The Alaska Airlines flight change policy offers flexibility for most travelers. Main cabin and first-class tickets can be changed without change fees, but passengers must cover any fare difference if the new flight costs more. Saver fares, however, are non-changeable and non-refundable. Flight changes must be made at least 24 hours before departure, but Alaska Airlines also provides a same-day flight change option for $25–$50, depending on the route. Travelers can modify flights through the Alaska Airlines website, app, or by contacting customer service. This policy ensures convenient options for travelers needing to adjust their plans.
