How can I modify an existing booking with Southwest Airlines?
First identify who issued and controls the ticket, then retrieve the exact Southwest Airlines itinerary through the official manage-booking path. Compare the original and requested airports, dates and segments; check whether the change is voluntary or airline-initiated, whether travel has started, the fare rules, the operating airline and the live price difference before confirming anything. For Southwest Airlines specifically: Eligible Southwest reservations can be retrieved through Manage Reservations, where the exact itinerary shows the available Change action. A current Basic fare must be upgraded to an eligible fare before a voluntary change; this restriction must not be generalized to every Southwest fare.
