LATAM vs Other Major Airlines: Check-In Comparison
LATAM Airlines allows online check-in between 48 and 72 hours before departure, giving passengers more flexibility than American Airlines, which opens check-in 24 hours prior, while Avianca opens at 48 hours. All three airlines support mobile boarding passes, making digital travel convenient across carriers.
When it comes to airport operations, LATAM and Avianca apply strict counter cut-off times, whereas American Airlines is generally more flexible. Seat selection during check-in with LATAM and American Airlines depends on the fare purchased, while Avianca offers more limited seat options at this stage. For baggage handling, LATAM and American Airlines integrate baggage declaration directly into the check-in process, while Avianca often manages baggage separately, which may add time at the airport.
