Mexico disagrees with the U.S. decision to revoke the alliance between Delta and Aeromexico.

MEXICO CITY.— This Monday, during her usual morning press conference, the president of Mexico , Claudia Sheinbaum Pardo , expressed her disagreement with the United States ' decision to revoke the antitrust immunity held by DeltaAir Lines and Aeroméxico , which allowed them to maintain a strategic alliance, and indicated that there could be other interests behind this measure.

Claudia Sheinbaum stated that Mexican authorities are reviewing the announcement made last week by the U.S. Department of Transportation . The U.S. government set January 1, 2026, as the deadline to end the antitrust partnership that allowed Delta Air Lines and Aeroméxico to set prices, routes, and capacity.

Washington used the announcement to once again object to Mexico's decision several years ago to move passenger and cargo flights from Mexico City's main airport to another airport on the outskirts of the capital. "We don't understand that position," the president said at her morning press conference, rejecting the measure and recalling that Mexico had responded to the four observations made by the Department of Transportation regarding the situation at Mexico City International Airport (AICM) and the relocation of some airlines to Felipe Ángeles Airport (AIFA).

"We believe there are other interests behind this resolution," said Claudia Sheinbaum, acknowledging that Mexico is reviewing whether any airline could benefit from the end of the alliance between Aeroméxico and Delta Air Lines .

Since July, Washington has imposed new restrictions on flights from Mexico to the United States in response to the Mexican government's requirement several years ago that passenger and cargo flights relocate to a different airport in the capital.

Mexico is the top foreign destination for Americans, with more than 40 million passengers flying to Mexico last year.

Since early last year, Delta and Aeroméxico have fought the Department of Transportation's efforts to end their partnership. The airlines have argued that it is unfair to punish them for the Mexican government's actions and said that canceling their agreement would jeopardize nearly two dozen routes and $800 million in benefits to both countries' economies from tourism spending and jobs.
