Since Southwest now owns Airtran, can I cancel my SW flight and use the credit to book an Airtran flight? Airtran has a later flight (8:45pm compared to 7:10pm) on the day we come home, and we'd like to max our park time
. However, I've already booked SW and would have to cancel. We don't plan on taking another flight within the next year, so I'd lose that $$ if I can't transfer it....
