NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

Note A — Condensed Consolidated Financial Statements

The condensed consolidated financial statements of SkyWest, Inc. (“SkyWest” or the “Company”) and its wholly-owned subsidiaries, SkyWest Airlines, Inc. (“SkyWest Airlines”) and Atlantic Southeast Airlines, Inc. (“Atlantic Southeast”) included herein have been prepared, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations, although SkyWest believes that the following disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements reflect all adjustments that, in the opinion of management, are necessary to present fairly the results of operations for the interim periods presented. All adjustments are of a normal recurring nature, unless otherwise disclosed. The Company suggests that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2009.  The results of operations for the three and nine month periods ended September 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results will differ and may differ materially from those estimates and assumptions.

Note B — Merger and Related Matters

On August 3, 2010, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ExpressJet Holdings, Inc. (“ExpressJet”) and Express Delaware Merger Co., a wholly-owned subsidiary of Atlantic Southeast (“Express Merger Co.”), pursuant to which Atlantic Southeast proposes to acquire ExpressJet.  The Merger Agreement provides for the merger of Express Merger Co. and ExpressJet, with ExpressJet becoming a wholly-owned subsidiary of Atlantic Southeast (the “Merger”).  If the Merger is completed as contemplated by the Merger Agreement, the ExpressJet stockholders will receive $6.75 in cash for each outstanding share of ExpressJet common stock, and the net acquisition price for all of the issued and outstanding shares of ExpressJet common stock (after giving effect to shares of ExpressJet common stock presently owned by Atlantic Southeast) would be approximately $133 million.  In connection with the proposed transaction, the Company has negotiated the terms of an amended capacity purchase agreement between ExpressJet and Continental Airlines, Inc., which the Company anticipates will become effective if the Merger is completed.  Completion of the Merger is subject to approval by ExpressJet’s stockholders, regulatory approvals and other customary closing conditions, and is currently expected to occur during the fourth quarter of 2010.

Note C — New Accounting Pronouncements

On September 23, 2009, the Financial Accounting Standards Board (“FASB”) ratified Emerging Issues Task Force Issue No. 08-1, Revenue Arrangements with Multiple Deliverables (“EITF 08-1”). EITF 08-1 updates the current guidance pertaining to multiple-element revenue arrangements included in ASC Subtopic 605-25, which originated primarily from EITF 00-21, also titled Revenue Arrangements with Multiple Deliverables. EITF 08-1 will be effective for annual reporting periods beginning January 1, 2011 for calendar-year entities. The Company is currently evaluating the impact of EITF 08-1 on its financial position, results of operations, cash flows, and disclosures.

Note D — Passenger and Ground Handling Revenue

The Company recognizes passenger and ground handling revenues when the service is provided. Under the Company’s contract and pro-rate flying agreements with Delta Air Lines, Inc. (“Delta”), United Air Lines, Inc. (“United”) and AirTran Airways, Inc. (“AirTran”), revenue is considered earned when the flight is completed. Revenue is recognized under the Company’s pro-rate flying agreements based upon the portion of the pro-rate passenger fare the Company anticipates that it will receive.

SkyWest Airlines and Atlantic Southeast have each entered into a Delta Connection Agreement with Delta, pursuant to which SkyWest Airlines and Atlantic Southeast provide contract flight services for Delta.  The Delta Connection Agreements provide for fifteen-year terms, subject to early termination by Delta, SkyWest Airlines or Atlantic Southeast, as applicable, upon the occurrence of certain events. Delta’s termination rights include (i) cross-termination rights between the two Delta Connection Agreements, (ii) the

7

Table of Contents

right to terminate each of the Delta Connection Agreements upon the occurrence of certain force majeure events, including certain labor-related events, that prevent SkyWest Airlines or Atlantic Southeast from performance for certain periods, and (iii) the right to terminate each of the Delta Connection Agreements if SkyWest Airlines or Atlantic Southeast fails to maintain competitive base rate costs, subject to certain adjustment rights. The SkyWest Airlines and Atlantic Southeast Delta Connection Agreements contain multi-year rate reset provisions beginning in 2010 and each 5th year thereafter. In the Delta Connection Agreements, the fixed-fee rates are specifically defined through 2009. The parties agreed that on or after a specified date in 2010 the parties would reset such rates to reflect SkyWest Airlines’ actual costs in 2010 (with a similar process on each 5th year thereafter). In addition to the termination rights, Delta has the right to extend the term of the Delta Connection Agreements upon the occurrence of certain events or at the expiration of the initial term. SkyWest Airlines and Atlantic Southeast have the right to terminate their respective Delta Connection Agreement upon the occurrence of certain breaches by Delta, including the failure to cure payment defaults. SkyWest Airlines and Atlantic Southeast also have cross-termination rights between the two Delta Connection Agreements.

Under the terms of the SkyWest Airlines Delta Connection Agreement, Delta has agreed to compensate SkyWest Airlines for the direct costs associated with operating the Delta Connection flights, plus a payment based on block hours flown. Under the terms of the Atlantic Southeast Delta Connection Agreement, Delta has agreed to compensate Atlantic Southeast for its direct costs associated with operating the Delta Connection flights, plus, if Atlantic Southeast completes a certain minimum percentage of its Delta Connection flights, an additional percentage of such costs. Additionally, Atlantic Southeast’s Delta Connection Agreement provides for the payment of incentive compensation upon satisfaction of certain performance goals. The incentives are defined in the Atlantic Southeast Delta Connection Agreement as being measured and determined on a monthly and quarterly basis. At the end of each quarter, the Company calculates the incentives achieved during the quarter and recognizes revenue accordingly. The parties to the Delta Connection Agreements made customary representations, warranties and covenants, including with respect to various operational, marketing and administrative matters.

