This airport a) thinks its on par w/ NYC and b) is no where near Pittsburgh.
To get to any kind of short term parking you have to drive halfway around the airport. But you dont know that until you get inside because all the Short term parking signs have signs over them saying "closed". Once you get inside from long term parking, youll walk almost a full mile to the security and ticketing part of the airport. After security, youll take a NYC type shuttle to the actual terminal. Why these 2 buildings need to be separate, I have no idea. its asinine.
Ok, now that Ive gotten that out, the good points. On the ticketing level, the electronic boarding pass machines are before the lines, so you dont need to wait in line to use them. There are also machines all over the security level that will let you print your boarding passes for 6 selected airlines. The security line moves so amazingly quickly, it was very impressive. Once you get to the second building, all the terminals are clearly marked.
Oh, and did I mention that Pittsburgh International is no where near Pittsburgh. Cuz its no where near Pittsburgh.
