Overview
- The Transportation Department asked the 11th Circuit to deny Delta and Aeroméxico’s bid to pause its order ending their joint venture by Jan. 1, 2026.
- Regulators called the partnership “legalized collusion” and pointed to the carriers’ near‑60% share of Mexico City operations in arguing termination serves the public interest.
- Delta and Aeroméxico petitioned for review and say unwinding the pact on the current timetable would be operationally and financially burdensome, with Delta seeking a response by Nov. 14.
- The Justice Department backed the department’s competitive analysis in an August filing supporting the revocation.
- The move sits within broader U.S. actions on U.S.–Mexico air services, including freezing a Viva–Allegiant immunity bid, canceling new Mexico City routes, and proposing belly‑cargo limits.