In the event that the contractual rates under the Delta Connection Agreements have not been finalized at quarterly or annual financial statement dates, the Company records revenues based on the lower of prior period’s approved rates, as adjusted to reflect any contract negotiations and the Company’s estimate of rates that will be implemented in accordance with revenue recognition guidelines. Among other provisions, the Delta Connection Agreements provide that, beginning with the third anniversary of the execution of the agreements (September 8, 2008), Delta has the right to require that certain contractual rates under those agreements shall not exceed the average rate of all carriers within the Delta Connection Program. On October 23, 2009, Delta sent letters to SkyWest Airlines and Atlantic Southeast requiring them to either adjust the rates payable under their respective Delta Connection Agreements or accept termination of those agreements. Delta’s letters also notified SkyWest Airlines and Atlantic Southeast of Delta’s estimate of the average rates to be applied under those agreements. On October 28, 2009, SkyWest Airlines and Atlantic Southeast notified Delta of their election to adjust the rates payable under the Delta Connection Agreements; however, they also notified Delta of their disagreement with Delta’s estimated rates and their belief that the methodology Delta used to calculate its estimated rates is inconsistent with the terms of the Delta Connection Agreements. SkyWest Airlines and Atlantic Southeast, on one hand, and Delta, on the other hand, have exchanged subsequent correspondence, and SkyWest Airlines and Atlantic Southeast continue to negotiate with Delta in an effort to determine an appropriate methodology for calculating the average rates of the carriers within the Delta Connection Program.

The Delta Connection Agreements also provide that, beginning with the fifth anniversary of the execution of the agreements (September 8, 2010), Delta has the right to require that certain contractual rates under those agreements shall not exceed the second lowest of all carriers within the Delta Connection Program. On September 8, 2010, Delta sent letters to SkyWest Airlines and Atlantic Southeast requiring them to either adjust the rates payable under their respective Delta Connection Agreements or accept termination of those agreements. Delta’s letters also notified SkyWest Airlines and Atlantic Southeast of Delta’s estimate of the second lowest rates to be applied under those agreements. On September 10, 2010, SkyWest Airlines and Atlantic Southeast notified Delta of their election to adjust the rates payable under the Delta Connection Agreements; however, they also notified Delta of their disagreement with Delta’s estimated rates and their belief that the methodology Delta used to calculate its estimated rates is inconsistent with the terms of the Delta Connection Agreements. SkyWest Airlines and Atlantic Southeast, on one hand, and Delta, on the other hand, have exchanged subsequent correspondence, and SkyWest Airlines and Atlantic Southeast continue to negotiate with Delta in an effort to determine an appropriate methodology for calculating the second lowest rates of the carriers within the Delta Connection Program. Because SkyWest Airlines and Atlantic Southeast have not reached an agreement with Delta regarding the final contractual rates to be established under the Delta Connection Agreements, the Company has evaluated the method for calculating the average rates and the second lowest rates of the carriers within the Delta Connection Program under the revenue recognition accounting guidance. The Company has recorded revenue under those agreements based on management’s understanding of the applicable terms in the Delta Connection Agreements and management’s best estimate of the revenue that will ultimately be realized upon settlement of the contractual rates with Delta with respect to the three and nine months ended September 30, 2010.

In the event the Company has a reimbursement dispute with a major partner, the Company evaluates the dispute under its established revenue recognition criteria and, provided the revenue recognition criteria have been met, the Company recognizes

8

Table of Contents

revenue based on management’s estimate of the resolution of the dispute. During the quarter ended December 31, 2007, Delta notified the Company, SkyWest Airlines and Atlantic Southeast of a dispute under the Delta Connection Agreements executed by Delta with SkyWest Airlines and Atlantic Southeast. The dispute relates to allocation of liability for certain irregular operations (“IROP”) expenses that are paid by SkyWest Airlines and Atlantic Southeast to their passengers under certain situations. As a result, Delta withheld a combined total of approximately $25 million (pretax) from one of the weekly scheduled wire payments to SkyWest Airlines and Atlantic Southeast during December 2007. Delta continues to withhold a portion of the funds the Company believes are payable as weekly scheduled wire payments to SkyWest Airlines and Atlantic Southeast (See Note M for additional details).

SkyWest Airlines and United have entered into a United Express Agreement, which sets forth the principal terms and conditions governing SkyWest Airlines’ United Express operations. Under the terms of the United Express Agreement, SkyWest Airlines is compensated primarily on a fee-per-completed-block hour and departure basis and is reimbursed for fuel and other costs. Additionally, SkyWest Airlines is eligible for incentive compensation upon the achievement of certain performance criteria. The incentives are defined in the United Express Agreement as being measured and determined on a monthly basis. At the end of each month, the Company calculates the incentives achieved during the month and recognizes revenue accordingly.

On February 10, 2010, Atlantic Southeast and United entered into a United Express Agreement, pursuant to which Atlantic Southeast agreed to operate 14 Bombardier CRJ200 (“CRJ200”) regional jet aircraft  as a United Express carrier.  On February 11, 2010, Atlantic Southeast began operating as a United Express carrier. The Atlantic Southeast United Express Agreement is a capacity purchase agreement with a five-year term, and other terms which are generally consistent with the SkyWest Airlines United Express Agreement.  During the three months ended September 30, 2010, Atlantic Southeast agreed to add two CRJ200s to the United Express Agreement on a short term basis. As of September 30, 2010, Atlantic Southeast was operating 16 CRJ 200s as a United Express carrier.

On November 4, 2009, SkyWest Airlines entered into a code-share agreement with AirTran. Under the terms of the code-share agreement, SkyWest Airlines operates four CRJ200s for AirTran under a pro-rate arrangement. SkyWest Airlines commenced AirTran service in December 2009. The code-share agreement has a three-year term; however, after May 15, 2010, either party may terminate the agreement upon 120 days written notice.

The Company’s passenger and ground handling revenues could be impacted by a number of factors, including changes to the Company’s code-share agreements with Delta, United or AirTran, consummation of the proposed Merger contract modifications resulting from contract re-negotiations, the Company’s ability to earn incentive payments contemplated under the Company’s code-share agreements, settlement of reimbursement disputes with the Company’s major partners and settlement of the Delta rates.

