Delta Raises Concern Over Potential Loss of 20 US-Mexico Routes

Delta Air Lines has expressed concern over the potential loss of 20 routes launched in 2024 under its partnership with Aeroméxico, following the US Department of Transportation’s (DOT) review of their joint venture.

“We have this concern, and I think it is not just for Delta and Aeroméxico, but for all the communities and cities we serve, because more than 20 routes were opened last year between Mexico and the United States,” said Juan Inzunza, Delta’s Regional Sales Manager for Mexico and JCA.

Despite the uncertainty, Inzunza said the airline remains optimistic about a positive outcome. He added that the DOT’s review is being carefully analyzed in the context of the US-Mexico Bilateral Air Transport Agreement.

“We are awaiting the DOT’s response. Once we have clarity, we will make the necessary business decisions, always prioritizing connectivity and the benefits our customers expect,” Inzunza said.

The scrutiny comes after JetBlue sent a letter to the DOT arguing that alliances receive antitrust immunity (ATI) only when they guarantee the entry of new competitors into a market. The letter specifically referred to the Delta-Aeroméxico joint venture. JetBlue also criticized the alliance’s position that ATI should not be tied to access restrictions at key airports.

MBN reported that Aeroméxico and Delta Air Lines, partners since 2017 under a joint venture protected by US antitrust immunity, are awaiting a decision from the US Department of Transportation (DOT) on renewing the agreement, currently suspended. The outcome could influence their strategic alliance and connectivity between Mexico and the United States.

On July 19, 2025, the DOT issued an order tentatively revoking approval and antitrust immunity for the Delta–Aeroméxico partnership. If finalized, the immunity would end after a liquidation period on Oct. 25, 2025, potentially affecting routes and competition between the two countries.

Both airlines have submitted documentation to highlight the alliance’s importance. Giancarlo Mulinelli, Aeroméxico’s Senior Vice President of Global Sales, said an official update is expected “in the coming weeks.” 

As part of the alliance, Aeroméxico announced a new direct route from Mexico City to San Juan, Puerto Rico, beginning Oct. 29, 2025. Puerto Rico will be Aeroméxico’s 27th US destination, offering more than 1,300 weekly seats.
