White House Blames Biden for Aviation Deal Collapse with Mexico

Regulatory Measures Against Mexican Airlines

The U.S. Department of Transportation (DOT) has implemented a series of regulatory measures targeting Mexican airlines, citing alleged violations of the 2015 Air Transport Agreement. These actions, announced on July 19, 2025, by U.S. Secretary of Transportation Sean Duffy, are part of a broader initiative under the 'America First' strategy. The DOT claims that Mexico has failed to adhere to the agreement, which was designed to ensure fair competition and market access between the two nations.

Alleged Non-Compliance with the 2015 Agreement

Since 2022, Mexico has been accused of engaging in anticompetitive behavior, including the sudden cancellation of slots at Mexico City's Benito Juárez International Airport. This decision disrupted operations for both American and Mexican airlines, leading to increased costs and operational challenges. Additionally, a 2023 decree required cargo operations to be relocated, further straining the aviation relationship between the U.S. and Mexico.

Specific Violations Attributed to Mexico

Among the most notable violations is the cancellation of slots at Benito Juárez International Airport. This move affected major U.S. airlines such as American, Delta, and United, as well as Mexican carriers like AeroMexico, Viva Aerobus, and Volaris. The relocation of cargo operations to Felipe Ángeles International Airport was justified by Mexico due to capacity limitations, a claim the U.S. disputes. Furthermore, the absence of a non-discriminatory slot allocation system contradicts the terms of the 2015 agreement.

Impact of Mexico's Actions

The DOT asserts that these actions have disrupted commercial flows and increased operational costs for U.S. companies. The financial burden on American businesses has been significant, with millions in additional costs incurred. The DOT warns that these actions harm airlines seeking market entry, existing competitors, and consumers who rely on timely air cargo shipments. The regulatory measures aim to restore balance and protect U.S. interests in the aviation sector.

New Measures Imposed by the U.S.

In response, the U.S. has introduced several new measures. Mexican airlines are now required to submit detailed schedules of their U.S. operations to the DOT. Any large passenger or cargo charter flights from Mexican airlines must now receive prior approval from the DOT. Additionally, the U.S. proposes withdrawing antitrust immunity from the Delta-AeroMexico joint venture, arguing that Mexico's market interventions have created an unfair competitive environment.

Blame on the Previous Administration

Secretary Duffy directly criticized the previous administration, stating that former President Joe Biden and former Secretary of Transportation Pete Buttigieg allowed Mexico to breach the bilateral aviation agreement. Duffy emphasized that these actions signal the end of such leniency, warning other countries against exploiting U.S. airlines and markets. The 'America First' strategy underscores the commitment to fair competition and market integrity.

Potential Consequences for the Delta-AeroMexico Partnership

If the antitrust immunity withdrawal is finalized, the Delta-AeroMexico partnership would lose its ability to coordinate pricing and revenue sharing. However, Delta could maintain its stake in AeroMexico. Delta warns that this proposal could harm consumers traveling between the U.S. and Mexico, jeopardizing routes and economic benefits. AeroMexico is reviewing the order and plans to respond jointly with Delta. The aviation industry faces potential disruptions as these measures take effect.

Ongoing Diplomatic Talks

As of July 2025, diplomatic talks between the U.S. and Mexico continue, aiming to restore normal aviation services and uphold bilateral commitments. Mexican President Claudia Sheinbaum has not yet commented on the restrictions, leaving the future of U.S.-Mexico aviation relations uncertain. The ongoing negotiations highlight the complexities of international aviation agreements and the need for cooperative solutions.
