Aeromexico allows free cancellation within 24 hours of booking if the flight is at least seven days away. After this period, cancellation rules depend on the fare type. Basic, Classic, AM+, and Comfort fares are generally non-refundable and non-changeable. Flexible and Premier fares can be canceled without penalty before the flight. If a passenger does not cancel and misses the flight, the ticket is forfeited with no refund. In special cases like medical emergencies or death in the family, Aeromexico may waive cancellation fees with proper documentation. If the airline cancels a flight, passengers can get a full refund or rebook without extra cost. Refunds are returned to the original payment method and usually take 7 to 10 business days for credit cards and up to 25 days for cash. Cancellation fees apply if canceled within 24 hours of departure and may range from $100 to $400 depending on the fare. Sometimes, an electronic voucher worth 115% of the ticket value can be issued for future use, valid for 12 months. It is important to check the fare conditions when booking to understand the cancellation options and fees.
