Seat Selection
You can select the seat you want or change seats during check-in. If all seats that can be reserved beforehand are already assigned, seats can be assigned at the airport. Free advance seat may be canceled if check-in is not completed 30 mins (domestic) or 70 mins (international) prior to departure.
International Check-In Rules
Accurate passport information and necessary travel documents (local address, etc.) must be entered. If passport information is not entered accurately, check-in may be denied based on pre-screening results. For flights arriving in the U.S., you need to enter the address of the place you will stay at in the U.S. (hotel) or your permanent residency status.
Group Check-In
Online check-in is available for group reservations, but the auto check-in service is not possible for group reservations.
Troubleshooting
1. 'Check-in denied' - Ensure accurate passport information is entered for pre-screening. 2. 'Seat changed' - Reserved seat may change due to airport status or aircraft changes. 3. 'Free advance seat canceled' - Complete check-in 30 mins (domestic) or 70 mins (international) prior to departure to keep the seat. 4. 'Mobile boarding pass not recognized' - Increase screen brightness.
