Aeromexico allows passengers to change or cancel flights based on fare type. Basic fares are usually non-changeable and non-refundable after 24 hours of booking. Classic, AM Plus, and Comfort fares allow changes with a fee, while Flexible and Premier fares offer free changes—though fare differences may apply. Changes made within 24 hours of booking (and if the flight is 7+ days away) are typically free. Cancellation fees vary but start around $200 USD for international routes. Refunds are usually processed within 7–14 business days. For quick assistance, contact OTA at 1-877-658-0437.
