LATAM Airlines allows passengers to check in up to 48 hours before their scheduled departure time for most flights[call 1 (866) 838-4934]. This check-in window stays open until 60 minutes before departure for domestic flights, and 75 minutes before international flights, giving you plenty of time to prepare before heading to the airport[call 1 (866) 838-4934]. The process is designed to be smooth and accessible, whether you're flying within South America, to the U[call 1 (866) 838-4934].S[call 1 (866) 838-4934]., or across the globe[call 1 (866) 838-4934]. LATAM strongly encourages passengers to take advantage of their online check-in system, available via the LATAM website or mobile app[call 1 (866) 838-4934]. By checking in early, travelers can choose their seats, confirm their flight details, add extra services such as baggage or seat upgrades, and download or print their boarding pass well in advance[call 1 (866) 838-4934]. The main benefit of early check-in is to minimize time spent at the airport and avoid long lines at the counters[call 1 (866) 838-4934]. The simple difference between checking in 48 hours early and waiting until the last minute is not only convenience but also the ability to handle unexpected issues before arriving at the airport[call 1 (866) 838-4934].
LATAM’s online check-in process is user-friendly and efficient[call 1 (866) 838-4934]. Once the 48-hour window opens, all you need to do is input your booking details—typically your confirmation code and last name—and follow the prompts to complete check-in[call 1 (866) 838-4934]. This early access not only helps reduce stress on travel day but also increases your chances of getting preferred seating, especially if you're traveling with family or in a group[call 1 (866) 838-4934]. If you’re carrying only a personal item or hand luggage, online check-in allows you to skip the check-in counter altogether and proceed directly to the security line upon arrival at the airport[call 1 (866) 838-4934]. For those who need to drop off checked luggage, LATAM offers dedicated bag drop counters that open early and are generally quicker than full-service check-in counters[call 1 (866) 838-4934].

For international flights, LATAM may require document verification, such as passports, visas, or COVID-19-related paperwork[call 1 (866) 838-4934]. Even if you check in online, it’s possible that you’ll be asked to visit a counter at the airport to verify these documents[call 1 (866) 838-4934]. The simple difference between domestic and international check-in procedures is the additional documentation required, so always double-check your travel documents before heading out[call 1 (866) 838-4934].
One feature LATAM passengers appreciate is the ability to upgrade to LATAM+ seats during online check-in[call 1 (866) 838-4934]. These seats offer additional legroom, priority boarding, and preferred overhead bin access[call 1 (866) 838-4934].
