U.S. forces Delta and Aeromexico to end their partnership over fairness issues

The U.S. Department of Transportation took decisive action against Delta Air Lines and Aeromexico by ordering the dissolution of their joint venture, which facilitated flights between the U.S. and Mexico. This decision, effectively announced on September 16, 2025, was based on concerns regarding anti-competitive effects in the U.S.-Mexico aviation markets. Transportation Secretary Sean Duffy emphasized that the airline partnership led to unfair advantages for both Delta and Aeromexico, ultimately harming consumers and stakeholders. The joint venture, which received antitrust immunity in 2016, allowed the airlines to collaborate on pricing, scheduling, and revenue-sharing, effectively limiting competition. The Transportation Department had previously indicated potential action in July, highlighting issues around fairness in the markets. Duffy expressed concerns over Mexico's treatment of U.S. carriers, particularly regarding the relocation of airlines from the Benito Juarez International Airport to the Felipe Angeles International Airport, 30 miles away. This shift was viewed as violating prior trade agreements, providing domestic airlines an edge while disadvantaging U.S. airlines. Mexican President Claudia Sheinbaum defended the decision as a technical measure to reduce congestion at Benito Juarez Airport rather than an action against U.S. airlines, but U.S. officials remain skeptical. As the announcement took effect, both Delta and Aeromexico expressed disappointment, arguing that the termination of their partnership could lead to significant ethical and economic ramifications, including job losses and reduced connectivity. Both airlines committed to maintaining operational flights even without their joint venture. The outcome of the order underscores ongoing trade tensions and regulatory scrutiny concerning air travel and competitiveness in the region.
