Aeromexico charges to change a flight date based on the type of fare purchased, the destination, and the timing of the change. If the ticket is a Basic Fare, changes are not allowed at all, meaning the passenger cannot modify the date under any circumstance. For Classic Fare, changes are permitted but with a fee. On domestic routes within Mexico, the change fee is approximately 700 pesos if the change is requested more than eight days before departure. If the change is made within seven days of the flight, the fee increases to around 1,000 pesos. For international flights, the change fee can range from 200 to 320 US dollars, depending on the region and how close to the departure the change is made. AM Plus fares follow the same rules and fees as Classic Fare. Premier Fare allows passengers to change their flight date without paying a change fee, but the passenger must cover any difference in fare between the original and new flight. Flexible Fare offers the most freedom, allowing unlimited date changes without any extra charge, although fare differences still apply. Regardless of fare type, if the new flight is more expensive than the original, the passenger must pay the difference in price. If the new flight is cheaper, Aeromexico does not typically refund the difference. There is a special policy for travelers whose flights originate in the United States or Canada. If the booking is canceled or changed within 24 hours of purchase and the flight is more than seven days away, the change can usually be made at no cost. Passengers should also be aware that failing to show up for a flight without notifying the airline in advance may result in the loss of the entire ticket value, and further changes may not be allowed. Aeromexico calculates fees in the local currency where the ticket was purchased, and these fees can vary depending on exchange rates and policy updates. It is always better to make changes as early as possible, as last-minute changes tend to carry higher fees. In all cases, passengers should check the fare conditions provided at the time of booking, which outline the specific rules and fees applicable to their ticket. Choosing a more flexible fare at the time of booking may cost more upfront but can save money and stress if plans change later. Frequent flyers or members of Aeromexico’s loyalty program may also receive additional flexibility or reduced change fees depending on their membership level. All flight changes are subject to seat availability, and if no seats are available in the original fare class, a higher fare class may be required. Therefore, while Aeromexico does allow flight date changes for most fare types, the exact cost depends on many factors, and understanding the rules in advance can help avoid unexpected charges.
