Court Throws Out DOT Order Targeting Delta-Aeromexico JV

The DOT Tried to Split Delta and Aeromexico. An Appeals Court Said No.

The Department of Transportation wanted to rip apart Delta Air Lines and Aeromexico. An appeals court just told them they can't. In a ruling handed down this week, the 11th Circuit Court of Appeals threw out the DOT’s order to dismantle the cross-border joint venture, preserving one of North America's most critical airline partnerships. For the millions of travelers flying between the U.S. and Mexico, it's business as usual.

Regulators in Washington spent months arguing that the decade-old pact had to end. But the appellate judges looked at the government’s reasoning and sided firmly with the airlines instead. By killing the DOT’s termination order, the court locked the legal foundation back in place—the same setup that's kept the two carriers operating as one since the mid-2010s.

What It Means if You're Flying South

If you routinely book flights to Mexico, you can breathe easy. The ruling protects the coordinated flight schedules, seamless connections, and shared frequent-flyer benefits passengers rely on. Killing an international joint venture isn’t just dropping a few codeshare routes. It means blowing up combined pricing, gutting capacity planning, and rewiring flight schedules from scratch. Thanks to the 11th Circuit, travelers won't have to deal with a splintered network.

Delta jumped at the chance to praise the outcome. In a statement issued right after the ruling dropped, the airline pointed back to what the pair has built over the past decade, arguing the partnership has expanded traveler options, boosted regional economies, and backed American jobs. Just as important for both carriers, the win dodges an expensive, chaotic redrawing of their entire North American map.

A Clear Check on Washington's Regulatory Push

For the past few years, federal regulators have taken a hammer to airline partnerships, targeting antitrust-immunized alliances across the board. This decision puts down a hard marker. Agencies can't simply wake up and shred long-approved international agreements without proving their case under serious judicial scrutiny. It’s a major brake on how far Washington can reach to unwind historic approvals after the fact.

With the legal cloud lifted, Delta and Aeromexico can shift their attention back to running their networks. Both carriers say their immediate priorities remain passenger service, workforce stability, and local community investments across their joint footprint. Flyers keep their direct routes and straightforward connections. And for the DOT, it's a blunt lesson: aggressive regulatory crackdowns still have to survive the courtroom.
