Legal Proceedings	Legal Proceedings Private Party Antitrust Actions Related to the Northeast Alliance (NEA). On December 5, 2022 and December 7, 2022, two private party plaintiffs filed putative class action antitrust complaints against AAG and JetBlue Airways Corporation (JetBlue) in the U.S. District Court for the Eastern District of New York alleging that AAG 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 AAG 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, AAG 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, AAG, together with JetBlue, filed a motion to dismiss the third amended complaint. In September 2024, the court denied that motion. AAG and JetBlue filed answers to the private party plaintiffs’ third amended complaint in October 2024. In July 2026, the remaining private party plaintiff filed a motion for class certification limited to purchasers of American and JetBlue flights to or from Boston from April 1, 2021 through July 28, 2023. In October 2026, AAG, together with JetBlue, filed an opposition to that motion. We believe these lawsuits are without merit and are defending against them vigorously. General. In addition to the specifically identified legal proceedings, we and our subsidiaries are also engaged in other legal proceedings from time to time. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Therefore, although we will vigorously defend ourselves in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain but could be material.