Note E — Share-Based Compensation

The fair value of stock options granted by the Company has been estimated as of the grant date using the Black-Scholes option pricing model. During the nine months ended September 30, 2010 the Company granted options to purchase 320,458 shares of common stock under the SkyWest, Inc. 2006 Long-Term Incentive Plan (the “2006 Incentive Plan”).  The following table shows the assumptions used and weighted average fair value for stock option grants during the nine months ended September 30, 2010.

During the nine months ended September 30, 2010, the Company granted 220,779 restricted stock units to employees of the Company and its subsidiaries under the 2006 Incentive Plan.  The restricted stock units have a three-year vesting period, during which the recipient must remain employed with the Company or one of the Company’s subsidiaries.  Upon vesting, a restricted stock unit will be replaced with a share of the Company’s common stock. Additionally, during the nine months ended September 30, 2010, the Company granted 27,605 fully-vested shares of common stock to the Company’s directors.  The weighted average fair value of the shares of restricted stock on the date of grant was $14.49 per share.

The Company records share-based compensation expense only for those options and restricted stock units that are expected to vest.  The estimated fair value of the stock options and restricted stock units is amortized over the applicable vesting periods.  During the three months ended September 30, 2010 and 2009, the Company recorded pre-tax share-based compensation expense of $1.5 million and $1.7 million, respectively. During the nine months ended September 30, 2010 and 2009, the Company recorded pre-tax share-based compensation expense of $5.0 million and $6.2 million, respectively.

Note F — Net Income Per Common Share

Basic net income per common share (“Basic EPS”) excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted net income per common share (“Diluted EPS”) reflects the

9

Table of Contents

potential dilution that could occur if stock options or other contracts to issue common stock were exercised or converted into common stock. The computation of Diluted EPS does not assume exercise or conversion of securities that would have an anti-dilutive effect on net income per common share. During the three months ended September 30, 2010 and 2009 options to acquire 4,315,000 and 4,334,000 shares, respectively, were excluded from the computation of Diluted EPS as their impact was anti-dilutive. During the nine months ended September 30, 2010 and 2009 options to acquire 4,403,000 and 4,390,000 shares, respectively, were excluded from the computation of Diluted EPS as their impact was anti-dilutive.

The calculation of the weighted average number of common shares outstanding for Basic EPS and Diluted EPS for the periods indicated (in thousands, except per share data) is as follows:

Note G — Comprehensive Income

Comprehensive income includes charges and credits to stockholders’ equity that are not the result of transactions with stockholders. Also, comprehensive income consists of net income plus changes in unrealized appreciation (depreciation) on marketable securities and unrealized gain (loss) on foreign currency translation adjustment related to the Company’s equity investment in Trip Linhas Aereas (“Trip”), net of tax, for the periods indicated (in thousands):

Note H — Long-Term Debt

Long-term debt of the Company consisted of the following for the periods indicated (in thousands):

10

Table of Contents

At September 30, 2010, the three-month and six-month LIBOR rates were 0.29% and 0.46%, respectively.   At December 31, 2009, the three-month and six-month LIBOR rates were 0.25% and 0.43%, respectively.

Note I — Commitments and Contingencies

As of September 30, 2010, the Company leased 293 aircraft, as well as airport facilities, office space, and various other property and equipment under non-cancelable operating leases which are generally on a long-term net rent basis where the Company pays taxes, maintenance, insurance and certain other operating expenses applicable to the leased property.  The Company expects that, in the normal course of business, leases that expire will be renewed or replaced by other leases.  The following table summarizes future minimum rental payments required under operating leases that had initial or remaining non-cancelable lease terms in excess of one year as of September 30, 2010 (in thousands):

Note J — Fair Value Measurements

The Company holds certain assets that are required to be measured at fair value in accordance with United States GAAP. The Company determined fair value of these assets based on the following three levels of inputs:

As of September 30, 2010, the Company held certain assets that are required to be measured at fair value on a recurring basis. The Company has invested in auction rate security instruments, which are classified as available for sale securities and reflected at fair value. However, due primarily to credit market events beginning during the first quarter of 2008, the auction events for most of these instruments failed. Therefore, quoted prices in active markets are no longer available and the Company has estimated the fair values of these securities utilizing a discounted cash flow analysis as of September 30, 2010. These analyses consider, among other items, the collateralization underlying the security investments, the creditworthiness of the counterparty, the timing of expected future cash flows, and the expectation of the next time the security is expected to have a successful auction.

As of September 30, 2010, the Company owned $4.3 million of auction rate security instruments. The auction rate security instruments held by the Company at September 30, 2010 were tax-exempt municipal bond investments, for which the market has experienced some successful auctions. The Company has classified the investments as non-current and has identified them as “Other assets” in its unaudited Condensed Consolidated Balance Sheet as of September 30, 2010. The Company has classified these securities

11

Table of Contents

as non-current due to the Company’s belief that the market for these securities may take in excess of twelve months to fully recover. As of September 30, 2010, the Company continued to record interest on all of its auction rate security instruments. Any future fluctuations in fair value related to these instruments that the Company deems to be temporary, including any recoveries of previous write downs, would be recorded to accumulated other comprehensive income. If the Company determines that any future valuation adjustment was other than temporary, a charge would be recorded to earnings as appropriate.

As of September 30, 2010, the Company held certain assets that are required to be measured at fair value on a recurring basis. Assets measured at fair value on a recurring basis are summarized below (in thousands):

(a)         Auction rate securities included in “Other assets” in the unaudited Consolidated Balance Sheet

Based on market conditions, the Company uses a discounted cash flow valuation methodology for auction rate securities. Accordingly, for purposes of the foregoing condensed consolidated financial statements, these securities were categorized as Level 3 securities. The Company’s “Marketable Securities” classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities.

No significant transfers between Level 1, Level 2 and Level 3 occurred during the three and nine months ended September 30, 2010.  The Company’s policy regarding the recording of transfers between levels is to record any such transfers at the end of the reporting period.

