Checking in for LATAM Airlines is a straightforward process that offers multiple convenient options for travelers. The most popular and efficient way to check in is through online check-in, which opens 48 hours before your scheduled departure time and closes 1 hour prior to departure for domestic flights and 2 hours before international flights. You can complete online check-in on the official LATAM Airlines website or via their mobile app. To check in online, simply enter your booking reference and last name to access your reservation. Once logged in, you can select or change your seat, add baggage, and obtain your boarding pass. After completing online check-in, passengers can either print their boarding pass or save a digital copy on their smartphone, which expedites the process at the airport. For travelers who prefer airport check-in, LATAM Airlines provides dedicated check-in counters that typically open 3 hours before departure and close 1 hour before domestic flights and 2 hours before international flights. It’s advisable to arrive at least 2 hours before domestic flights and 3 hours before international flights to allow sufficient time for check-in, baggage drop, security screening, and boarding. LATAM also offers self-service kiosks at many airports, enabling passengers to check in quickly, print boarding passes, and print baggage tags without waiting in long lines. After kiosk check-in, passengers can proceed to the bag-drop counter if they have checked luggage. These kiosks usually open alongside or shortly after the airport check-in counters and close approximately 45 minutes before departure. For travelers flying in premium cabins or those who are LATAM Pass elite members, priority check-in counters are available, which help reduce waiting times and provide a smoother check-in experience. Passengers should also be aware of baggage policies and ensure that all travel documents, including visas and passports, meet the destination requirements to avoid delays during check-in. For codeshare flights operated by partner airlines, it is recommended to check the specific check-in rules with the operating carrier, as they may differ. If you have connecting flights, allow adequate time between connections to complete any additional check-in or baggage procedures. Late check-in may result in denied boarding, so it’s important to adhere to LATAM Airlines’ check-in deadlines. For maximum convenience and to avoid airport queues, online or mobile check-in is highly recommended, especially during peak travel periods. In summary, LATAM Airlines check-in opens 48 hours before departure via online platforms, closes 1 hour before domestic and 2 hours before international flights, while airport counters open 3 hours prior and close 1 to 2 hours before flight time. Using LATAM’s self-service kiosks and priority check-in counters can expedite the process. Arriving early, completing online check-in when possible, and preparing all necessary travel documents will help ensure a smooth and stress-free start to your journey.
