Income Taxes	Income Taxes At December 31, 2023, we had approximately $13.7 billion of gross federal net operating losses (NOLs) and $4.7 billion of other carryforwards available to reduce future federal taxable income, of which $3.4 billion will expire beginning in 2029 if unused and $15.0 billion can be carried forward indefinitely. We also had approximately $5.5 billion of NOL carryforwards to reduce future state taxable income at December 31, 2023, which will expire in taxable years 2023 through 2043 if unused. Our ability to use our NOLs and other carryforwards depends on the amount of taxable income generated in future periods. We provide a valuation allowance for our deferred tax assets, which include our NOLs, when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We have determined that positive factors outweigh negative factors in the determination of the realizability of our deferred tax assets. There can be no assurance that an additional valuation allowance on our net deferred tax assets will not be required. Such valuation allowance could be material.

Many factors are considered that impact American’s assessment of future profitability, including conditions which are beyond its control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. American has determined that positive factors outweigh negative factors in the determination of the realizability of its deferred tax assets. There can be no assurance that an additional valuation allowance on American’s net deferred tax assets will not be required. Such valuation allowance could be material.

The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. Our short-term investments, restricted cash and restricted short-term investments classified as Level 2 utilize significant observable inputs, other than quoted prices in active markets, for valuation of these securities. No changes in valuation techniques or inputs occurred during the three months ended March 31, 2024. Assets measured at fair value on a recurring basis are summarized below (in millions): Fair Value Measurements as of March 31, 2024 Total Level 1 Level 2 Level 3 Short-term investments (1), (2) : Money market funds $ 350 $ 350 $ — $ — Corporate obligations 5,010 — 5,010 — Bank notes/certificates of deposit/time deposits 1,886 — 1,886 — Repurchase agreements 450 — 450 — 7,696 350 7,346 — Restricted cash and short-term investments (1), (3) 895 436 459 — Long-term investments (4) 117 117 — — Total $ 8,708 $ 903 $ 7,805 $ — (1) All short-term investments are classified as available-for-sale and stated at fair value.

On September 21, 2021, the United States Department of Justice, joined by Attorneys General from six states and the District of Columbia, filed an antitrust complaint against American and JetBlue Airways Corporation (JetBlue) in the U.S. District Court for the District of Massachusetts alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed Northeast Alliance arrangement (NEA). On May 19, 2023, the U.S. District Court for the District of Massachusetts issued an order permanently enjoining American and JetBlue from continuing and further implementing the NEA. In June 2023, JetBlue delivered a notice of termination of the NEA, effective July 29, 2023, and the carriers have commenced wind-down activities to accommodate mutual customers. Following written submissions by the parties and a hearing on July 26, 2023, the U.S. District Court for the District of Massachusetts entered a Final Judgment and Order Entering Permanent Injunction on July 28, 2023. The parties are complying with the terms of the Final Judgment and Order Entering Permanent Injunction, including winding down activities related to the NEA. American filed a notice of appeal to the U.S. Court of Appeals for the First Circuit on September 25, 2023, and such appeal remains pending. Private Party Antitrust Actions Related to the Northeast Alliance. On December 5, 2022 and December 7, 2022, two private party plaintiffs filed putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the Eastern District of New York alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed NEA. These actions were consolidated on January 10, 2023. The private party plaintiffs filed an amended consolidated complaint on February 3, 2023. On February 2, 2023 and February 15, 2023, private party plaintiffs filed two additional putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the District of Massachusetts and the U.S. District Court for the Eastern District of New York, respectively. In March 2023, American filed a motion in the U.S. District Court for the District of Massachusetts case asking to transfer the case to the U.S. District Court for the Eastern District of New York and consolidate it with the cases pending in that venue. The U.S. District Court for the District of Massachusetts granted that motion. The remaining cases were consolidated with the other actions in the Eastern District of New York. In June 2023, the private party plaintiffs filed a second amended consolidated complaint, followed by a third amended complaint filed in August 2023. In September 2023, American, together with JetBlue, filed a motion to dismiss the third amended complaint, and that motion remains pending.
