The order to end the partnership will not take effect until October, allowing airlines time to contest the decision.

If antitrust approval for Delta and Aeromexico is rescinded, they would need to cease cooperation on pricing and capacity, though Delta would retain its stake and market presence in the U.S.-Mexico corridor.

In response, the U.S. Department of Transportation has mandated that all Mexican airlines submit their flight schedules for approval until Mexico improves its treatment of U.S. carriers.

Additionally, Mexican airlines must seek U.S. approval for large charter flights, aiming to ensure fair competition.

The U.S. Department of Transportation is also considering withdrawing antitrust immunity from Delta's joint venture with Aeromexico to address competitive concerns.

U.S. officials, including Transportation Secretary Sean Duffy, have indicated that flight requests from Mexico could be disapproved if issues like slot rescindments and cargo relocations are not resolved.

Mexico's government, led by President Claudia Sheinbaum, has not publicly responded to these new restrictions.

The broader impact of these airline and regulatory disputes on U.S.-Mexico trade relations and tariff negotiations remains uncertain.

The Trump administration has imposed new restrictions on flights from Mexico and announced plans to terminate Delta Air Lines' partnership with Aeromexico, citing Mexico's limitations on flights to Mexico City.

The U.S. government argues that Mexico's actions have disrupted the market, creating unfair advantages and harming U.S. airlines and consumers dependent on air travel and cargo shipments.

Despite promises of infrastructure upgrades at Mexico City's Benito Juarez International Airport to reduce congestion, no progress has been reported after three years.
