I am thinking I need to cancel my trip scheduled for November 4-14 due to my financial situation..i booked with the wanna get away fare on SW and I understand I will get credits for a future trip..and I have one year to use those credits..i am confused on one thing though..do i actually have to FLY by that one year date or just BOOK a flight by then? My friend and I are planning to go to FL but not sure exactly when yet..I'm hoping it'll be in Feb but we are not sure..thanks!
