This post deals with the logistics of how to get from Terminal 1 to Terminal 2 (and vice versa) at the Aeropuerto Internacional Benito Juárez (AICM), otherwise known as Mexico City Airport, airport code MEX.

Mexico City Airport has two terminals. Don’t forget to check which terminal your flights are arriving at or leaving from.
Mexico City has a new airport: The Felipe Ángeles International Airport (AIFA), which is 35 kilometres or 22 miles away in Zumpango and has the airport code NLU.
These are the questions being asked:
Can you walk from terminal 1 to terminal 2 in Mexico City Airport
Quick answer: No!
How far is Terminal 1 from Terminal 2 in Mexico City Airport?
It’s too far to walk and not safe!
What’s the best way to get from Terminal 1 to Terminal 2 at México City Airport
If you are arriving in Mexico at the Aeropuerto Internacional Benito Juarez, AICM, on an international flight and have a domestic transfer, you will have to go through immigration, collect your bags and check in for the next flight. Maybe at the same terminal, maybe not. Aeromexico uses Terminal 2, and the low-cost carriers like Volaris and Viva use Terminal 1
The TETSA BUS runs 24/7 from Terminal 1 to Terminal 2 and back again.
It stops at Puerta 7 / Door 7 at Terminal 1:

The fare is 25 pesos. Cash only. There are many ATMs located in the Arrivals Hall, with Citibanamex, BBVA, HSBC, Banorte represented.
It’s always a good idea to carry cash as a backup, wherever you travel. ATMs might run out of cash, especially on the weekend.
There are plenty of money changers as well. The rates vary, so check them out first.


Here is the route plan for the Tetsa Bus and, for reference, which airlines operate out of which terminals, though it is a little incomplete:





You can also use the Aerotrén for transfers free with a valid boarding pass.
Yes. The details are unclear though, for me. And i have never taken it. Never needed to. CDMX is always my last stop. This would be good if you are transferring internationally….. but if you have a domestic connection, you must pass through immigration. Or you check in in Terminal 1 for a T2 departure????
Just did this today and it’s legit!! Make sure your getting on the right bus TETSA and not another red bus and just put terminal 2 in your map so you don’t miss it
Thanks Gabi, for the thumbs up and confirmation that the TETSA bus is still running… Trevor
