Greenville–Spartanburg International Airport (IATA: GSP, ICAO: KGSP, FAA LID: GSP) – 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.[3]

The Federal Aviation Administration (FAA) National Plan of Integrated Airport Systems for 2017–2021 categorized it as a small-hub primary commercial service facility.[4]

History

Before construction of the Greenville–Spartanburg International Airport (GSP), each city had its own airport and competed for airline service. In the mid-1950s Roger Milliken, a textile heir, industrialist, businessman (CEO of Milliken & Company), worked with other Upstate business leaders to get a shared airport for the two cities. In 1958 a proposal for an airport between the two cities was presented to the legislative delegation for the two counties, which approved the construction and the creation of an airport commission, headed by Milliken.

GSP opened on October 15, 1962, replacing Greenville Downtown Airport as the primary airline destination in the region. Delta Air Lines, Eastern Air Lines, and Southern Airways had all been serving both Greenville and Spartanburg separately however only Eastern and Southern moved to the new GSP airport while Delta discontinued their service. In the 1980s, GSP expanded its terminal and cargo facilities, and the runway was lengthened twice in the 1990s. In 2004, the airfield was named for Milliken.

Having been served by legacy carriers, with large hubs in nearby Atlanta and Charlotte, GSP had long been plagued with high fares. The arrival of low-cost carriers in recent years has reduced fares and increased passenger figures. Allegiant Air began flights to Florida in 2006,[5] and in 2011 Southwest Airlines began service to five cities.[6]

Local officials attribute Southwest's presence to an unprecedented 38% growth in passenger figures between 2010 and 2011.[7] In 2011 GSP received an ANNIE Award from Airline and Airport News & Analysis for being the fastest-growing small airport in the United States.[7] In 2012 the U.S. Department of Transportation's Bureau of Travel Statistics reported that average fares from GSP decreased by 14%; the largest decrease in the country.

Facilities

The airport covers 3,500 acres (1,400 ha) and has one runway, 4/22, 11,001 ft × 150 ft (3,353 m × 46 m) asphalt/concrete.[1][8]

The airport is mostly in Spartanburg County with a portion in Greenville County. It is in an unincorporated area, adjacent to sections of Greer.[9][10]

The airport has one terminal building with two concourses: Concourse A (gates A1–A9), and Concourse B (gates B1–B4). The check-in level is the same for all passengers. In 2012 the airport embarked on a four-year, $102 million terminal improvement program which would modernize the terminal and improve passenger flow, as well as prepare for future expansion.[11] Future planning includes several options, i.e., the expansion of the terminal by 300% of its current capacity and the possibility of the addition of second runway, parallel to the existing one.

Concourse A is used by American, Southwest, Silver Airways, Avelo Airlines and United. Allegiant Air and Delta use Concourse B.

The airport can handle up to 250 passengers per hour through immigration and customs checkpoints.[12]

FedEx has a major package facility on the north end of the airport, and BMW has a facility which supports easy transfer of arriving parts to the company's manufacturing facility, three miles to the east.

In July 2016, GSP airport and Senator International of Germany announced that a regularly scheduled twice-weekly cargo service would start in November 2016 between GSP airport and Munich, Germany. The cargo service would be the first scheduled international route for the airport.[13][14][15][16] Senator International started the international cargo service to Germany in November 2016, operated by Air Atlanta Icelandic with a Boeing 747-400F aircraft, to both Munich and Frankfurt–Hahn Airport.[17][18]
