Flight time changes on the same calendar day as departure are considered Alaska Airlines same-day changes in accordance with Alaska Airlines flight change policy. By selecting the "Change Flight" tab during web check-in, mobile app check-in or airport kiosk check-in, you can request a flight change. All you have to pay is the same-day Alaska Airlines change fee, which ranges from $25 to $50 depending on the route. Passengers are not obligated to pay the fare difference. In addition, any flight time adjustments, such as an earlier or later departure schedule in both directions, must be made within 24 hours of purchase. Only a significant difference would be relevant. Alaska Airlines offers discount fares. No Saver fare adjustment is allowed. Passengers can only cancel their reservation and receive a full refund if they do so within Alaska Airlines' 24-hour cancellation window.