The following table presents the Company’s assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at September 30, 2010 (in thousands):

Fair Value Measurements Using Significant Unobservable Inputs

(Level 3)

The fair value of the Company’s long-term debt is estimated based on current rates offered to the Company for similar debt and was estimated to be $2,105.0 million as of September 30, 2010, as compared to the carrying amount of $1,943.0 million as of September 30, 2010.

Note K — Investment in Other Companies

In September  2008, the Company entered into an agreement to acquire a 20% interest in Trip. During the nine months ended September 30, 2010, the Company invested an additional $10 million in Trip. As of September 30, 2010, the Company’s investment balance in Trip was $32.1 million, which represents a 20% ownership interest and is recorded as an “Other asset” on the Company’s consolidated balance sheet. The Company accounts for its interest in Trip using the equity method of accounting. The Company records its equity in Trip’s earnings on a one-quarter lag. The Company’s portion of Trip’s loss for the three and nine months ended September 30, 2010 was $0.2 million and $1.6 million, respectively.

12

Table of Contents

On September 29, 2010, the Company invested $7 million for a 30% ownership interest in Mekong Aviation Joint Stock Company, an airline operating in Vietnam (“Air Mekong”). The Company’s investment in Air Mekong  is recorded as an “Other asset” on the Company’s consolidated balance sheet.  The Company anticipates accounting for the investment using the equity method of accounting and intends to reflect its equity interest in Air Mekong’s earnings on a one-quarter lag.

Note L — Note Receivable

On October 16, 2009, SkyWest Airlines extended to United a secured term loan in the amount of $80 million. The term loan bore interest at a rate of 11%, with a ten-year amortization period. The loan was secured by certain ground equipment and airport slot rights held by United. On August 11, 2010, United repaid the $80 million term loan.

Note M — Legal Matters

The Company is subject to certain legal actions which it considers routine to its business activities. As of September 30, 2010, management believes, after consultation with legal counsel, that the ultimate outcome of such legal matters is not likely to have a material adverse effect on the Company’s financial position, liquidity or results of operations. However, the following are significant outstanding legal matters, which, if not resolved consistent with the position taken by the Company, would negatively impact the Company’s financial results.

Atlantic Southeast and SkyWest Airlines v. Delta

During the quarter ended December 31, 2007, Delta notified the Company, SkyWest Airlines and Atlantic Southeast of a dispute under the Delta Connection Agreements executed by Delta with SkyWest Airlines and Atlantic Southeast. The dispute relates to allocation of liability for IROP expenses that are paid by SkyWest Airlines and Atlantic Southeast to their passengers and vendors under certain situations. As a result, Delta withheld a combined total of approximately $25 million (pretax) from one of the weekly scheduled wire payments to SkyWest Airlines and Atlantic Southeast during December 2007. Delta continues to withhold a portion of the funds the Company believes are payable as weekly scheduled wire payments to SkyWest Airlines and Atlantic Southeast. As of June 30, 2008, the Company had recognized a cumulative total of $31.7 million of revenue associated with the funds withheld by Delta. Since July 1, 2008, the Company has not recognized revenue related to IROP expense reimbursements withheld by Delta because collection of those reimbursements is the subject of litigation (summarized below) and is therefore not reasonably assured. On February 1, 2008, SkyWest Airlines and Atlantic Southeast filed a lawsuit in Georgia state court disputing Delta’s treatment of the matter (the “Complaint”). Delta filed an Answer to the Complaint and a Counterclaim against SkyWest Airlines and Atlantic Southeast on March 24, 2008. Delta’s Counterclaim alleges that Atlantic Southeast and SkyWest Airlines breached the Delta Connection Agreements by invoicing Delta for the IROP expenses that were paid pursuant to Delta’s policies, and claims only a portion of those expenses may be invoiced to Delta. Delta seeks unspecified damages in its counterclaim.

On March 24, 2008, Delta filed a Motion to Dismiss the Complaint (the “Motion to Dismiss”). A hearing on the Motion to Dismiss was held September 5, 2008. In an order entered September 13, 2008, the Court granted in part and denied in part the Motion to Dismiss. The Court denied the Motion to Dismiss with respect to the breach of contract claim contained in the Complaint. The Court denied in part the Motion to Dismiss with respect to the action for declaratory judgment contained in the Complaint, and granted in part the Motion to Dismiss to the extent the Complaint seeks to read alternative or supplemental obligations created by prior conduct into the Delta Connection Agreements. The Court granted the Motion to Dismiss with respect to claims for estoppel, unilateral mistake, and mutual mistake contained in the Complaint. The breach of contract claims and declaratory relief claims were not dismissed.

On July 31, 2009, SkyWest Airlines and Atlantic Southeast filed an Amended Complaint in the lawsuit adding claims under Georgia law for voluntary payment and mutual departure from the strict terms of the Delta Connection Agreements. Under those claims, SkyWest Airlines and Atlantic Southeast seek recovery of all of the approximately $25 million withheld by Delta during December 2007. SkyWest Airlines and Atlantic Southeast are also seeking recovery of additional amounts withheld by Delta subsequent to December 2007. Discovery on SkyWest Airlines’ and Atlantic Southeast’s claims and defenses has not yet been completed. On September 4, 2009, Delta filed a motion to dismiss the Amended Complaint in part. Delta asserted that the claims added by SkyWest Airlines and Atlantic Southeast in the Amended Complaint should be dismissed based on legal arguments set forth in Delta’s memorandum in support of its motion. SkyWest Airlines and Atlantic Southeast opposed the motion.  On January 22, 2010, the Court granted Delta’s motion in part, dismissing the claims under Georgia law for voluntary payment and mutual departure from the strict terms of the Connection Agreements. SkyWest Airlines and Atlantic Southeast continue to vigorously pursue their claims set forth in the Amended Complaint, to the extent permitted by the Court’s ruling on the Motion to Dismiss, and their defenses to Delta’s counterclaims.  The Court’s rulings affect the current posture of the case, but do not preclude pursuit of the claims for breach of contract or for declaratory relief, under which SkyWest Airlines and Atlantic Southeast continue to seek recovery of the majority of the amounts withheld by Delta.

