If US Airways is considering replacing some cities like Toledo with just Beeches to PIT, they might as well just pull the plug on the whole thing. Since mainline pulled out in 2001 - the market has gone completely down hill. They were doing okay when they went from 2 F-100s and 2 D328s to 4 ERJs and 2 328s, and managed okay when they went to 5 DH8s and 1 ERJ...but when they went all prop (read: all Shuttle)...the market just completely fell apart. Their unreliable nature drove most of the passengers to Delta or ATA. During the time period when they had just the one jet...it had the highest load factor of any other flight, including ones in the morning or during other peak times. People here wanted jets...when US took them away, the passengers went as well.
US went from the largest airline here to one of the smallest...seems to be a typical experience. Delta is king now and the airport is working with them to start service to New York and Dallas. They have also started talking with Indy Air and JetBlue...only a matter of time I guess.
