.
(b) Calculated as an average of the five most recent quarter end balances or remaining obligations. The Net present value of aircraft operating leases represents the assumption that all aircraft in the Company’s fleet are owned, as it reflects the remaining contractual commitments discounted at the Company's estimated incremental borrowing rate as of the time each individual lease was signed.     
(c) The Equity adjustment for hedge accounting in the denominator adjusts for the cumulative impacts, in Accumulated other comprehensive income and Retained earnings, of gains and/or losses associated with hedge





accounting related to fuel hedge derivatives that will settle in future periods. The current period impact of these gains and/or losses is reflected in the Net impact from fuel contracts in the numerator.
(d) As the twelve month rolling tax rate no longer approximates an annual tax rate due to the significant impact the Tax Cuts and Jobs Act legislation enacted in December 2017 had on corporate tax rates, the Company is utilizing the 2018 year-to-date tax rate for 2018 ROIC, after-tax. The 2018 year-to-date GAAP tax rate was 22.8 percent, and the Non-GAAP tax rate for the period was also 22.8 percent. Utilizing the Company’s tax rate based on Operating income, non-GAAP for the twelve months ended September 30, 2018, of 25.7 percent, Non-GAAP ROIC, after tax, would have been 17.4 percent. See Note Regarding Use of Non-GAAP Financial Measures for additional information. For full year 2018, the Company estimates its effective tax rate to be approximately 23 percent.
(e) The GAAP twelve month rolling tax rate as of September 30, 2017, was 36.1 percent, and the twelve month rolling Non-GAAP tax rate was also 36.1 percent. See Note Regarding Use of Non-GAAP Financial Measures for additional information.

NOTE REGARDING USE OF NON-GAAP FINANCIAL MEASURES
The Company's unaudited Condensed Consolidated Financial Statements are prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). These GAAP financial statements include (i) unrealized noncash adjustments and reclassifications, which can be significant, as a result of accounting requirements and elections made under accounting pronouncements relating to derivative instruments and hedging and (ii) other charges and benefits the Company believes are unusual and/or infrequent in nature and thus may make comparisons to its prior or future performance difficult.
As a result, the Company also provides financial information in this release that was not prepared in accordance with GAAP and should not be considered as an alternative to the information prepared in accordance with GAAP. The Company provides supplemental non-GAAP financial information (also referred to as "excluding special items"), including results that it refers to as "economic," which the Company's management utilizes to evaluate its ongoing financial performance and the Company believes provides additional insight to investors as supplemental information to its GAAP results. The non-GAAP measures provided that relate to the Company’s performance on an economic fuel cost basis include Fuel and oil expense, non-GAAP; Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding profitsharing and Fuel and oil expense; Operating income, non-GAAP; Adjusted operating income, non-GAAP; Operating margin, non-GAAP; Other (gains) losses, net, non-GAAP; Income tax rate, non-GAAP; 12 month rolling income tax rate, non-GAAP; Net income, non-GAAP; Net margin, non-GAAP; and Net income per share, diluted, non-GAAP. The Company's economic Fuel and oil expense results differ from GAAP results in that they only include the actual cash settlements from fuel hedge contracts - all reflected within Fuel and oil expense in the period of settlement. Thus, Fuel and oil expense on an economic basis has historically been utilized by the Company, as well as some of the other airlines that utilize fuel hedging, as it reflects the Company’s actual net cash outlays for fuel during the applicable period, inclusive of settled fuel derivative contracts. Any net premium costs paid related to option contracts that are designated as hedges are reflected as a component of Fuel and oil expense, for both GAAP and non-GAAP (including economic) purposes in the period of contract settlement. The Company believes these economic results provide further insight on the impact of the Company's fuel hedges on its operating performance and liquidity since they exclude the unrealized, noncash adjustments and reclassifications that are recorded in GAAP results in accordance with accounting guidance relating to derivative instruments, and they reflect all cash settlements related to fuel derivative contracts within Fuel and oil expense. This enables the Company's management, as well as investors and analysts, to consistently assess the Company's operating performance on a year-over-year or quarter-over-quarter basis after considering all efforts in place to manage fuel expense. However, because these measures are not determined in accordance with GAAP, such measures are susceptible to varying calculations, and not all companies calculate the measures in the same manner. As a result, the aforementioned measures, as presented, may not be directly comparable to similarly titled measures presented by other companies.

