Tips if you have never flown Southwest:
-line up by boarding number
-seats are chosen first come first serve, choose anywhere!
-generous reimbursement for giving up your seat but the ticket agents may not be so forthright about the fastest alternative to bring you home
I wound up with $400 in flight credit and only had to arrive an hour later. I was happy with my flight and didn't mind being forced to the middle as I was traveling solo.
