Fellow Pittsburgher here. Based on past experience with holiday fares, I wouldn’t be surprised to see them released later. One time I went to Disney the Sunday after Thanksgiving, the flight down was $400. I really wanted that morning flight and bought it. About a month before, it dropped to $200. I got the credit and used it for a future flight.
One concern I have right now is they seem to be dropping frequency. I am flying down the Saturday after Thanksgiving, frequency was good, I got a flight for about 20,000 points. Coming back on 12/4, non-stops are around 7:00am and 6:30pm. I was hoping for around noon. Connections aren’t even good. I’m going out to DL in early September, schedules were bad. I’m flying American out. Coming back I have SW connection I am happy with but am scared they will cancel or change times.
