The Trump administration has escalated tensions with Mexico by threatening to reject flight requests from Mexican airlines and revoke antitrust immunity for the joint pricing agreement between Delta Air Lines and Grupo Aeroméxico. The U.S. Department of Transportation alleges that Mexico has violated the 2015 bilateral Air Transport Agreement by forcing cargo airlines to relocate their operations from Mexico City's Benito Juárez International Airport (AICM) to the Felipe Ángeles International Airport (AIFA), and by abruptly cutting flight slots for U.S. carriers. These actions are cited as anti-competitive behavior that has negatively impacted U.S. airlines. In response, the Mexican government defends the relocation of cargo flights to AIFA, arguing that it has improved operational efficiency and aviation safety in the Mexico City metropolitan area. Aeroméxico and Delta have stated they are reviewing the U.S. Department of Transportation's orders and plan to respond jointly. The U.S. measures include potential rejection of Mexican flight applications, removal of antitrust protections for the Delta-Aeroméxico alliance, and increased scrutiny of flight schedules and charter services. Mexico maintains its commitment to competitive aviation despite the U.S. restrictions, which represent a significant escalation in the ongoing bilateral aviation dispute stemming from decisions made during the administration of President Andrés Manuel López Obrador.
