If you want to cancel your flight online, you can either do it online from your Aeromexico account or by calling on the cancellation number. For that, you first need to book a flight with the airlines. If you have booked your flight through any third-party agency, then you should preferably cancel your flight ticket through them.
What is the Aeromexico cancellation policy?
Firstly, you need to go to the official website of the airlines
Then go to the Manage Your Trip section where you can make changes in your travel itinerary.
If the booking is cancelled by the passenger, then a cancellation fee will be applicable according to the fare rules set by Aeromexico.
One can also make the cancellation through the Aeromexico reservations official site or can directly cancel the ticket and ask for a refund to be processed.
The amount that will be refunded will depend on the type of ticket booked by the passenger.
