Greenville-Spartanburg International Airport's history
Greenville-Spartanburg International Airport (GSP) is located near Greer, South Carolina, United States, midway between Greenville and Spartanburg—the major cities of the Upstate region of South Carolina. Before the construction of GSP, the two cities had separate airports and competed for airline service. In the mid-1950s, Roger Milliken, a textile heir, industrialist, and businessman, led a group of Upstate business leaders in an effort to build a shared airport for the two cities. They settled on a site in Flatwood, a local community with long stretches of flat land between Greenville and Spartanburg, ideal for an airport.
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. Construction began in 1961, and GSP opened on October 15, 1962, with the arrival of Eastern Airlines flight 580 at 7:33 a.m. GSP was the first modern airport built from scratch and offered several technological advancements, including being the first airport to install lights in the pavement of its runway. The airport replaced Greenville Downtown Airport as the primary airline destination in the region.
In the following decades, GSP underwent several expansions and improvements. In the 1980s, the airport expanded its terminal and cargo facilities, and in the 1990s, the runway was lengthened twice. In 2004, the airfield was named for Milliken. The arrival of low-cost carriers in recent years has helped reduce fares and increase passenger figures. In 2011, GSP received an ANNIE Award from Airline and Airport News & Analysis for being the fastest-growing small airport in the United States.
In 2012, the airport embarked on a four-year, $102 million terminal improvement program to modernize the terminal and improve passenger flow, as well as prepare for future expansion. The airport has one terminal building with two concourses: Concourse A (gates A1–A9) and Concourse B (gates B1–B4). GSP offers nonstop service to over 20 destinations and connections to hundreds of destinations worldwide. The airport covers 3,500 acres and has one runway, with plans for future expansion, including the possibility of adding a second runway.