ExpressJet Stockholder Litigation

Between August 5, 2010 and August 25, 2010, nine substantially similar putative shareholder class action suits (collectively, the “Texas State Actions”) were filed by individual ExpressJet stockholders in the District Court of Harris County, Texas against ExpressJet and its directors.  Many of the petitions also name the Company, Atlantic Southeast and/or Express Merger Co. (together, the “SkyWest Defendants”) as defendants in the litigation.

The petitions filed in the Texas State Actions generally allege that the ExpressJet director defendants breached their fiduciary duties in connection with the negotiations and approval of the Merger Agreement and that the SkyWest Defendants aided and abetted such alleged breaches of fiduciary duties.  The Texas State Actions seek, among other things, an injunction enjoining the Merger and the transactions contemplated by the Merger Agreement and rescission of any transactions contemplated by the Merger Agreement which may be completed.  On August 18, 2010, plaintiff Rayside filed a motion to consolidate the Texas State Actions into Case No. 2010-48784 in the first-filed court (the “189th District Court).  On August 20, 2010, plaintiffs Levine, Tejeda, Doraiswamy and Swanepoel filed a similar motion in the 189th District Court.  On September 10, 2010, the 189th District Court ordered the consolidation of the Texas State Actions with and into Case No. 2010-48784 (the consolidated action is referred to herein as the “Consolidated Texas State Action”).

On September 20, 2010, a putative stockholder class action (the “Texas Federal Action” and, together with the Consolidated Texas State Action, the “Actions”) was commenced in the United States District Court for the Southern District of Texas, Houston Division.  The complaint filed in the Texas Federal Action includes substantially identical allegations to and requests substantially the same relief as the petitions in the Texas State Actions, but also includes allegations related to the ExpressJet preliminary proxy statement filed with the U. S. Securities and Exchange Commission on September 3, 2010.

On October 8, 2010, counsel for the defendants in the Actions, counsel for the plaintiff class in the Consolidated Texas State Action and counsel for plaintiff in the Texas Federal Action agreed to and executed a memorandum of understanding (the “MOU”) containing the terms of an agreement in principle to resolve the Actions.  The MOU provides that, in consideration for the settlement of the Actions, ExpressJet will make certain disclosures in the definitive proxy statement to be sent to the ExpressJet stockholders soliciting approval of the Merger.  In the MOU, the defendants in the Actions acknowledge that they considered the claims raised by the plaintiffs in the Actions in connection with the disclosures contemplated by the MOU.  In exchange, the parties to the MOU have agreed to use their best efforts to draft and execute a definitive stipulation of settlement that includes a plaintiff class consisting of all record and beneficial holders of ExpressJet stock, other than defendants in the Consolidated Texas State Action and any firm, trust, corporation or other entity controlled by any such defendant, during the period beginning on and including December 2, 2009, through and including the date of the consummation of the merger.  If approved by the parties and the 189th District Court, the settlement will result in the dismissal with prejudice of the Consolidated Texas State Action and release by the plaintiff class of all claims under federal and state law that were or could have been asserted in the Actions or which arise out of or relate to the transactions contemplated by the Merger.  The MOU further provides that, in the event the Consolidated Texas State Action is dismissed in accordance with the settlement stipulation, the parties to the MOU will use their best efforts to obtain the dismissal with prejudice of the Texas Federal Action.  The settlement of the Consolidated Texas State Action is subject to numerous conditions set forth in the MOU and to be contained in any stipulation of settlement, including the completion of the Merger.

For financial reporting purposes the Company accrues an estimated loss if the loss is probable and reasonably estimable. Because these conditions have not been satisfied with respect to the matters described above, the Company did not record a loss related such matters as of September 30, 2010.

Overview

Through SkyWest Airlines and Atlantic Southeast, we operate the largest regional airline in the United States. As of September 30, 2010, SkyWest Airlines and Atlantic Southeast offered scheduled passenger and air freight service with more than 2,800 total daily departures to 225 destinations in the United States, Canada, Mexico and the Caribbean. Additionally, as of September 30, 2010, we provided ground handling services for approximately 11 other airlines throughout our system. As of September 30, 2010, we had a combined fleet of 466 aircraft consisting of 258 50-seat Bombardier Aerospace (“Bombardier”) CRJ 200 Regional Jets (the “CRJ200”) (99 assigned to United Air Lines, Inc. (“United”), 150 assigned to Delta Air Lines, Inc. (“Delta”), four assigned to Air Tran Airways, Inc. (“AirTran”), three  used by SkyWest Airlines as additional maintenance spare aircraft  and two subleased to an un-affiliated entity) 125 70-seat Bombardier CRJ700 Regional Jets (the “CRJ700”)  (70 assigned to United and 55 assigned to Delta), 35 76-seat Bombardier CRJ900 Regional Jets (the “CRJ900”) (31 assigned to Delta and four subleased to an affiliated entity) and 48 30-seat Embraer Brasilia EMB-120 turboprop aircraft (the “Brasilia turboprop”) (35 assigned to United and 13 assigned to Delta). We believe our success in attracting multiple contractual relationships with our major airline partners is attributable to our delivery of high-quality customer service with an all cabin-class fleet at a competitive cost structure. For the three months ended September 30, 2010, approximately 49.7% of our aggregate capacity was operated under the United code, approximately 49.5% was operated under the Delta code and approximately 0.8% under the AirTran code.

SkyWest Airlines has been a code-share partner with Delta in Salt Lake City and United in Los Angeles since 1987 and 1997, respectively. In 1998, SkyWest Airlines expanded its relationship with United to provide service in Portland, Seattle/Tacoma, San Francisco and additional Los Angeles markets. In 2004, SkyWest Airlines expanded its United Express operations to provide service in Chicago. On November 4, 2009, SkyWest Airlines entered into a code-share agreement with AirTran.

