The Trump administration announced new restrictions on Mexican airlines and threatened to impact the alliance between Aeromexico and Delta, due to what it sees as Mexico's failure to comply with bilateral agreements.

The series of measures "to combat Mexico's flagrant non-compliance with the 2015 United States-Mexico Air Transport Agreement and its continued anti-competitive conduct" were announced by U.S. Transportation Secretary Sean Duffy.

The official blamed the Biden administration (2021-2025) for allowing “deliberately” that Mexico broke the bilateral aviation pact. "That ends today," the secretary warned.

From now on, Mexican airlines must submit their flight schedules to the Department of Transportation (DOT), according to a statement published on the DOT website.

The entity also announced that "any charter flight of large Mexican passenger or cargo aircraft" traveling to or from the U.S. must have its prior authorization.

Duffy also proposed revoking the antitrust immunity (ATI) under which the alliance between the American company Delta and the Aeroméxico company operates, one of the most important in the field of aviation between both countries.

These “corrective measures” are taken to “address competition issues in the marketplace,” the DOT text explains.

“Let these actions serve as a warning to any country that believes it can take advantage of the U.S., our airlines, and our market,” Duffy added on his official X account.

According to the U.S., Mexico stopped complying with the bilateral air pact since 2022 when it forced cargo airlines to relocate their operations from the main Benito Juárez Airport (MEX) to the new Felipe Ángeles airfield, almost 50 kilometers away,to ease congestion at the main port.

“By restricting slots and requiring cargo operations to move out of Mexico, Mexico has broken its promise, disrupted the market, and left U.S. companies holding the bag for millions in additional costs,” the DOT added.

The statement insists that Trump and Duffy “are taking note of many other countries that are violating the terms of our air transport agreements” and as an example warns that the U.S. is monitoring the actions of European countries to ensure that they “do not implement unjustified operating restrictions.”

Trump announced this last week in a letter to his Mexican counterpart, Claudia Sheinbaum, who will impose a 30% tariff on Mexican products starting August 1, taxes that could be modified "up or down," depending on relations between the two nations.

Shortly after, Mexico announced that they were already negotiating with their northern neighbors to protect businesses and jobs on both sides of the border, in response to the announcement of the imposition of new tariffs, which the Mexican government considers "unfair treatment."
