Aeroméxico check-in Online check-in and airport check-in are the two check-in options provided by AeroMéxico. The airline’s website or mobile app, which is normally accessible 48 hours before the trip, allows passengers to check in online. Alternatively, travellers can use the AeroMéxico self-service kiosks or designated counters at the airport to check in. Particularly for foreign travel, enough time should be allowed before the flight, and passengers should have their required travel documents with them. The baggage policies of AeroMéxico apply to checked bags. It’s vital to examine the specific check-in guidelines and deadlines in advance as they may change based on the departing airport and final destination.
