Very good, and this gets you into the Admirals Club even without status. I'm pleasantly surprised, since that means PIT is selling tickets, BA does this to squeeze more people on board, not to be nice to you. There are some rebuilding works going on in PIT, but 2 hours would be fine there, one advantage of places like PIT is that it's all very quick and easy. If returning to PIT then there are some slightly odd rope barriers to feed you though to US CBP and to separate you from domestic travellers.
