Aeromexico allows passengers to check in online starting 48 hours before departure for domestic flights and 24 hours before departure for international flights. Online check-in closes one hour before domestic flights and two hours before international flights. Passengers can check in by visiting the Aeromexico website or using the mobile app. During online check-in, travelers enter their booking reference or frequent flyer number, select or change seats, and receive their boarding passes, which they can print or save on their smartphones. Mobile boarding passes make the process easier by allowing quick access at security checkpoints and boarding gates. For those who prefer or need to check in at the airport, Aeromexico provides check-in counters at all airports served by the airline. The counters open two hours before departure for domestic flights and three hours before departure for international flights. They close 45 minutes before domestic flights and 60 minutes before international flights. Self-service kiosks are available at select airports, where passengers can check in, select seats, and print boarding passes without waiting in line. Passengers who have checked in online or on the app but need to check baggage can use the baggage drop counters at the airport. It is important to arrive early to allow enough time to drop off luggage and go through security. During check-in, passengers must present valid identification. For domestic flights, a government-issued photo ID is required, while international flights require a valid passport and any necessary visas. Aeromexico recommends arriving at least two hours before domestic flights and three hours before international flights to ensure enough time for check-in, baggage handling, and security checks. Passengers with special needs, such as reduced mobility or unaccompanied minors, should notify the airline in advance so that proper assistance can be arranged. Aeromexico’s staff at the airport and customer service are available to help with questions or problems during the check-in process. Checking in early is beneficial because it helps avoid last-minute issues and long lines at the airport. It also gives passengers more time to prepare and relax before their flight. Whether using online check-in, mobile check-in, self-service kiosks, or the airport counter, Aeromexico provides multiple options to suit different traveler preferences. By following the check-in timelines and arriving early at the airport, passengers can enjoy a smooth and stress-free start to their journey. Aeromexico’s clear policies and flexible check-in methods are designed to make travel easy and efficient for everyone. Overall, understanding how early to check in and what documents to have ready helps passengers avoid delays and ensures they get to their gate on time. Checking in online or via the mobile app is usually the fastest and most convenient method, but airport options are always available for those who prefer personal service or need extra help. Passengers should also check Aeromexico’s specific rules for their flight, as times and procedures may vary by route or airport. Following these guidelines helps ensure a comfortable travel experience and timely boarding. Aeromexico’s check-in policies support passengers in starting their trip without unnecessary stress or confusion.
