USAir has been high for December PIT/MCO. I'm looking for Dec 4 to 10. It's been about $290. I'm hoping frequent flyer will come out with some availability. The last time I checked FF only had 1 flight for each date, 6:00am deparatures with connections both ways. Air Tran is about $215 but they are always changing flight times, I don't want to book too far ahead. In May, they changed their 2:30pm non-stop return to 8:30am (other times available through Atlanta) right before I was going to book it. I lucked out and grabbed USAir with a resonable fare for the times I wanted. One day it dropped from $688 to $245, I bought the tickets and then it went back up to $688!
