Airport Overview
Greenville-Spartanburg International Airport (KGSP/GSP) serves the Upstate South Carolina region from Greer, roughly 12 miles from downtown Greenville and 15 miles from Spartanburg. Owned and operated by the Greenville-Spartanburg Airport District, it is a commercial-service airport that handled about 59,545 aircraft operations in 2024 and a record three million passengers in 2025. For private travelers it pairs airline-grade infrastructure with a dedicated general aviation terminal.
Runway Capability
KGSP has a single runway, 4/22, at 11,001 feet by 150 feet with an asphalt/concrete surface. This accommodates the entire range of business aircraft, including ultra-long-range heavies like the Gulfstream G650 and Global 7500 and even airliner-class types, with ample margin for full-fuel, hot-day departures. Field elevation is a low 964 feet MSL, so density-altitude effects remain minimal even on warm afternoons.
FBO & Ground Services
Cerulean Aviation is the airport's sole FBO and the only full-service general aviation operator in Upstate South Carolina. It provides 24-hour line service, Jet-A and 100LL fuel, on-site U.S. Customs clearance, ground handling, and concierge support from a terminal expanded in 2025 to over 12,700 square feet, with conference rooms, a refreshment bar, and a pilot lounge with showers.
Charter Considerations
As a towered commercial field with a long runway and full FBO support, GSP imposes no aircraft-size constraints on charter. The Jet Finder sources aircraft from FAA Part 135 operators and compares positioning fees, hourly rates, and aircraft availability for your route. Because GSP is a busy commercial airport, prior arrangements through Cerulean for parking and handling are recommended during peak periods.
Customs & International Access
KGSP offers on-airport U.S. Customs and Border Protection, making it a genuine international gateway for private and corporate flights. Cerulean Aviation coordinates customs clearance for arriving international traffic, so operators can clear directly at GSP rather than diverting to another port of entry. Advance notice to CBP and the FBO is standard practice for international arrivals.
Safety & Planning
GSP is fully towered with ILS, RNAV (GPS), and VOR approaches supporting all-weather operations. Part 135 charter flights operate IFR for ATC separation and structured routing. A significant 2026 planning note: the airport has scheduled runway rehabilitation that includes temporary full closures during specific windows, so review NOTAMs and confirm operating status with the FBO when scheduling around those dates.
Seasonal & Regional Factors
The Upstate's humid subtropical climate brings warm summers with afternoon convective thunderstorms that typically build between early and late afternoon; morning departures generally offer the smoothest conditions. Winter brings occasional de-icing needs but is otherwise mild. Regionally, GSP anchors a manufacturing-heavy corridor (BMW, automotive and aerospace suppliers) that drives steady corporate and charter demand.
