Changing a flight on Aeromexico can involve different costs depending on the fare type, route, and timing. For Basic fare tickets, changes are not allowed. If you want to modify your travel plans, you would need to cancel and buy a new ticket, which may cost more. For Classic fare, flight changes are allowed but come with a fee. On domestic routes within Mexico, the fee is around MXN 700 if changed more than 8 days before departure and MXN 1,000 if changed within 7 days of the flight. For international flights, like those to the United States or Canada, the change fee is approximately $210 USD, while for Europe or Asia it may reach $300 or more. If the new flight is more expensive, you must also pay the difference in fare. AM Plus fare allows changes with a similar fee structure to Classic fare. Premier fare tickets offer greater flexibility, with no change fee, but passengers still have to pay any fare difference. Flexible fares offer the most convenience, allowing unlimited changes without penalties, as long as the new flight has available space and the fare difference is covered. Premier Light fares allow changes for a fee as well, usually close to the $210 USD mark on international routes. It's important to remember that the closer you are to the departure date, the higher the fee might be, especially for domestic flights. Also, all changes are subject to availability. Flight changes can be done through Aeromexico’s website, app, or customer service. Fees are generally charged per passenger and per segment. Understanding the type of fare you purchased is essential before planning a change. If you booked through a third party or travel agency, additional rules or fees may apply. Overall, Aeromexico’s change policy is strict on cheaper fares but offers flexibility on premium or flexible options. Always review the specific fare conditions at the time of booking or before making changes.
