To alter an Alaska Airlines flight, the passenger's name has to be given along with their reservation reference number. They also play an important role in checking reservations. Same-day flight changes are subject to availability and require a $50 fee. Only if the new flight is scheduled to depart on the same day that you took your last flight is it considered to be a day-to-day flight change. When checking in customers can ask for an immediate flight change. When checking in, select the Alaska Airlines flight change option at the airport kiosk. Passengers may confirm a change to a flight on the same day by calling an Alaska Airlines Customer Service Representative or the Alaska Airlines Reservation Team.
