Online check-in opens 24 hours before your scheduled departure and closes one hour prior for domestic flights and two hours before for international flights. To check in online, you’ll need to enter your confirmation number, last name, and departure city. Once you complete the check-in process, you can select seats, add baggage, and receive your boarding pass, which can be printed or saved digitally.
