How to check in Aeromexico Visit the AeroMexico website or mobile app, enter your booking reference or ticket number, and then follow the on-screen instructions to complete online check-in. Alternately, get to the airport early, look for AeroMexico check-in desks or kiosks, and provide your reservation information or passport for help.

Specific guidelines may apply, so check AeroMexico’s requirements for your particular airport and destination.
