Changing a flight on Aeromexico involves different costs depending on the type of fare you purchased, your destination, and how close to departure you are when making the change. Aeromexico offers various fare classes such as Basic, Classic, AM Plus, Premier, and Flexible, and each has its own rules for modifications. Basic fare is the most restrictive and usually does not allow any changes; if you need to make a change, you would have to forfeit the ticket and purchase a new one. Classic, AM Plus, and Premier fares allow changes, but you will be required to pay a fee along with any difference in fare. For domestic flights within Mexico, if you change your ticket more than eight days before the flight, the fee is typically around 700 Mexican pesos. If you make the change within seven days of departure, the fee can go up to 1000 Mexican pesos. For international flights, change fees are much higher and can range from 4020 to 6030 Mexican pesos, depending on the destination and fare class. In all cases, even after paying the change fee, you are responsible for paying the difference in fare if the new flight is more expensive than the original. If the new flight is cheaper, depending on the fare rules, you may or may not receive a refund or travel credit for the fare difference. Flexible fares, which are usually the most expensive when initially purchased, provide the benefit of unlimited changes without any additional fees, though you still have to pay the fare difference if applicable. This makes Flexible fares ideal for travelers whose schedules are uncertain. Changes can be made through Aeromexico’s website, mobile app, airport counters, or customer service. It’s important to make changes in advance, as same-day or last-minute changes usually result in higher costs. Additionally, if you booked your ticket through a third-party agency or travel site, you might have to contact them directly to make changes, and they might apply their own service fees. For special fares or promotions, different rules may apply, and in some cases, no changes are allowed regardless of the timing or reason. It’s always best to review the conditions of your specific fare class at the time of booking, so you know what to expect if plans change. In summary, the cost of changing a flight on Aeromexico depends on when you make the change, what type of fare you purchased, where you are flying, and whether the new flight is more or less expensive than the original. Always consider these factors carefully before booking to avoid high fees or losing your ticket value.
