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 Angeles International Airport (AIFA), which is 35 kilometres or 22 miles away in Zumpango and has the airport code NLU.

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.
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.

There are plenty of money changers as well. The rates vary, so check them out first.
