How does a same-day flight change work with Southwest Airlines?

Southwest same-day benefits depend on the fare product and live seat result shown for the booking. Distinguish a confirmed replacement from standby, keep the original segment protected until the new status is clear and verify the airport pair. If a requested option changes date or routing, price it as an ordinary Southwest change rather than promising same-day treatment. Retrieve the Southwest confirmation and identify the fare product printed on the booking before choosing Change or Cancel. For this same day change decision, reconcile Southwest confirmation with same-day request-window timestamp, then compare Southwest flight-credit against original flight protection until clearance. Record the new Southwest confirmation, the form and owner of any remaining value, and the status of every traveler on the reservation.
