Pittsburgh International Airport
Pittsburgh International Airport has five terminals. The airport uses one large passenger screening area which connects to an automated underground tram system which ferries passengers to the intersection of terminals A, B, C, and D. The original design of the air-side terminals included a large amount of retail and restaurant space. The name "Airmall" conveyed the intent to blend the airport with a shopping mall.
