You will find Greenville–Spartanburg International Airport (Roger Milliken Field) near Greer, South Carolina, situated conveniently between Greenville and Spartanburg. Spanning 3,500 acres primarily in Spartanburg County, this small-hub primary facility stands as the third-busiest airport in South Carolina. It set a historical record by serving over 3.04 million passengers in 2025, operating with a single 11,001-foot runway.
Navigating the airport is straightforward, as all departing travellers use a single main terminal building with a shared check-in level. From the central facility, you can access two distinct concourses for your flights. Concourse A serves the majority of the airport's passenger air carriers, while Concourse B handles the remaining domestic flight departures.

Lost, delayed or damaged baggage at GSP
If your checked bag doesn't turn up on the belt, act before you leave the baggage-claim area — that's where every airline keeps its Baggage Service Office.
- Go to your airline's Baggage Service Office in the baggage-claim hall of your arrival terminal.
- File a Property Irregularity Report (PIR) and get your file reference (WorldTracer) number. Keep your bag-tag receipt and boarding pass.
- Track it online using that reference on your airline's baggage-tracking page — most bags are located within 24–48 hours.
- Claim your essentials. On delayed bags airlines reimburse reasonable interim purchases (toiletries, clothing) — keep receipts. International trips are covered by the Montreal Convention.
- If it's truly lost (generally after 21 days) or damaged, file the claim at the same office — damage must be reported before you leave the airport.
Left something in the terminal (not a checked bag)? That's handled by the airport Lost & Found. Items left at a TSA security checkpoint are held by the TSA, not the airline.
