Greenville Spartanburg International Airport

Greenville-Spartanburg International Airport (KGSP) sits 12 miles east of Greenville and 15 miles southwest of Spartanburg, South Carolina. The field handles modest commercial service (American, Delta, United, Allegiant, Frontier, JetBlue, Southwest) and a meaningful flow of business aviation, particularly driven by the substantial BMW manufacturing plant (BMW Group's largest US facility is on the airport), the Michelin North America corporate footprint, the Spartanburg corporate community, and the Upstate South Carolina German / European corporate flow.

The two runways at KGSP (4/22 11,000 ft, 14/32 7,602 ft) handle every current business jet without restriction. Two FBOs (Stevens Aerospace and Cerulean Aviation) handle business movements. Field elevation is 964 feet, no density-altitude concerns. The dominant operational considerations are summer Southeast thunderstorms, occasional winter ice events, and the structural Upstate weather pattern. The BMW plant generates substantial year-round corporate-aviation traffic from BMW HQ in Munich and other European executive flows; the field also sees meaningful Clemson football game-day pressure (Clemson University is 45 minutes west). Ground time to downtown Greenville is 25–30 minutes; the BMW plant is 5–10; downtown Spartanburg is 15–20.

Greenville–Spartanburg International Airport – also known as Roger Milliken Field – is near Greer, South Carolina, United States, midway between Greenville and Spartanburg, the major cities of the Upstate region of South Carolina. The airport is the third-busiest airport in South Carolina, after Charleston International Airport, and Myrtle Beach International Airport with over 3.04 million passengers in 2025, the most in its history.
