Is Aeromexico owned by Delta Air Lines?

Is aeromexico owned by delta air lines? Alliance guide

Delta Air Lines does not own Aeromexico outright. Aeromexico operates as an independent Mexican carrier, though Delta holds a 20% minority stake and shares a comprehensive joint venture alliance covering transborder travel.

Is Aeromexico Fully Owned by Delta Air Lines?

This question frequently causes confusion because the two airlines operate so seamlessly together on transborder flights. However, Aeromexico remains an independent Mexican company. Delta Air Lines currently holds just a 20% minority equity stake in Grupo Aeroméxico, rather than full ownership.

Let us be honest - the delta and aeromexico relationship is incredibly complex. I used to assume they were essentially the same company after flying a route where my ticket said Delta but the plane was entirely Aeromexico. Most travelers assume booking a codeshare flight is identical no matter which website you use. But there is one counterintuitive factor about these partner bookings that costs flyers thousands of miles annually - I will explain it in the SkyMiles section below.

The financial reality of the airlines themselves is equally complicated. Before the global pandemic, Delta held a significant 49% stake in the Mexican carrier. When Aeromexico entered Chapter 11 bankruptcy restructuring in 2020, the entire ownership structure shifted. The shares belonging to Delta were heavily diluted down to 20%, while Apollo Global Management emerged as the largest shareholder with a 22.4% stake. Several other Mexican investors hold the remaining shares.

Does this matter for your upcoming vacation? Usually not. The operational integration remains completely intact.

Understanding the Delta-Aeromexico Joint Venture (2026 Update)

While Delta does not own Aeromexico outright, the two carriers operate under a Joint Cooperation Agreement granting them antitrust immunity. They coordinate pricing, schedules, and capacity as a single entity on routes between the United States and Mexico.

Rarely have I seen an airline alliance face as much recent legal drama as this one. The U.S. Department of Transportation originally ordered the dissolution of this joint venture by January 2026. The agency cited anticompetitive actions by the Mexican government, specifically the decision capping hourly operations at Mexico City International Airport from 52 down to 43 flights. Furthermore, the joint venture controlled 73% of the cargo market between the two countries, creating a significant competitive advantage.

But there is a catch.

In August 2026, a U.S. Court of Appeals overturned the DOT order, ruling it arbitrary. This massive legal victory means the alliance survives. Your transborder flights are safe for now.

Can I Use Delta SkyMiles on Aeromexico?

Yes, absolutely. Because both airlines are founding members of the SkyTeam Alliance, their frequent flyer programs are heavily intertwined.

Here is that counterintuitive factor regarding miles I mentioned earlier: the earning rates vary wildly depending on whose flight number is on your receipt. When I first tried optimizing my Medallion Qualification Dollars, I completely misunderstood how codeshares work. I booked a flight operated by Delta through the Aeromexico website. The result? I earned significantly fewer elite qualifying metrics than if I had booked the exact same seat through Delta.

You earn qualification metrics on Aeromexico marketed flights based on a percentage of the distance flown rather than the ticket price. For deeply discounted premium cabin fares, this distance calculation can actually be more lucrative than the standard revenue model. You just need to know which system benefits your specific itinerary.

Navigating Alliance Benefits: Lounge Access and Upgrades

Because both carriers participate in the SkyTeam Alliance, elite status benefits generally transfer across borders. Your Medallion status provides tangible perks when flying south.

If you hold Gold, Platinum, or Diamond Medallion status, you receive SkyTeam Elite Plus recognition. This grants you access to the Aeromexico Salon Premier lounges in Mexico City and other hubs, regardless of your class of service. I used to assume my Silver Medallion status would get me into the lounge. I learned the hard way that Silver only maps to regular SkyTeam Elite, which does not include lounge access.

Upgrades are another area where the partnership shines. Elite members are eligible for complimentary upgrades to Aeromexico Clase Premier on most transborder flights. However, these upgrades clear differently than domestic Delta flights. They are processed at the gate rather than days in advance, requiring a bit more patience at the boarding area.

Choosing How to Book Your Transborder Flight

Booking via Delta Air Lines

• Seamless earning of SkyMiles and Medallion Qualification Dollars based on ticket price

• Full control over seat selection and real-time tracking in the Delta app

• Handled by US-based agents at Delta, which is often faster for US travelers

Booking via Aeromexico

• Earns Medallion Qualification Dollars based on distance flown rather than fare paid

• Requires using the app belonging to Aeromexico for full reservation control

• Handled directly by Aeromexico, which can introduce friction during weather disruptions

The Codeshare Confusion Journey

David, a frequent business traveler based in Atlanta, needed to fly to Monterrey, Mexico. He booked an Aeromexico flight directly through their website, assuming his Delta Diamond status would seamlessly apply to the reservation.

When he arrived at the airport, the friction began. His priority security screening did not carry over to the Aeromexico boarding pass, and the Delta app would not let him select a premium seat. He spent 45 minutes at the check-in desk trying to link his SkyMiles number manually.

The realization came when a supervisor explained the nuances of the joint venture systems. He learned that to get all his Delta benefits automatically, he needed to book the Aeromexico operated flight with a DL flight number through the Delta platform.

For his return trip, he booked the proper codeshare flight. The app recognized his status immediately, granted him an automatic upgrade to the Aeromexico AM Plus seating, and credited his account within 24 hours of landing.
