I didn't see the ding for PIT Wed night, but I just booked the $68 fare for our trip down.
Now I'm hoping that Airtrans repeats the $59 fare for our trip back. (I was "just looking" about a month ago and saw the $59, now that I'm ready to purchase, no luck!!!)
Did you notice that SWA return flights are not that convenient? Non-stop is important to us with DS9 and DS4. Also, we like to leave later in the day to get one last WDW fix before coming home.
Good luck to all of you who are trying to get the $68 fare.
