US Airways Group announced that they were going to increase the airfare for flights from Philadelphia to Pittsburgh. The increase is the fare is set to begin in early January.

At that time, US Airways will be the only airline offering flights between Philadelphia and Pittsburgh. This will increase the price of the fare by $580 which includes tax.

Senator Bob Casey, a Democrat from Philadelphia, asked US Airways not to increase the fare for flights between these two cities because of the weak economy. He warned the airline that the increase in the fare would greatly hurt people who frequently use that route for business purposes.

Todd Lehmacher who is a spokesman for US Airways said that the price increase will likely stay in place. Lehmacher also said he was willing to talk with the senator about the increase in the fare.

At this time, there is no word on when talks will take place.
