Yes, LATAM Airlines does allow passengers to select their seats in advance for most flights. This feature can be particularly beneficial for travelers who wish to ensure they are seated next to companions, have extra legroom, or prefer a specific location on the aircraft. Seat selection is typically available during the online check-in process, which generally opens 48 hours before the flight departure. Additionally, passengers may also have the option to choose their seats while booking their tickets through LATAM's website or mobile app.
It is important to note that some fare types may not include complimentary seat selection, and in such cases, a fee might apply. For more detailed information about seat selection policies, passengers are encouraged to check the relevant sections on LATAM Airlines’ official website, where they can find the most current and comprehensive guidance.
