Greenville–Spartanburg International Airport

Before GSP, both Greenville and Spartanburg had their own airport and competed for airline service. In the 50s, industrialist Roger Milliken (CEO of Milliken & Company) worked with other business leaders to get a shared airport for both cities. A proposal was accepted in 1958, approving both the construction of the airport and the creation of a commission, which was to be headed by Milliken. On October 15th, 1962, GSP opened, becoming the primary airline destination in the region. The terminal and cargo facilities were expanded in the 80s, while the runways were lengthened twice in the 90s. In 2004, the airport was named Roger Milliken Field. Traditionally, the airport was served by legacy carriers, as there were nearby hubs in Atlanta (Delta Air Lines) and Charlotte (American Airlines). This lead to high fares. However, in 2006 Allegiant Air began to service the airport, while Southwest Airlines began service in 2011. These occurrences led to decreased rates (average fares were reported to have decreased 14% in 2012, the largest in the country) and more passengers. Furthermore, in 2012 the airport began a four-year terminal improvement program to modernize the terminal and improve passenger flow. The program cost $102 million and also played the role of preparing the airport for future expansion.

The airport is located midway between the cities of Greenville and Spartanburg.
