Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of American Airlines Group Inc. (we, us, our and similar terms, or AAG) should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2024. The accompanying unaudited condensed consolidated financial statements include the accounts of AAG and its wholly-owned subsidiaries. AAG’s principal subsidiary is American Airlines, Inc. (American). All significant intercompany transactions have been eliminated.

Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits.

Effective January 1, 2025, we adjusted the estimated useful lives of our mainline and regional aircraft, engines and related rotable parts by three years to align with the extended lives of aircraft included in our long-term fleet plan. In conjunction with this change, we also reduced the salvage values for most of these assets from 10% to 5% of original cost to more closely reflect the estimated value at the end of the useful life. Accordingly, the estimated useful lives for the principal property and equipment classification are as follows:

Principal Property and Equipment Classification	Estimated Useful Life
Aircraft, engines and related rotable parts	20 – 33 years
