The airport's expansion of parking, enhanced streetscaping, and addition of new nonstop routes and more frequent flights have helped accommodate this rising demand for air travel.

The record-breaking passenger numbers at GSP were driven by the addition of new nonstop routes to Fort Myers, Pittsburgh, and Sarasota, as well as increased flight frequencies to destinations like Providence, Tampa, Hartford, New York, and Chicago. The airport has also extended its seasonal schedule to Los Angeles.
