To check in for a LATAM Airlines flight, you can use online check-in via the LATAM website or mobile app. Online check-in typically opens 48 hours before your flight and closes 1 hour before domestic flights and 2 hours before international flights. You will need your booking reference or ticket number and your last name. Checking in for a LATAM Airlines flight is a convenient and flexible process that can be done through several different channels depending on your travel preferences and itinerary. The most popular method is online check-in, which becomes available 48 hours before the scheduled departure of your flight. You can complete this process either on LATAM’s official website or through the LATAM Airlines mobile app. During online check-in, you’ll be able to enter necessary travel information, such as passport or ID details, select or change your seat (if applicable), and add any additional services like extra baggage. Once completed, you can download your boarding pass to your mobile device or print it for use at the airport. Online check-in is typically available until 2 hours before the flight, although it’s always advisable to complete the process as early as possible to secure a good seat and avoid any last-minute stress. In addition to standard online check-in, LATAM also offers an Automatic Check-in feature for eligible travelers who booked their tickets directly through LATAM. With this service, the airline will automatically check you in 48 hours before departure and send your boarding pass via email or through the app. This eliminates the need for manual check-in and simplifies the process further, especially for frequent flyers or business travelers who are short on time. However, not all flights or fare types may qualify for automatic check-in, so it’s best to verify your booking details in advance. If you're unable to check in online, LATAM provides self-service kiosks at most major airports. These kiosks usually open about 3 hours before international flights and 2 hours before domestic or regional departures, closing around 1 hour prior to takeoff. At the kiosk, passengers can check in using their booking reference or frequent flyer number, print their boarding pass and baggage tags, and proceed directly to the bag drop counter if they have checked luggage. This option is especially helpful for travelers who may need to make last-minute changes or did not have internet access beforehand. For those who prefer a more traditional experience, LATAM’s airport check-in counters are also available. These counters open around the same time as the kiosks—generally 3 hours before international flights and 2 hours before domestic ones—and close about 60 minutes prior to departure. Airport agents can assist with a variety of needs including special service requests, documentation checks for international travel, and managing excess baggage fees. Passengers with complex itineraries, infants, or those requiring mobility assistance are advised to use counter check-in to ensure all travel needs are met properly.[1_86 6 55 111 86 To ensure a smooth journey, LATAM recommends that travelers arrive at the airport at least 3 hours before international flights and 2 hours before domestic flights. This allows ample time for security screenings, baggage drop-off, and getting to the departure gate. By taking advantage of LATAM’s flexible check-in options—whether online, through the app, at a kiosk, or at the airport counter—passengers can enjoy a seamless start to their travel experience.
