I have a friend who works for an airline that just called me and told me he can get me a steal of an airfare to PIT this weekend, which would put me about 2000 miles closer to elite status. I've heard there's a lot of shopping at PIT, but is it inside or outside of the secured area? I want to just make it a day trip so I don't have to pay for a hotel, but will there be enough for me to do for 5 hours in PIT?
