Online Check-In

Online check-in begins 24 hours prior to departure time and ends 3 hours prior to departure time. If you are traveling with checked baggage, you must check-in at the ticket counter.

Whether you check-in online or in person, it is your responsibility to allow enough time to complete the security screening process at the airport and be present at the departure gate on time.

No refunds will be given for missed flights due to late arrival at the boarding gate regardless of whether you were already checked-in or have a confirmed seat.  Please see the airport information below for check-in times and security screening cutoff times.
