How to Rebook A Canceled Flight on Southwest Airlines?
The rebooking process will vary depending on what segment of your vacation was cancelled by Southwest Airlines. So according to Southwest Airlines cancellation policy, if your flight is canceled before the trip, Southwest notifies passengers of a change in the travel schedule and assigns an alternative flight. But, if those plans don't work for you, you can alter them for up to 14 days without incurring additional fees.
But if Southwest cancels your flight during your trip, the best action is to contact customer care for a free rebooking.
