Hi all - here's an update on our thinking. It is spring break so we don't want to get out of school another day early. In fact, we are hoping for a late flight that we can go directly from school or just miss an hour, which lowers our chances of a good price.
We aren't crazy about renting a car for the last leg of our trip, but it is an option if we get to the end of our rope. There are a couple of connecting flights through DFW that are closer to $400. But ... on Tuesday, AA lowered the $569 direct flights to $509 and my wife got excited that maybe waiting will pay off. (she's thinking that the flights aren't selling out at that price) Some crazy things we have discovered in this were that the prices are so high that some flights have cheaper first class seats than regular seats (!) and for some flights, we can buy points for it cheaper than the price!!
We have the AA credit card where we get most of our points from and my wife uses them for work travel. The annual fee makes it worth it for the free bag. That, along with her TSA pre-approval makes us want to get all 4 of us on the same reservation, either with points or dollars, to take advantage.
So hang on for the gamble -- it's looking like we might be waiting until SW announces their prices.
