Travelers are permitted to cancel their reservations up to 120 minutes prior to the scheduled departure of the aircraft, but if they wish to avoid paying a cancellation fee, they must do it at least seven days or twenty-four hours in advance. Only Alaska Airlines' official website and its application will accept cancellations of reservations. Information in full regarding Alaska Airlines' cancellation policy: When you successfully cancel a ticket, you can then book another flight using the same login information or email address. Passengers have the right to cancel their reservation at any time, from any location, for any reason, including illness or the death of a close relative. In such a circumstance, they will receive a full refund without incurring any cancellation fees. Any promotion or discount code won't be valid during the booking cancellation period.
