BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of Alaska Air Group, Inc. (Air Group or the Company) include the accounts of the parent company, Alaska Air Group, Inc., and its principal subsidiaries, Alaska Airlines, Inc. (Alaska) and Horizon Air Industries, Inc. (Horizon), through which the Company conducts substantially all of its operations. These interim condensed consolidated financial statements are unaudited and should be read in conjunction with the consolidated financial statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2010. In the opinion of management, all adjustments have been made that are necessary to present fairly the Company’s financial position as of September 30, 2011, as well as the results of operations for the three and nine months ended September 30, 2011 and 2010. The adjustments made were of a normal recurring nature. 

The Company’s interim condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP). In preparing these statements, the Company is required to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities, as well as the reported amounts of revenues and expenses. Significant estimates made include assumptions used to record expenses and revenues associated with the Company’s Mileage Plan; assumptions used in the calculations of pension expense in the Company’s defined-benefit plans; and the amounts of certain accrued liabilities. Actual results may differ from the Company’s estimates.

Certain reclassifications have been made to conform the prior year’s data to the current format.

New and Prospective Accounting Pronouncements

The Financial Accounting Standards Board (FASB) has issued a number of Accounting Standards Updates (ASUs). Those ASUs are as follows:

• In September 2009, the FASB issued ASU 2009-13, Multiple Deliverable Revenue Arrangements - A Consensus of the FASB Emerging Issues Task Force. This update provides application guidance on whether multiple deliverables exist, how the deliverables should be separated and how the consideration should be allocated to one or more units of accounting. This guidance also eliminates the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. This accounting standard was effective for the Company for revenue arrangements entered into or materially modified in fiscal years beginning on January 1, 2011. It primarily impacts the accounting for recognition of revenue associated with frequent flyer credits. There was no immediate significant impact of this new standard on the Company's consolidated financial statements and there will be no impact until the Company materially modifies or enters into new contracts associated with its frequent flyer program.

• In May 2011, the FASB issued ASU 2011-04, Fair Value Measurement - Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs. The standard revises guidance for fair value measurement and expands the disclosure requirements. It is effective for fiscal years beginning after December 15, 2011. The Company is currently evaluating the impact that the adoption of this standard will have on the Company's consolidated financial statements.

• In June 2011, the FASB issued ASU 2011-05, Comprehensive Income - Presentation of Comprehensive Income. The standard revises guidance for the presentation and prominence of the items reported in other comprehensive income. It is effective for fiscal years beginning after December 15, 2011. The Company is currently evaluating the impact that the adoption of this standard will have on the presentation of the Company's consolidated financial statements.

The FASB has issued a number of proposed ASUs. Those proposed ASUs are as follows:

• Proposed ASU - Revenue Recognition - was issued in June 2010 and continues to evolve. We believe that a new revenue recognition standard could significantly impact the Company's accounting for the Company's Mileage Plan frequent flyer credits earned by passengers who fly on us or our partners, or miles sold to third parties.

• Proposed ASU - Leases - was issued in August 2010 and continues to evolve. This proposed standard overhauls accounting for leases and would apply a “right-of-use” model in accounting for nearly all leases. For lessees, this would result in recognizing an asset representing the lessee's right to use the leased asset for the lease term and a liability to make lease payments. This proposed standard eliminates the operating lease concept from an accounting perspective, thereby eliminating rent expense from the income statement. This proposed standard, if adopted, would significantly impact the Company's consolidated financial statements.

These proposed ASUs are subject to change and no effective dates have been assigned.
