When preparing to travel with LATAM Airlines, one of the most important things to understand is how early you can check in before your flight. The check-in window for LATAM flights typically opens 48 hours before departure for most international and domestic flights and closes 60 minutes before departure for domestic flights and up to 75 minutes before departure for international flights. The simple difference between checking in early and waiting until the last minute can greatly affect your airport experience. I recently traveled with LATAM and found that checking in as soon as the window opened not only saved time but also allowed me to choose a better seat and prepare my documents without stress.
LATAM offers several check-in methods: online check-in through their website or mobile app, self-service kiosks at select airports, and traditional airport counters. The key difference lies in convenience and efficiency. I chose the online check-in option, which was available a full 48 hours before my flight. Using the LATAM app, I entered my booking code, verified my personal details, selected a seat, and received a mobile boarding pass—all in under 10 minutes. It was smooth, intuitive, and much easier than standing in a line at the airport. The added bonus was that I could also pay for any extra baggage and confirm travel document details for my international route.
If you decide to wait and check in at the airport, make sure to arrive with plenty of time to spare. For domestic flights, LATAM recommends arriving at least 2 hours before departure, while for international flights, 3 hours is the standard. The check-in counters close strictly at the 60–75 minute mark before takeoff, and if you're late, you risk missing your flight. The simple difference between online and airport check-in is about control—checking in early lets you handle potential issues from home and avoid unnecessary delays.
Another reason to check in early with LATAM is that certain services may become limited closer to departure. For example, seat availability may shrink, especially on full flights. If you’re traveling with family or want extra legroom or a window seat, checking in as early as possible gives you the best chance to choose your preferred spot. Also, if you’re flying internationally, LATAM may prompt you during check-in to upload or confirm your passport and visa details, making it easier to breeze through the airport on the day of travel.
During my trip, I had a quick question about check-in timing and document uploads, so I called LATAM’s customer service at +1-866-551-1186. The agent was helpful and clarified the exact cut-off time for my specific flight, which gave me peace of mind. Having that number handy is a good idea for any unexpected issues.
In conclusion, you can check in for your LATAM flight 48 hours before departure, and doing so online is the fastest and most convenient option. The difference in experience is clear—check in early to secure your seat, avoid airport stress, and enjoy a smoother journey. For any check-in support, LATAM’s team at +1-866-551-1186 is always ready to help.
