PIT is overwhelmingly dominated by USAirways, the hub carrier. In addition to regular USAirways flights, Piedmont Airlines and PSA run USAirways Express services previously known as "Allegheny Commuter" routes.
Vanguard Airlines is the other airline based at PIT.
All of the other major U.S. airlines, except Alaska, provide limited service to/from PIT.

Small correction - Vanguard is based in Kansas City, but does operate from PIT to ATL, amongst others. It is also one of the few places to see Pan Am 727s in their reincarnated form (operating to Pease and Sanford). Otherwise over 80% of the traffic is US.

US Airways is the dominant carrier at PIT. It operates 504 daily flights and is the airline's biggest hub. The airport is wonderful. It's clean, efficient, has a nice mall, and is new. The midfield X terminal opened in 1992, replacing the old and decrepit Greater Pittsburgh International Airport terminal. The terminal is spotless, clearly marked, and a very pleasant transit point. When I do fly US Airways (in the past and this year, after a five year hiatus, I always try to book connections through PIT if possible and logical).
United, TWA, AA, NW, Continental, Delta, the newest incarnation of Pan Am, and other airlines operate from PIT, but it is overwhelmingly US Airways/Express territory.
