Western Pennsylvania gateway, former US Airways mega-hub
Pittsburgh International sits about 27 km west of downtown Pittsburgh and was once a major US Airways hub. Today it operates as a focus city for several carriers without a single dominant operator. American, Delta, United, Southwest and JetBlue all run substantial schedules, and Spirit and Frontier add LCC competition. International service includes London via British Airways and seasonal European routes.
Major carriers: American, Delta, United, Southwest, JetBlue. Low-cost carriers: Southwest, Spirit, Frontier, Breeze Airways.
