Look, everyone wants that perfect shot of the Palacio de Bellas Artes or a plate of steaming al pastor tacos in Roma Norte, but getting there is the part that usually gives people a headache. Finding flights to Mexico City shouldn't feel like a part-time job. Honestly, the algorithms are basically rigged to show you the most expensive options the moment you show a hint of interest. Mexico City’s Benito Juárez International Airport (MEX) is one of the busiest hubs in Latin America, and because of that, the pricing is chaotic. It fluctuates based on everything from seasonal pilgrimage dates to random business conferences in Santa Fe.
You've probably noticed that prices jump fifty bucks just by refreshing your browser. It’s annoying.
The reality is that Mexico City isn’t just a vacation spot anymore; it’s a global business titan and a digital nomad magnet. This means the old "buy on a Tuesday" advice is mostly dead. If you’re looking at flights to Mexico City, you have to understand the layout of the land—not just the airlines, but the actual physical constraints of the airport and the secondary options that most tourists completely overlook because they’re stuck on Expedia.
Why the Timing of Your Mexico City Flight Actually Matters
Most people think of "high season" as summer or Christmas. For Mexico City, it’s weirder than that. You have the Formula 1 Grand Prix in late October, which sends hotel and flight prices into the stratosphere. Then there’s Dia de los Muertos right after. If you're trying to book a flight during the first week of November, you're essentially competing with the entire world.
Conversely, the city empties out during Semana Santa (Holy Week). While coastal towns like Cancun are packed, the capital gets quiet. It’s one of the best times to find cheaper seats, though you’ll find some local shops closed.
Airfare to MEX is also heavily influenced by the "business traveler" effect. Since it’s a massive financial center, flights arriving Sunday night or Monday morning are consistently pricier. If you can swing a Tuesday arrival or a Saturday departure, you’ll often see a price drop that covers a few nights of high-end dinners in Polanco.

The Aeromexico vs. Volaris Dilemma
You basically have two worlds when flying into MEX. You have the full-service experience with Aeromexico, which is part of the SkyTeam alliance. If you have Delta status, this is usually your go-to. They fly out of Terminal 2, which is slightly more modern but often feels like a maze.
Then you have the low-cost carriers (LCCs) like Volaris and VivaAerobus.
Here is where people get burned.
Volaris will show you a flight for $150 round trip from Los Angeles or Chicago. You think, "Perfect, I've beat the system." But then you realize that price doesn't include a carry-on. Not a checked bag—a carry-on. By the time you add a bag and a seat selection, you’re often at the same price as a United or Aeromexico ticket, but with less legroom and a Terminal 1 arrival that feels like a 1970s bus station. Terminal 1 is massive, sprawling, and frankly, a bit of a trek to navigate if you're in a rush.
Have You Considered AIFA (NLU)?
This is the big secret most travelers haven't caught onto yet. In 2022, the government opened the Felipe Ángeles International Airport (NLU), commonly known as AIFA. It’s located further out in Zumpango.

Most people avoid it.
They avoid it because it’s about an hour (or more in bad traffic) from the city center. However, because the government is desperate to get people to use it, the airport taxes (TUA - Tarifa de Uso de Aeropuerto) are significantly lower than at MEX. If you are looking for flights to Mexico City and the prices at the main airport are hitting $600, check AIFA. You might find a flight for $250. Even with a $50 Uber or a long bus ride, you’re still hundreds of dollars ahead.
Just keep in mind that international connections at AIFA are still growing. It’s mostly domestic or specific US routes (like Houston or Dallas on certain carriers).
Understanding the TUA: The Invisible Fee
In Mexico, the advertised price isn't always what you pay at checkout. There is a specific tax called the TUA. On many low-cost carrier websites, they’ll show you a "base fare" of maybe $10 USD. It looks like a steal. Then, at the very last screen, they tack on $50-$60 for the TUA.
- MEX (Benito Juárez): Has some of the highest TUA rates in the country.
- AIFA (Felipe Ángeles): Significantly lower TUA.
- TLC (Toluca): Another alternative airport that occasionally hosts low-cost flights.
Always make sure you’re looking at the "Total" price before you get your heart set on a specific flight. If you're flying from Europe or deep South America, this is usually bundled in, but for North American transborder flights, it’s often broken out to make the price look lower than it is.

The Connection Game
If you're flying from a smaller US city, don't just search for a direct flight. Sometimes it’s cheaper to fly to San Antonio or Houston and then take a separate VivaAerobus flight into Mexico City. This is called "self-transferring."
It’s risky.
If your first flight is late, the second airline doesn't care. They won't rebook you for free. But if the price difference is $400, many people take the gamble. Just give yourself at least a four-hour layover to clear customs and immigration, because the lines at MEX can be legendary.
Speaking of customs: Mexico has moved toward a digital system for many nationalities, meaning you might not even get a stamp in your passport anymore. You just scan your way through the gates. It’s much faster than it was three years ago, but it still varies depending on which terminal you land in.
Best Tools for the Hunt
Google Flights is still the king for broad searches because of its "Explore" feature. You can put in "Mexico City" and see a calendar of prices. But once you find a price you like, go to the airline's direct website. Third-party booking sites like Kiwi or Gotogate can be a nightmare if a flight is canceled. Mexico City weather—especially during the rainy season from June to September—can cause afternoon delays due to heavy thunderstorms. If your flight is delayed or canceled, dealing directly with Aeromexico or Delta is a thousand times easier than trying to reach a call center in a different time zone.
Practical Steps for Booking Your Trip
- Check both airports: Always compare MEX and NLU (AIFA) in your search engine. Use the "nearby airports" checkbox.
- Monitor the TUA: If a price seems too good to be true, it probably doesn't include the airport tax yet.
- Book 5-8 weeks out: For international flights to Mexico City, this seems to be the sweet spot. Last-minute fares here are brutal because of the high volume of business travel.
- Consider the terminal: If you have a choice, Terminal 2 is generally a more pleasant arrival experience, though Terminal 1 has better public transport links (like the Metro) if you're traveling light.
- Verify your baggage: Especially on Volaris or VivaAerobus. They will weigh your carry-on at the gate. If it’s over their strict limit, they’ll charge you $50+ on the spot.
Once you land, skip the "official" taxi stands inside the terminal if you want to save money. Walk to the designated ride-share pickup zones for Uber or DiDi. It's usually half the price of the authorized airport cabs, though you might have to walk a bit further through the terminal to find the specific door where they're allowed to pick up. Stick to your apps and you'll get to your hotel without the "tourist tax" markup.
