Wonder why Pittsburgh is getting such infrequent service? When I went to Orlando a couple weeks ago, there were only 3 non-stops on a Saturday, 9:25AM, 11:45AM, and 1:05PM. We ended up on a 5:50PM flight thru Charlotte. I really missed the 8:45PM Pittsburgh non-stop (as well as the old 5:55PM non-stop, flight 781).