As of September 30, 2010, SkyWest Airlines operated as a Delta Connection carrier in Salt Lake City, a United Express carrier in Los Angeles, San Francisco, Denver, Chicago and the Pacific Northwest, and an AirTran carrier in Milwaukee, operating more than 1,750 total daily flights.

Atlantic Southeast has been a code-share partner with Delta in Atlanta since 1984 and United since February 2010. As of September 30, 2010, Atlantic Southeast operated as a Delta Connection carrier in Atlanta and Cincinnati and a United Express carrier in Chicago and Washington, D.C.  (Dulles International Airport), operating approximately 900 daily flights.

We provide a substantial majority of the regional airline service for Delta in Atlanta and Salt Lake City. In connection with our acquisition of Atlantic Southeast in September 2005, we established new, separate, but substantially similar, long-term fixed-fee Delta Connection Agreements with Delta for both SkyWest Airlines and Atlantic Southeast. We also obtained the right to use 29 gates in the Hartsfield-Jackson International Airport located in Atlanta, from which we currently provide service to Delta. Pursuant to the terms of the Delta Connection Agreement executed by Atlantic Southeast and Delta, Delta has also agreed that if Delta solicits requests for proposals to fly Delta Connection regional aircraft, Atlantic Southeast will be permitted to bid to maintain the same percentage of total Delta Connection regional jet flights that it operated during 2007, and, if Atlantic Southeast does not achieve the winning bid for the proposed flying, Atlantic Southeast will be permitted to match the terms of the winning bid to the extent necessary for Atlantic Southeast to maintain the same percentage of Delta Connection regional jet flights that it operated during 2007.

On February 10, 2010, Atlantic Southeast and United entered into a United Express Agreement, pursuant to which Atlantic Southeast agreed to operate 14 CRJ200 aircraft as a United Express carrier. As of September 30, 2010, 16 CRJ200s were operating under the Atlantic Southeast United Express Agreement.  The Atlantic Southeast United Express Agreement is a capacity purchase agreement with a five-year term, and other terms which are generally consistent with the SkyWest Airlines United Express Agreement.

Historically, multiple contractual relationships have enabled us to reduce reliance on any single major airline code and to enhance and stabilize operating results through a mix of contract flying and our controlled or “pro-rate” flying. For the three months ended September 30, 2010, contract flying revenue and pro-rate revenue represented approximately 88% and 12%, respectively, of our total passenger revenues. On contract routes, the major airline partner controls scheduling, ticketing, pricing and seat inventories and we are compensated by the major airline partner at contracted rates based on the completed block hours, flight departures and other operating measures. On pro-rate flights, we control scheduling, ticketing, pricing and seat inventories and receive a pro-rated portion of passenger fares. For the three months ended September 30, 2010, essentially all of our Brasilia turboprops flown for Delta were flown under pro-rate arrangements, while approximately 36% of our Brasilia turboprops flown in the United system were flown under contractual arrangements, with the remaining 64% flown under pro-rate arrangements. For the three months ended September 30, 2010, approximately 89% of our CRJ200s flown in the United system were flown under contractual arrangements, with the remaining 11% flown under pro-rate arrangements. On November 4, 2009, SkyWest Airlines entered into a code-share agreement with AirTran. Under the terms of the AirTran code-share agreement, SkyWest Airlines has agreed to operate four CRJ200s for AirTran under a pro-rate arrangement.

Third Quarter Summary

We had revenues of $686.9 million for the three months ended September 30, 2010, a 7.7% increase, compared to revenues of $637.7 million for the three months ended September 30, 2009. We had net income of $25.5 million, or $0.45 per diluted share, for the three months ended September 30, 2010, a decrease of 10.8%, compared to $28.6 million of net income, or $0.50 per diluted share, for the three months ended September 30, 2009.

The significant items affecting our financial performance during the three months ended September 30, 2010 are summarized below:

Under the Delta Connection Agreements, Delta has the right to require that certain contractual rates under those agreements shall not exceed the average rate of all carriers within the Delta Connection Program. On October 23, 2009, Delta sent letters to SkyWest Airlines and Atlantic Southeast requiring them to either adjust the rates payable under their respective Delta Connection Agreements or accept termination of those agreements. Delta’s letters also notified SkyWest Airlines and Atlantic Southeast of Delta’s estimate of the average rates to be applied under those agreements. On October 28, 2009, SkyWest Airlines and Atlantic Southeast notified Delta of their election to adjust the rates payable under the Delta Connection Agreements; however, they also notified Delta of their disagreement with Delta’s estimated rates and their belief that the methodology Delta used to calculate its estimated rates is inconsistent with the terms of the Delta Connection Agreements. SkyWest Airlines and Atlantic Southeast, on one hand, and Delta, on the other hand, have exchanged subsequent correspondence, and SkyWest Airlines and Atlantic Southeast continue to negotiate with Delta in an effort to determine an appropriate methodology for calculating the average rates of the carriers within the Delta Connection Program.

The Delta Connection Agreements also provide that, beginning with the fifth anniversary of the execution of the agreements (which is September 8, 2010), Delta has the right to require that certain contractual rates under those agreements shall not exceed the second lowest rates of all carriers within the Delta Connection Program. On September 8, 2010, Delta sent letters to SkyWest Airlines and Atlantic Southeast requiring them to either adjust the rates payable under their respective Delta Connection Agreements or accept

