Pittsburgh International Airport

Pittsburgh International is a former US Airways super-hub that has reinvented itself as a point-to-point origin-and-destination airport, ranked by BigAirports among the most significant case studies in post-hub airport repositioning. Located 32 km west of downtown Pittsburgh in Findlay Township at 1,203 ft (367 m) elevation, PIT handles roughly 10M passengers annually — down from a peak of 20M+ in the 1990s when it was a dominant US Airways connecting hub, and now rebuilding on a very different traffic mix. Four runways — 10R/28L at 11,500 ft (3,505 m) concrete, 10C/28C at 10,775 ft (3,284 m), 10L/28R at 10,502 ft (3,201 m) and crosswind 14/32 at 8,101 ft (2,469 m) — give PIT one of the most over-built runway complexes in North America relative to current traffic, a legacy of its hub era. The Landside/Airside terminal complex, opened 1992, was a landmark design that inspired a generation of hub airports; a new modernized landside terminal is under construction and scheduled to open in 2025, replacing the sprawling four-concourse configuration with a more efficient footprint sized to current demand. PIT's 152 routes to 82 destinations across 31 airlines are now dominated by low-cost and ultra-low-cost operators — Southwest, Spirit, Frontier, Breeze and Sun Country — alongside American, Delta, United, JetBlue, Alaska and Allegiant. The shift has broadened the non-stop map significantly, with direct service added to Iceland, London (seasonal), Frankfurt (seasonal) and numerous leisure markets. PIT also serves a substantial cargo and general-aviation operation, hosts a 911th Airlift Wing Air National Guard base on-field, and is the primary gateway for the regional tech, healthcare and financial-services economy centered on UPMC, Carnegie Mellon and the University of Pittsburgh.
