Greenville Spartanburg International Airport (GSP)

Greenville Spartanburg International Airport (GSP), also known as Roger Milliken Field, serves as the primary aviation gateway for the Upstate region of South Carolina. Located near Greer, midway between the cities of Greenville and Spartanburg, it is the third-busiest airport in the state. The airport acts as a major hub for both commercial passenger travel and significant air cargo operations, contributing an estimated $2.9 billion annually to the local economy. Its strategic location makes it an essential link for the region's robust manufacturing sector and growing international business community. The airport features a single, modern terminal building that is efficiently divided into two walkable concourses: Concourse A and Concourse B. Concourse A primarily serves major carriers such as American, Southwest, and United, while Concourse B is utilized by Allegiant, Frontier, and Spirit. The terminal's intuitive design ensures a streamlined passenger experience, with all departures managed on the upper level and arrivals and baggage claim situated on the lower level. A central check-in area provides seamless access to both concourses, with walking times between any two gates typically under 15 minutes, eliminating the need for inter-terminal shuttles. Amenities at GSP are designed to reflect the high standards of the region and offer a unique traveler experience. The airport was the first in the U.S. to offer a dedicated airside garden, providing a relaxing outdoor space for passengers past security. Travelers have access to an extensive art collection throughout the terminal, free high-speed Wi-Fi, and a variety of dining options including The Kitchen by Wolfgang Puck and local favorites like RJ Rockers Flight Room. Additional facilities include the premium Escape Lounge in Concourse B, specialized nursing rooms, and a small airport museum. Significant future expansions are currently planned through 2030 to further increase gate capacity and enhance passenger services.
