So, you're looking at Aeromexico flights to Mexico City. Honestly, it’s a weird time to be booking this route. If you haven't checked the news lately, there is a massive shake-up happening right now in January 2026.
The cozy relationship between Delta and Aeromexico basically just hit a brick wall. For years, you could book a flight on Delta's site, hop on an Aeromexico plane, and everything felt like one big happy family. Not anymore. The U.S. Department of Transportation (DOT) officially ordered the end of their "Joint Venture" as of January 1, 2026. This means they can't coordinate prices or schedules anymore. If you’re a frequent flyer, this is a bit of a headache.
What’s different now at MEX?
The airport situation in Mexico City is... well, it's a lot. You’ve got the classic Benito Juárez International (MEX) and the newer Felipe Ángeles International (NLU). Most Aeromexico flights to Mexico City still land at MEX, which is much closer to the city center—about 4 miles compared to NLU’s 24 miles.
But here is the kicker: the government has been slashing "slots" (takeoff and landing times) at the old MEX airport to force traffic over to NLU. This has made MEX feel a little more frantic than usual. If you’re flying from a major U.S. hub like Los Angeles (LAX), New York (JFK), or Miami (MIA), you’re likely still heading to MEX, but don't be shocked if your flight time gets nudged by 30 minutes every few weeks. It's just the reality of the slot wars right now.
The Delta breakup and your miles
If you’re a SkyMiles junkie, don’t panic, but do pay attention. While the "Joint Venture" is dead, Aeromexico is still a member of the SkyTeam alliance. You can still earn and use miles. However, the seamless "it’s basically the same airline" vibe is fading.
Booking directly through Aeromexico's website often yields better prices lately, but their tech is notoriously glitchy. I've had friends spend an hour trying to pay for a bag on the app only for it to crash three times. Sometimes, calling is faster. I know, it’s 2026 and we still have to use the phone. It's tragic.
Picking the right seat (The "Clase Premier" Confusion)
Aeromexico has rebranded its cabins more times than I can count. When looking at Aeromexico flights to Mexico City, you’ll see a few options that sound similar but are very different.
- Basic: The "don't bring a bag" fare. You get a personal item and a carry-on, but no checked bag.
- Classic: This is the standard. You get a discount on checked bags and can actually pick a seat without paying a king's ransom.
- AM Plus: Think of this as "Delta Comfort+" or "Economy Plus." More legroom, overhead bin priority, and SkyPriority check-in. On a 5-hour flight from Seattle (SEA), it’s worth the extra $50.
- Clase Premier: Their version of First Class. If you’re on a Boeing 787 Dreamliner (usually from JFK or LAX), you get lie-flat seats. If you’re on a 737, it’s just a bigger recliner.
One thing they do better than U.S. carriers? Even in economy, you usually get a snack and a drink. Yes, that includes tequila. They still believe in hospitality, even if their website doesn't.

Price trends: When to actually book
I checked the latest data for early 2026. April is currently the sweet spot for cheap Aeromexico flights to Mexico City. You can find round-trips from places like Dallas (DFW) or San Antonio (SAT) for under $250 if you're flexible.
Avoid December. Just don't do it. Prices triple, and the airport congestion at MEX becomes a literal nightmare. If you have to go during peak season, try to fly on a Tuesday or Wednesday. Saturday flights are consistently the most expensive for this route.
Real talk about the service
Let's be real: Aeromexico is currently sitting at a 4/10 on some review sites like Skytrax. Most of the complaints aren't about the flying; they're about the "ground experience."
If your flight is canceled, getting a refund can feel like a part-time job. They aren't as proactive as some U.S. airlines when things go wrong. However, once you are in the air? The crews are usually fantastic. They’re attentive, the food is actually edible, and the 787s are some of the quietest planes in the sky.
Navigating the airport like a pro
When you land at MEX Terminal 2 (Aeromexico’s home), the immigration lines can be a toss-up.
- Use the E-Gates: If you have a modern passport, look for the automated kiosks. They are way faster than the manual lines.
- The Salon Premier Lounges: If you have a Platinum Amex or a Clase Premier ticket, use the lounge. The one in Terminal 2 is decent, though the food is mostly just snacks and small sandwiches. It beats sitting at the gate, which is always overcrowded.
- Taxis vs. Uber: Uber works, but you have to walk a bit to a specific pickup point. If you’re tired, just buy a pre-paid taxi ticket at the kiosks inside the terminal. It’s safer and easier for your first time.
Your move
If you’re ready to lock in a trip, start by checking Google Flights to see the price history. Don't just look at the current price; see if it's "low" or "typical" for your dates. If you're flying from a Delta hub, compare the price on both sites. Sometimes Delta is cheaper for the exact same Aeromexico-operated flight because of how they buy bulk seats.
Check your passport expiration today. Mexico requires it to be valid for the duration of your stay, but many airlines won't let you board if you have less than six months left. Better to find out now than at the gate.

If you're flying with a pet, call the airline immediately after booking. Aeromexico has strict limits on how many animals can be in the cabin per flight, and those spots fill up months in advance. Get your "PETC" code added to your reservation as soon as the payment clears.
