The U.S. Department of Transportation announced Tuesday that it will terminate the approval of a joint collaboration between Delta Air Lines and Aeromexico, effective Jan. 1, 2026, according to a press release from the DOT.
The collaboration allowed for Delta Air Lines and Aeromexico to align their schedules, share revenues and jointly oversee routes between the US and Mexico since its establishment in 2017, according to Aerotime.
The DOT said Mexico has not been in compliance with the 2015 U.S.-Mexico Air Transport Agreement since 2022, which sought to promote and facilitate air travel between the countries while maintaining a competitive market.
“Empty promises mean nothing. After years of taking advantage of the U.S. and our carriers, we need to see definitive action by Mexico that levels the playing field and restores fairness,” said U.S. Transportation Secretary Sean P. Duffy in the release.
The DOT stated that “Mexico’s non-compliance intervenes in the market to provide an unfair advantage to Delta and Aeromexico, who operated a price and capacity-setting joint venture with conditional approval by USDOT.”
Delta and Aeromexico will be required to discontinue shared activities such as common pricing, capacity management and revenue sharing by next year, according to the release.
“We are disappointed that the Department of Transportation has chosen to terminate its approval of the strategic and pro-competitive partnership between Delta and Aeromexico, a decision that will cause significant harm to U.S. jobs, communities and consumers traveling between the U.S. and Mexico,” Delta Air Lines wrote in a statement on its website.
All Delta flights will continue to operate as normal unless stated otherwise, according to the statement.
