Delta’s Lawsuit Against The U.S. Government Over Its Mexico Flight Partnership Takes A Turn After Surprise Court Ruling

For nearly a decade, Delta Air Lines and Aeroméxico have operated as partners, coordinating flights, schedules, and fares across some of the busiest U.S.–Mexico routes. But in September, the U.S. Department of Transportation (DOT) moved to break up that relationship, arguing that the joint venture was creating "anticompetitive effects" in key Mexico City markets. The agency gave both airlines a deadline of January 1, 2026, to dismantle the partnership.

Delta and Aeroméxico pushed back by filing a lawsuit with the Eleventh Circuit Court of Appeals in early October. Now, a new ruling from the court has unexpectedly shifted the case.
