Well... Since USAirways is drastically reducing the number of flights in and out of PIT, reducing it from a hub to a "focus city" or whatever they're calling it now, it seems obvious that they are going to be cutting quite a bit... And not just flights by contract carriers, but mainline and WO's, too.
What is the number I read... Down from 100+ flights per day to 40 or something? That's a pretty big cut, esp. since the 100+ is already a cut from what it was two years ago... Or five years ago, for that matter.
Then again my numbers aren't necessarily right, it's just what I remember. And why are you specifically concerned about TSA's -41's?
