If you're flying with LATAM Airlines and wondering, “How long before my LATAM flight can I check in?”, the answer depends on your preferred method—online or at the airport. LATAM makes the check-in process easy and flexible by offering both online and in-person check-in options. For most flights, online check-in opens 48 hours before the scheduled departure time and closes one hour prior to departure for domestic flights, and up to 75 minutes prior for international flights. This gives passengers ample time to complete check-in from the convenience of their home or mobile device.

LATAM recommends using the online check-in feature through its website or mobile app. This allows you to access your boarding pass, choose your seat, and manage baggage options with just a few clicks. This process is especially convenient for those who are traveling with hand luggage only, as it allows you to head directly to security upon arrival at the airport. By checking in early online, you can save time and avoid long lines at the airport counters.

For travelers who prefer to check in at the airport, LATAM's airport check-in counters typically open two to three hours before departure, depending on whether it’s a domestic or international flight. For domestic flights, it’s advisable to arrive at least 90 minutes prior, while for international travel, arriving at least 3 hours before departure is recommended. This allows sufficient time for baggage drop, document verification, and going through security, especially in busy terminals or international hubs.

A key benefit of checking in early—whether online or at the airport—is securing your seat preference. LATAM allows passengers to select standard or premium seats during the check-in process. Those who check in late may find limited seat availability, especially on fully booked flights. Checking in early also provides peace of mind, as you’ll receive any important updates on flight status, gate changes, or delays directly via email or SMS.

For those flying on connecting routes or with codeshare partners, early check-in becomes even more essential. LATAM's system typically allows you to check in for the entire journey in one go, including all flight segments, ensuring a smoother travel experience. In case of baggage check for international itineraries, you may still need to visit the airport counter, but online check-in helps reduce overall wait time.

In summary, LATAM Airlines offers check-in as early as 48 hours before your flight, with closing times ranging from 1 to 1.5 hours before departure depending on whether the route is domestic or international. Travelers are encouraged to check in online for faster processing and more control over their travel preferences. If you have any questions or need assistance with your itinerary, LATAM customer service is available at +1-866-551-1186 to provide real-time support and help you stay on schedule. Early check-in is the best way to start your journey with LATAM, ensuring comfort, convenience, and a hassle-free airport experience.
