Changing your flight on Aeromexico is a simple process that can be done online, by phone, at the airport, or through an Aeromexico office. To change your flight online, go to the Aeromexico website, click on “My Trips,” enter your booking number and last name, select your flight, choose a new date or time, and pay any fare difference or change fees. You’ll receive a confirmation email once the change is complete. You can also call Aeromexico’s customer service at +1-833-845-1858 (USA/Canada) or +1-833-845-1858 (Mexico) and provide your reservation details to make changes with the help of an agent. If you prefer in-person assistance, visit an Aeromexico ticket counter at the airport or an Aeromexico office. Fees and policies vary depending on your fare type. Basic fare tickets are generally non-changeable. Classic, AM Plus, Premier, and Flexible fares allow changes, but fees and fare differences may apply. Changes made within 24 hours of booking are usually free, but after that, charges range from $200 to $310 USD depending on the destination and time of change. If the new flight is more expensive, you must pay the difference. Aeromexico also allows same-day flight changes on most fares except Basic. You must visit the airport at least three hours before your original flight, and same-day changes depend on seat availability and may include a fee. To avoid issues, check your fare conditions before booking, act quickly if you need to change your flight, and keep all confirmation emails and receipts. Always verify the latest rules on the Aeromexico website or contact customer support, especially for international flights or special circumstances.