Further information on (i) the Company's fuel hedging program, (ii) the requirements of accounting for derivative instruments, and (iii) the causes of hedge ineffectiveness and/or mark-to-market gains or losses from derivative instruments is included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017, as well as its Current Report on Form 8-K furnished to the Securities and Exchange Commission on March 20, 2018, and subsequent filings.
The Company’s GAAP results in the applicable periods include other charges or benefits that are also deemed “special items,” that the Company believes make its results difficult to compare to prior periods, anticipated future periods, or industry trends. Financial measures identified as non-GAAP (or as excluding special items) have been adjusted to exclude special items. Special items include:

1.
Lease termination costs recorded as a result of the Company acquiring 13 of its Boeing 737-300 aircraft off operating leases as part of the Company's strategic effort to remove its Classic aircraft from operations on or before September 29, 2017, in the most economically advantageous manner possible. The Company had not budgeted for these early lease termination costs, as they were subject to negotiations being concluded with the third party lessors. The Company recorded the fair value of the aircraft acquired off operating leases, as well as any associated remaining obligations to the balance sheet as debt;
2.
An Aircraft grounding charge recorded in third quarter 2017, as a result of the Company grounding its remaining Boeing 737-300 aircraft on September 29, 2017. The loss was a result of the remaining net lease payments due and certain lease return requirements that could have to be performed on these





leased aircraft prior to their return to the lessors as of the cease-use date. The Company had not budgeted for the lease return requirements, as they were subject to negotiation with third party lessors; and
3.
A gain recognized in first quarter 2018, associated with the sale of 39 owned Boeing 737–300 aircraft and a number of spare engines, to a third party. These aircraft were previously retired as part of the Company's exit of its Classic fleet. The gain was not anticipated, and the Company associates it in conjunction with the grounding charge recorded in third quarter 2017.

Because management believes each of these items can distort the trends associated with the Company’s ongoing performance as an airline, the Company believes that evaluation of its financial performance can be enhanced by a supplemental presentation of results that exclude the impact of these items in order to enhance consistency and comparativeness with results in prior periods that do not include such items and as a basis for evaluating operating results in future periods. The following measures are often provided, excluding special items, and utilized by the Company’s management, analysts, and investors to enhance comparability of year-over-year results, as well as to industry trends: Total operating expenses, non-GAAP; Operating expenses, non-GAAP excluding Fuel and oil expense; Operating expenses, non-GAAP excluding profitsharing and Fuel and oil expense; Operating income, non-GAAP; Adjusted operating income, non-GAAP; Operating margin, non-GAAP; Other (gains) losses, net, non-GAAP; Income tax rate, non-GAAP; 12 month rolling income tax rate, non-GAAP; Net income, non-GAAP; Net margin, non-GAAP; and Net income per share, diluted, non-GAAP.

The Company has also provided free cash flow, which is a non-GAAP financial measure. The Company believes free cash flow is a meaningful measure because it demonstrates the Company's ability to service its debt, pay dividends, and make investments to enhance Shareholder value. Although free cash flow is commonly used as a measure of liquidity, definitions of free cash flow may differ; therefore, the Company is providing an explanation of its calculation for free cash flow. For the three months ended September 30, 2018, the Company generated $817 million in free cash flow, calculated as operating cash flows of $1.3 billion less capital expenditures of $454 million less assets constructed for others of $8 million plus reimbursements for assets constructed for others of $8 million. For the nine months ended September 30, 2018, the Company generated $2.6 billion in free cash flow, calculated as operating cash flows of $3.9 billion less capital expenditures of $1.4 billion less assets constructed for others of $49 million plus reimbursements for assets constructed for others of $165 million.

The Company has also provided its calculation of return on invested capital, which is a measure of financial performance used by management to evaluate its investment returns on capital. Return on invested capital is not a substitute for financial results as reported in accordance with GAAP, and should not be utilized in place of such GAAP results. Although return on invested capital is not a measure defined by GAAP, it is calculated by the Company, in part, using non-GAAP financial measures. Those non-GAAP financial measures are utilized for the same reasons as those noted above for Net income, non-GAAP and Operating income, non-GAAP - the comparable GAAP measures include charges or benefits that are deemed “special items” that the Company believes make its results difficult to compare to prior periods, anticipated future periods, or industry trends, and the Company’s profitability targets and estimates, both internally and externally, are based on non-GAAP results since in the vast majority of cases the “special items” cannot be reliably predicted or estimated. The Company believes non-GAAP return on invested capital is a meaningful measure because it quantifies the Company's effectiveness in generating returns relative to the capital it has invested in its business. Although return on invested capital is commonly used as a measure of capital efficiency, definitions of return on invested capital differ; therefore, the Company is providing an explanation of its calculation for non-GAAP return on invested capital in the accompanying reconciliation, in order to allow investors to compare and contrast its calculation to those provided by other companies.
