You can change a flight that is linked to a Companion's flight by following these steps:
Cancel the linked Companion's flight
Change your flight to the date/time/destination you want
Rebook the companion's flight
You can also call a Southwest Airlines Customer Representative at 1-800-I-FLY-SWA (1-800-435-9792) for help. If you have already cancelled the Companion's reservation and still can't make changes to your flight, we might be experiencing a delay.
