OTHER | OTHER Terminated Acquisition In November 2021, the Company entered into an agreement to acquire global flight booking provider Etraveli Group. The completion of the acquisition was subject to certain closing conditions, including regulatory approvals. In September 2023, the European Commission announced its decision to prohibit the acquisition and consequently a termination fee of 85 million Euros ($90 million) was paid by the Company in October 2023 and is recorded in "General and administrative" expenses in the Consolidated Statement of Operations for the year ended December 31, 2023. Benefit Plans The Company maintains a defined contribution 401(k) savings plan covering certain U.S. employees and participates in certain defined contribution plans outside of the U.S. for which it provides contributions for eligible employees. The Company's contributions to the defined contribution plans during the years ended December 31, 2024, 2023, and 2022 were $59 million, $55 million, and $40 million, respectively.
