Changing a flight on Aeromexico involves different costs depending on several factors, including the fare type you purchased, the destination of your flight, and the timing of your change. Aeromexico offers various fare classes, and each class has its own policy regarding flight changes. The most restrictive is the Basic fare, which does not allow any changes. If you purchase a Basic fare ticket, you will not be able to modify the date, time, or destination of your flight. This fare is ideal for travelers who are certain of their plans and do not anticipate any changes. However, for travelers who require flexibility, the Classic, AM Plus, Premier, and Flexible fares provide options for changes with associated fees. For flights within Mexico under the Classic fare, if the change is made more than eight days before departure, the change fee is approximately 700 Mexican pesos. If the change is made within seven days before departure, the fee increases to about 1000 pesos. For international flights under the Classic fare, such as those to the United States and Canada, the fee is around 4020 pesos. Flights to Europe and Asia have even higher fees, averaging about 6030 pesos. For destinations in Central America, the Caribbean, and South America, the change fee is typically around 4020 pesos. These fees are standard per passenger and per flight segment. The AM Plus fare, which includes benefits like extra legroom and priority boarding, has a similar fee structure to the Classic fare. Changes within Mexico follow the same rule of 700 pesos if changed more than eight days in advance and 1000 pesos if changed closer to the departure date. International change fees also mirror those in the Classic fare, ranging from 4020 pesos to 6030 pesos depending on the destination. Premier fare tickets, which offer premium services and more comfort, also allow changes but still include a fee unless you have chosen a Flexible fare. For domestic Premier fare changes in Mexico, the fee is again 700 pesos if changed early and 1000 pesos if changed later. International Premier fares have change fees in the same range as Classic and AM Plus, generally starting from 4020 pesos and increasing with distance and route complexity. The Flexible fare is the only fare that allows free changes with no additional fees for changing the flight, regardless of the timing. However, even with a Flexible fare, if the new flight you select is more expensive than your original booking, you will need to pay the fare difference. This applies to all fare classes, meaning that while some may not charge a fee for making a change, the difference in cost between your original and new ticket must still be paid if the price is higher. In some cases, if the new flight is cheaper, the difference may not be refunded, especially with non-refundable fares. Another factor to consider is that Aeromexico has a no-show policy. If you do not show up for your flight and do not cancel or change it ahead of time, you forfeit the entire ticket and receive no credit or refund. Therefore, it is important to make changes in advance if your plans change. If you booked your flight through a third-party travel agency or an online travel site, you may need to contact them directly to make any changes, and additional fees or rules might apply based on their policies. Aeromexico may not be able to change these bookings directly. When changing a flight, travelers must also consider the method of booking and the availability of seats on the new flight. If the class of service is not available on the new date, the fare may be higher, leading to a more expensive change. Aeromexico also occasionally offers fare sales or promotions, and tickets purchased during these times may have additional restrictions, so reviewing the fare rules at the time of purchase is essential. In summary, the cost to change a flight on Aeromexico ranges from no fee under the Flexible fare to several thousand pesos under Classic, AM Plus, or Premier fares. Domestic flight change fees typically range between 700 and 1000 pesos, while international change fees can range from 4020 to 6030 pesos depending on the destination. All changes are subject to availability and potential fare differences. The key to minimizing change costs is booking a fare that matches your travel needs and being aware of all related terms and conditions.
