Aeromexico allows free cancellation within 24 hours of booking if the booking is made at least seven days before the flight. This applies to most fare types but excludes group bookings, tickets bought with miles, and third-party bookings. After 24 hours, cancellation fees depend on the fare type. Basic, Classic, AM Value, and Comfort fares are generally non-refundable and non-changeable. Flexible and Premier fares allow free cancellation at any time before departure. Cancelling within 24 hours of departure may incur fees from $100 to $500 depending on fare and route, and some fares do not permit last-minute cancellations. In cases of involuntary cancellations such as weather or government restrictions, Aeromexico may waive fees and offer refunds or rebooking. Passengers with emergencies or medical reasons may get refunds with documentation. Refund times vary by payment method: credit card refunds take 7 to 10 business days, cash or check refunds may take up to 25 days. Cancellations should be made through Aeromexico’s official channels. Third-party bookings must be cancelled through the agency. Overall, passengers have 24 hours to cancel risk-free if booked early, but fees and restrictions apply after that depending on fare rules. It is important to check fare conditions and contact Aeromexico for help with cancellations and refunds.
