I wait for southwest every year. It is agonizing as they release them slowly. But in the past four years, I have averaged about 215 a person round trip, and I use my AMEX rewards points and usually get one free ticket. So for four of us, I spend about 757-800 or less. In 2002 I spent 686 on four tickets.
I am waiting for the Feb. rates to come out because my DH goes to the Daytona every year, and hotel, rental car are booked, just not the airfare.
I wish it was spring break already.....
