AEROMEXICO Check-In: Everything You Need to Know Checking in with AEROMEXICO Check-In is a straightforward process that offers multiple options to accommodate different types of travelers and itineraries. The airline allows passengers to check in through various methods, including online, mobile, airport counter, curbside, and self-service kiosks. The most convenient and widely recommended method is online or mobile check-in, which opens 24 hours before the scheduled departure time and closes 45 minutes before departure for domestic flights, and 90 minutes before departure for international flights. This early check-in window gives passengers the opportunity to select or change their seats, add checked baggage, update frequent flyer information, enter passport details for international travel, and receive a digital boarding pass. Online and mobile check-in are especially useful for travelers with carry-on luggage only, as it allows them to skip airport counter lines and go directly to security. Boarding passes obtained online can be printed at home, sent via email, or stored digitally in a mobile wallet such as Apple Wallet or Google Pay. If you’re using the AEROMEXICO mobile app, you can also receive real-time notifications about gate changes, delays, and other flight updates. The app supports mobile check-in and digital boarding passes, which are accepted at nearly all major U.S. airports and many international destinations. For those checking baggage, even after completing online check-in, it is still necessary to arrive at the airport to drop off checked bags at the appropriate counter or bag drop area. AEROMEXICO requires checked baggage to be dropped off at least 45 minutes before domestic flights and 60 minutes before international flights. However, depending on the departure airport and the destination country, these deadlines may vary slightly. For example, in busy international hubs or when flying to countries with additional security procedures—like the United Kingdom or Israel—check-in and bag drop deadlines may be set even earlier. AEROMEXICO recommends that passengers arrive at the airport at least 2 hours prior to domestic flights and 3 hours before international flights to allow sufficient time for baggage drop, security screening, and reaching the gate. Gate areas typically close 15–30 minutes before departure, and late arrivals may result in denied boarding, even with a confirmed reservation. If you are unable or prefer not to check in online, airport check-in remains available and is staffed by AEROMEXICO personnel. The airport check-in counters typically open three to four hours before flight departure and close 45 minutes before domestic flights and 60 minutes before international flights, although some airports may set these deadlines earlier, especially during high-traffic periods. AEROMEXICO staff are available to assist passengers who need additional support—such as unaccompanied minors, travelers with disabilities, passengers flying with pets, or those with complex itineraries or travel documents that require manual verification. At most major U.S. airports, travelers will find clearly marked AEROMEXICO check-in zones. Elite status members, AAdvantage frequent flyers, First and Business Class passengers, and those with TSA PreCheck may have access to priority check-in lanes, which typically move faster than standard lines. Even when using priority lanes, travelers are encouraged to arrive with ample time to navigate possible congestion during peak hours or holidays. In addition to staffed check-in counters, AEROMEXICO also provides self-service kiosks at most domestic and international airport locations. These kiosks are available generally from three hours before departure until 45–60 minutes before takeoff. At a kiosk, passengers can check in, print boarding passes, select or modify seats, and print baggage tags. After tagging luggage, passengers proceed to the designated bag drop area to check their items. Kiosk check-in is convenient for travelers who did not check in online but are traveling on straightforward itineraries with no special service requirements. While kiosks can handle most standard check-in needs, passengers needing to verify documents, traveling with special baggage, or requesting upgrades may be referred to the staffed counters. At some international airports, kiosks may also support multilingual interfaces and biometric authentication, further speeding up the check-in process. Another unique service offered by AEROMEXICO at many U.S. airports is curbside check-in, a convenient option especially for travelers arriving by car or taxi. Curbside check-in is typically available from 4 hours until 45 minutes before departure, depending on the airport and terminal. Passengers can check in, tag bags, and drop luggage without having to enter the terminal first, provided they have a government-issued ID and a confirmed reservation. This service is available for both domestic and international flights, although international travelers may still be required to enter the terminal for passport control or documentation checks. Tipping is customary when using curbside baggage assistance in the U.S., though not mandatory. Curbside check-in can significantly reduce wait times, especially at airports with heavy foot traffic or limited indoor space. AMERICAN Airlines Check In For travelers who require special services, such as those flying with children, pets, wheelchairs, or medical equipment, it’s advisable to check in at the airport counter where AEROMEXICO staff can provide direct assistance. These passengers are encouraged to arrive at least three hours before departure, even for domestic flights, to ensure that all special handling procedures are completed without rushing. Unaccompanied minors must be checked in at the counter by a parent or guardian and cannot use online check-in. Similarly, passengers with service animals, mobility aids, or connecting flights through countries with additional documentation requirements (e.g., health certificates, visas) must check in at the airport. In the case of international travel, passengers should always verify the entry requirements of their destination country before checking in. Some countries require proof of return tickets, vaccination records, visa stamps, or digital travel authorizations that must be presented during check-in. AEROMEXICO may deny boarding if a passenger does not meet the destination’s documentation or health entry requirements. When traveling internationally, it is best practice to arrive at the airport at least three hours in advance, even if you’ve checked in online, to allow time for document validation, customs, and security. Boarding gates for international flights may also close earlier than for domestic flights, often 30 minutes before departure. Finally, AEROMEXICO also offers auto check-in for select domestic routes. When booking through the mobile app or if logged into your AAdvantage account, you may be given the option to be automatically checked in 24 hours before departure. Your boarding pass will be sent to your email or mobile app, and you can proceed directly to baggage drop or security. While this is a helpful time-saving feature, passengers should still confirm details manually to ensure that seat assignments, baggage preferences, and travel documents are all correctly registered. In summary, AEROMEXICO provides multiple check-in options to accommodate the varying needs of passengers across its global network. Whether you prefer the convenience of online and mobile check-in or require in-person support at the airport, knowing your check-in time windows is essential for avoiding delays and ensuring a smooth travel experience. For most domestic flights, check-in begins 24 hours before and closes 45 minutes before departure, while for international flights, check-in typically closes 90 minutes prior to takeoff. Airport counters, kiosks, and curbside check-in options add flexibility, while elite services and special assistance lanes help streamline the process for frequent or high-need travelers. Always consult your departure airport’s specific guidelines and American Airlines’ official policies before traveling, and give yourself enough time to complete all procedures especially during busy travel seasons or international journeys. By planning ahead and utilizing the right check-in method for your trip, you can board your AEROMEXICO flight with greater peace of mind and confidence.