termination of those agreements. Delta’s letters also notified SkyWest Airlines and Atlantic Southeast of Delta’s estimate of the second lowest rates to be applied under those agreements. On September 10, 2010, SkyWest Airlines and Atlantic Southeast notified Delta of their election to adjust the rates payable under the Delta Connection Agreements; however, they also notified Delta of their disagreement with Delta’s estimated rates and their belief that the methodology Delta used to calculate its estimated rates is inconsistent with the terms of the Delta Connection Agreements. SkyWest Airlines and Atlantic Southeast, on one hand, and Delta, on the other hand, have exchanged subsequent correspondence, and SkyWest Airlines and Atlantic Southeast continue to negotiate with Delta in an effort to determine an appropriate methodology for calculating the second lowest rates of the carriers within the Delta Connection program. Because SkyWest Airlines and Atlantic Southeast have not reached an agreement with Delta regarding the final contractual rates to be established under the Delta Connection Agreements, we have evaluated the method for calculating the average rates and the second lowest rates of the carriers within the Delta Connection Program under the revenue recognition accounting guidance. We have recorded revenue under those agreements based on our management’s understanding of the applicable terms in the Delta Connection Agreements and our management’s best estimate of the revenue that will ultimately be realized upon settlement of the contractual rates with Delta with respect to the three months ended September 30, 2010.  As a result of the average rate and second lowest rate provisions, our passenger revenues decreased $4.9 million during the three months ended September 30, 2010, compared to the three months ended September 30, 2009.

Under the SkyWest Airlines and Atlantic Southeast United Express Agreements, we recognize revenue in our condensed consolidated statement of income at a fixed hourly rate for mature engine maintenance on regional jet engines and we recognize engine maintenance expense on our CRJ200 regional jet engines in our condensed consolidated statement of income on an as-incurred basis as maintenance expense. During the three months ended September 30, 2010, our CRJ200 engine expense under our SkyWest Airlines and Atlantic Southeast United Express Agreements and our Airtran code-share agreement increased $2.1 million compared to the three months ended September 30, 2009.  The increase in CRJ 200 engine overhauls reimbursed at a fixed hourly rate was principally due to scheduled engine maintenance events.  We anticipate the average quarterly number of scheduled engine maintenance events we experienced during the three months ended September 30, 2010 will likely continue each quarter through 2010, 2011 and the first quarter of 2012.

Total available seat miles (“ASMs”) for the three months ended September 30, 2010 increased 6.4%, compared to the three months ended September 30, 2009, primarily due to SkyWest Airlines’ acceptance of 18 new CRJ700s since April 1, 2009 and its incremental placement of those aircraft into service over that period.  During the three months ended September 30, 2010, we generated 6.3 billion ASMs, compared to 5.9 billion ASMs during the three months ended September 30, 2009.

On August 3, 2010, we entered into the Merger Agreement with ExpressJet and Express Merger Co., a wholly-owned subsidiary of Atlantic Southeast.  The Merger Agreement provides for the merger of Express Merger Co. and ExpressJet, with ExpressJet becoming a wholly-owned subsidiary of Atlantic Southeast (the “Merger”).  If the Merger is completed as contemplated by the Merger Agreement, the ExpressJet stockholders will receive $6.75 in cash for each outstanding share of ExpressJet common stock, and the net acquisition price for all of the issued and outstanding shares of ExpressJet common stock (after giving effect to shares of ExpressJet common stock presently owned by Atlantic Southeast) would be approximately $133 million.  In connection with the proposed transaction, we have negotiated the terms of an amended capacity purchase agreement between ExpressJet and Continental Airlines, Inc., which we anticipate will become effective if the Merger is completed.  Completion of the Merger is subject to approval by ExpressJet’s stockholders, regulatory approvals and other customary closing conditions, and is currently expected to occur during the fourth quarter of 2010.

On October 16, 2009, SkyWest Airlines extended to United a secured term loan in the amount of $80 million. The term loan bore interest at a rate of 11%, with a ten-year amortization period. The loan was secured by certain ground equipment and airport slot rights held by United. On August 11, 2010, United repaid the $80 million term loan.

On September 29, 2010, we invested $7 million for a 30% ownership interest in Mekong Aviation Joint Stock Company, an airline operating in Vietnam (“Air Mekong”).  We anticipate accounting for the investment using the equity method of accounting and intend to reflect our equity interest in Air Mekong’s earnings on a one-quarter lag.

Critical Accounting Policies

Our significant accounting policies are summarized in Note 1 to our consolidated financial statements for the year ended December 31, 2009, which are presented in our Annual Report on Form 10-K for the year ended December 31, 2009.  Critical accounting policies are those policies that are most important to the preparation of our consolidated financial statements and require management’s subjective and complex judgments due to the need to make estimates about the effect of matters that are inherently uncertain. Our critical accounting policies relate to revenue recognition, maintenance, aircraft leases, impairment of long-lived assets and intangibles, share-based compensation expense and fair value. The application of these accounting policies involves the exercise of judgment and the use of assumptions as to future uncertainties and, as a result, actual results will differ, and could differ materially, from such estimates.

Results of Operations

Three Months Ended September 30, 2010 and 2009

Operational Statistics.  The following table sets forth our major operational statistics and the associated percentages-of-change for the periods identified below.

Revenues.  Operating revenues increased $49.1 million, or 7.7%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. We are reimbursed for our actual fuel costs by our major partners under our contract flying arrangements. For financial reporting purposes, we record these reimbursements as operating revenue. Under the SkyWest Airlines and Atlantic Southeast Delta Connection Agreements, we are reimbursed for our engine overhaul expenses as incurred. We also record those engine overhaul reimbursements as operating revenue. The following table summarizes the amount of fuel and engine overhaul reimbursements included in our passenger revenues for the periods indicated (dollar amounts in thousands).

Passenger revenues.  Passenger revenues increased $47.0 million, or 7.5%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in passenger revenues was due to an increase in fuel reimbursements from our major partners. The fuel reimbursement from our major partners increased $14.6 million or 28.2%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. Our passenger revenues, excluding fuel and engine overhaul reimbursements from major partners, increased $36.6 million, or 6.7%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in passenger revenues, excluding fuel and engine overhaul reimbursements, was generally consistent with the increase in ASMs. The increase in ASMs was primarily due to SkyWest Airlines acceptance of 18 new CRJ 700s since April 1, 2009 and its incremental placement of those aircraft into service over that period.

