Anytime, you can get something that close to a holiday for under $100.00 it is worth it to me.
I booked my flights for the Saturday after Thanksgiving from BWI to MCO and back the following Saturday. With seat assignments, I got $192.00 round trip, non-stop both ways. I think that is pretty darn good.
And I am four months out and there are only about ten seats left on my flight going down. So I wouldn't wait.
