On July 19, 2025, U.S. Transportation Secretary Sean P. Duffy announced enforcement actions against Mexico for violating the 2015 Air Transport Agreement, claiming Mexico’s actions have disrupted U.S. passenger and cargo operations since 2022. Key measures include requiring Mexican airlines to file schedules with the U.S. Department of Transportation, mandating prior approval for large charters, and proposing to revoke antitrust immunity for the Delta-Aeromexico partnership. Duffy asserted that the U.S. will not tolerate violations and is monitoring other countries for similar breaches.
