Mainline might be closing their domicile there, but as of yet Republic has not.

TSA also has a prorate contract for their Airways RJs, so I'd guess most if not all of the PIT Express flying remaining will be REP or TSA. Methinks we might turn PIT out of somewhere...but only like a regular outstation. Guess we'll find out mid-Oct when Airways releases the schedule (per J.W.'s post on the company board).
