The Alaska Airlines flight change policy details the various fees that could be charged when you change your itinerary. The change in flight fee charged by Alaska Airlines is based on the price of your reserved ticket and any applicable fare changes. In accordance with the provisions of the ticket, Alaska Airlines will issue a refund or a credit for future travel if the purchased ticket fare is less on your new reservation. Please be aware that after the allocated 24-hour window, Saver fare travellers are not permitted to modify their flights. You won\t be eligible for a credit or a refund if you don\t alter your plans or notify Alaska Airlines of them in the allotted time prior to the departure of your journey.
