Well, statistics show that in the past when the jet routes decreased, turbo-props picked up the slack. It's not so much that they're looking out for "number 1," but financially it makes sense.

It sucks that US Airways and PSA are loosing routes, but I bet you a dollar to a doughnut that once the economy recovers you will start seeing US Airways/PSA flying these routes again. Just be patient...

Good luck and keep the faith...
