To qualify for a same day confirmed change:

You must be holding confirmed reservations and tickets for flights operated by Alaska Airlines.
You must request the change prior to the departure of your original flight.
You must keep the same origin, destination, thru, and connection cities. Co-terminal changes are not allowed.
Your new desired flight must depart on the same calendar day as your originally scheduled flight.
