did say something about a MKE
-like focus city. There was an article on msnbc.com about it, but the article has expired (I think MSNBC removes articles after a certain time).
Even with 229 daily flights, US has enough of a presence that will disinterest other carriers from setting up a considerable operation (like a large Southwest operation or an increased AirTran presence). The market just isn't large to enough to interest other carriers at this point.
However, if US scales back even more (which is rumored), or when the inevitable happens (US goes out of business), carriers will begin to increase their operations.
On another note, though many complain about PIT
's lack of O&D traffic, the local traffic is actually increasing at a steady rate. It's increasing enough that the airport is running out of parking spaces, and the airport authority had to (or will - I'm not sure if it's been done yet) designate one of the employee lots as a passenger parking lot.
