Airport Overview & History
Allegheny County Airport (KAGC) opened in 1931 and was, for a time, one of the busiest airports in the United States before Pittsburgh's commercial traffic shifted to what is now Pittsburgh International. Today it serves as the FAA-designated reliever airport for Pittsburgh International and the principal business-aviation field for the metro area, sitting in West Mifflin roughly 9 miles southeast of downtown Pittsburgh. It is the fifth-busiest airport in Pennsylvania and is owned and operated by the Allegheny County Airport Authority.
Runway Capability
The airport's primary Runway 10/28 is 6,501 feet of asphalt, with the crosswind Runway 13/31 at 3,817 feet. That capacity handles light and midsize jets routinely and most super-midsize aircraft with standard performance planning. Larger heavy and ultra-long-range jets can use the field but require careful runway-performance analysis for weight, temperature and conditions. The control tower, ILS, RNAV and VOR approaches support reliable IFR operations year-round.
FBO & Ground Services
KAGC is genuinely well-served for business aviation, with three full-service FBOs: Atlantic Aviation, Vantage Aviation (the former Corporate Air operation, offering 110,000 sq ft of hangar space and a ramp built for ultra-long-range jets), and Lynx FBO Network (the former Voyager Jet Center facility, with hangar space sized for a Gulfstream G650). All provide Jet-A, ground handling, hangar and terminal services. Pre-arrival coordination is recommended for hangar space and overnight parking.
Charter Considerations
With three established FBOs and steady business-jet traffic, KAGC typically has aircraft positioned nearby, which can reduce repositioning costs on charter quotes. The Jet Finder sources Part 135 operators serving the Pittsburgh area and compares hourly rates, positioning fees and aircraft quality to match the right aircraft to your mission. The field's location southeast of the city makes it convenient for travelers in the South Hills and eastern suburbs.
Safety & Planning
Charter flights operate IFR under Part 135 for ATC separation and structured routing, even in clear weather. KAGC's 1,252-foot elevation keeps density-altitude effects manageable. Appalachian terrain around the region can generate turbulence and channel weather systems, so winter frontal passages and summer afternoon convection are the main planning factors. The control tower and instrument approaches support dependable scheduling in marginal conditions.
Seasonal & Operational Factors
Winter operations may require de-icing, which can add 15 to 30 minutes to departures and carry pass-through costs of roughly $500 to $3,000 depending on aircraft size. Morning departures often avoid the worst winter icing and summer thunderstorms, which peak in late afternoon. The two-runway layout provides crosswind flexibility when winds exceed limits on the primary runway.
International Arrivals & Customs
Allegheny County Airport is not a standard 24/7 airport of entry, but customs clearance can be arranged for international arrivals through U.S. Customs and Border Protection at the Pittsburgh port with advance notice. Operators should coordinate CBP requirements and any landing permits well before an international flight. The Jet Finder can assist with international flight planning and customs coordination for trips to or from KAGC.
Regional Context
KAGC anchors private aviation for the Pittsburgh region, with Pittsburgh International (KPIT) about 16 nautical miles away for travelers needing longer runways or scheduled-airline connections. Smaller fields such as Rostraver (KFWQ) and Finleyville Airpark (KG05) sit nearby for light general aviation, but KAGC's runway length, full FBO services and approaches make it the practical choice for business jets in the metro area.
