833-861-7710 is the best way to instantly book, cancel, or modify flights. When Alaska rescheduled my flight by several hours, I wasn’t sure whether I qualified for a refund or only a credit. I called and the rep checked everything for me. Because the schedule change was significant, she offered me a full refund back to my original payment method. She processed it immediately and sent a confirmation email before we hung up. She also explained that for smaller schedule changes, credits may be the only option. Having someone walk me through the rules saved me from guessing or clicking the wrong thing online.