Ground handling and other.  Total ground handling and other revenues increased $2.1 million, or 27.4%, during the three months ended September 30, 2010, compared to the three  months ended September 30, 2009. The increase is primarily related to aircraft rental revenue to other airlines.  During the three months ended September 30, 2010, we  obtained leases for four CRJ900s and subleased the aircraft to Air Mekong.

Individual expense components are also expressed in the following table on the basis of cents per ASM. ASM is a common metric used in the airline industry to measure an airline’s passenger capacity. ASMs reflect both the number of aircraft in an airline’s fleet and the seat capacity for the aircraft in the fleet. As the size of our fleet is the underlying driver of our operating costs, the primary basis for our presentation of the following information on a cost per ASM basis is to discuss significant changes in our costs not proportionate to the relative changes in our fleet size (dollar amounts in thousands).

Fuel.  Fuel costs increased $25.4 million, or 41.1%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The average cost per gallon of fuel increased to $2.55 per gallon during the three months ended September 30, 2010, from $2.23 per gallon during the three months ended September 30, 2009. Commencing on June 1, 2009, Delta purchased the majority of the fuel for our Delta Connection aircraft.  United also purchased fuel directly from a fuel vendor for our United Express aircraft under contract flying operated out of Chicago, San Francisco, Los Angeles and Denver. The following table summarizes the gallons of fuel we purchased directly, and the change in fuel price per gallon on our fuel expense, for the periods indicated:

Salaries Wages and Employee Benefits.  Salaries, wages and employee benefits increased $9.8 million, or 5.6%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The average number of full-time equivalent employees increased 3.9% to 12,704 for the three months ended September 30, 2010, from 12,227 for the three months ended September 30, 2009.  The increase in the number of employees, and corresponding increase in crew-related salaries, wages and employee benefits, was primarily due to the increase in block hours and ASMs.

Aircraft maintenance, materials and repairs.  Maintenance costs increased $1.8 million, or 1.5%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The following table summarizes the amount of engine overhauls and engine overhaul reimbursements included in our aircraft maintenance expense for the periods indicated (dollar amounts in thousands).

Aircraft maintenance expense excluding reimbursed engine overhauls and CRJ 200 engine overhauls reimbursed at fixed hourly rates, increased $3.9 million, or 5.5%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in maintenance expense excluding engine overhaul costs, was principally due to the increase in block hours.

Under the SkyWest Airlines and Atlantic Southeast United Express Agreements, we recognize revenue in our condensed consolidated statement of income at a fixed hourly rate for mature engine maintenance on regional jet engines and we recognize engine maintenance expense on our CRJ200 regional jet engines in our condensed consolidated statement of income on an as-incurred basis as maintenance expense. During the three months ended September 30, 2010, our CRJ200 engine expense under our SkyWest Airlines and Atlantic Southeast United Express Agreements and our AirTran code-share agreement increased $2.1 million compared to the three months ended September 30, 2009.  The increase in CRJ 200 engine overhauls reimbursed at a fixed hourly rate was principally due to scheduled engine maintenance events.  We anticipate the average quarterly number of scheduled engine

19

Table of Contents

maintenance events we experienced during the three months ended September 30, 2010 will likely continue each quarter through 2010 and 2011 and the first quarter of 2012.

Under our Delta Connection Agreements we are reimbursed for engine overhaul costs by Delta at the time the maintenance event occurs. Such reimbursements are reflected as passenger revenue in our condensed consolidated statements of income.

Aircraft rentals.  Aircraft rentals increased $1.4 million, or 1.8%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009.  During the three months ended September 30, 2010, we obtained leases for four CRJ900s and subleased the aircraft to Air Mekong.

Depreciation and amortization.  Depreciation and amortization expense increased $3.3 million, or 6.0%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009.  The increase in depreciation expense was primarily due to SkyWest Airlines taking delivery of 18 new CRJ700s since April 1, 2009. These aircraft were financed through long-term debt.

Station rentals and landing fees.  Station rentals and landing fees expense increased $4.3 million, or 15.5%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in station rentals and landing fees expense was primarily due to an increase in the number of departures during the three months ended September 30, 2010 compared to the corresponding period of 2009.

Ground handling service.  Ground handling service expense increased $3.2 million, or 13.5%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in ground handling expense was due primarily to the expense SkyWest Airlines incurred in connection with outsourcing ten  new pro-rate stations to other ground handlers since October 1, 2009.

Other expenses.  Other expenses, primarily consisting of property taxes, hull and liability insurance, crew simulator training and crew hotel costs, increased $4.9 million, or 13.7%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in other expenses was primarily due to the increase in ASMs during the three months ended September 30, 2010.

Interest.  Interest expense increased $0.5 million, or 2.3%, during the three months ended September 30, 2010 compared to the three months ended September 30, 2009. The increase in interest expense was primarily due to SkyWest Airlines taking incremental delivery of 18 new CRJ700s since April 1, 2009. These aircraft were financed through long-term debt.

Interest Income. Interest income increased $1.0 million, or 52.6% during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. The increase in interest income was due primarily to the secured term loan SkyWest Airlines extended to United during the fourth quarter of 2009 in the amount of $80 million. The term loan bore interest at a rate of 11%, with a ten-year amortization period. SkyWest Airlines also agreed to defer $49 million otherwise payable by United to SkyWest Airlines under the SkyWest Airlines United Express Agreement.  This amount accrued a deferral fee of 8% which was included in interest income.  On August 11, 2010, United repaid the $80 million term loan.

Total Airline Expenses.  Total airline expenses (consisting of total operating and interest expenses) increased $54.6 million, or 9.2%, during the three months ended September 30, 2010, compared to the three months ended September 30, 2009. We are reimbursed for our actual fuel costs by our major partners under our contract flying arrangements. We record the amount of those reimbursements as revenue. Under the SkyWest Airlines and Atlantic Southeast Delta Connection Agreements, we are reimbursed for our engine overhaul expense, which we record as revenue. The following table summarizes the amount of fuel and engine overhaul expenses which are included in our total airline expenses for the periods indicated (dollar amounts in thousands).
