The Business Travel News 2025 Corporate Travel 100 is BTN’s effort to identify the 100 companies with the most business travel spend in the United States based on full-year 2024 U.S.-booked air volume.

BTN’s executive director of conference content and strategy David Meyer contacted previous and new targets for the 2025 Corporate Travel 100 conducted online surveys and phone interviews to gather the data. The full results of the survey are provided to those companies who participate in the interview process.

Certain companies decline the BTN outreach. For companies on the list that chose not to confirm U.S.-booked business air travel volumes, BTN used industry sources, published reports and other intelligence about specific programs to provide an estimate of U.S.-booked air volume. Estimates are noted in the listings.
