Getting around MEX

Terminals

Terminals 1 and 2.

Changing terminals

Aeroméxico flies from Terminal 2. The Aerotrén links the terminals for passengers with a boarding pass, and you go through security again.

Passport control and transfers

Arriving from abroad, you clear Mexican immigration and customs at your first Mexican airport, then recheck bags for a domestic connection.

MEX connection FAQ

Airlines set their own official minimums at MEX and only sell connections that meet them, so a one-ticket itinerary is always "legal". In practice we recommend at least 55 min for a same-terminal connection, 1 h 30 min when you change terminals and 2 h 20 min after an international arrival.
