Making travel arrangements can be difficult; difficulties frequently occur. On the day of your reservation, if you believe you might be ill, decide not to go, or experience an emergency. Alaska Airlines makes it rather simple to change or cancel flights online. To get a full refund, you must cancel your flight within 24 hours after making your reservation. Remember that once the 24-hour timeframe has passed, certain limitations, especially for fare savings, come into force. If you choose to cancel a reservation made with miles, Alaska Airlines cancellation policy will be followed and the miles will be returned to your account. You will receive a credit for an unused ticket prior to the flight's departure if you purchased a refundable fare, in which case it will be redeposited.
