Greenville-Spartanburg International Airport just had its busiest day in its history, screening 6,732 passengers in a single 24-hour stretch on Oct. 25, 2026. Airport officials say the figure marks the highest number of travelers GSP has ever served and screened in one day.
According to WYFF, the Greer-based airport celebrated the milestone. A GSP Facebook post cited in the station's report credited the achievement to travelers, airline partners, and the surrounding community, and thanked passengers for choosing GSP and for enabling connections to their preferred destinations.
A Pattern of Record-Breaking Months
The single-day total follows a string of passenger milestones at the Upstate airport. Earlier this year, GSP recorded almost 300,500 passengers in June and nearly 293,800 in May, setting back-to-back monthly records, per the same WYFF report. Those totals topped the airport's previous monthly record of about 290,000, which had been set in October 2025, the station notes.
Growth at GSP isn't new. Passenger traffic through Nov. 25, 2024, was up 12.8% compared with the same period in 2023, according to WSPA. That station reported that exactly 2,612,236 passengers had passed through the airport as of Nov. 25, 2024, surpassing the previous high-water mark set in 2019 — though a separate WYFF article from that period described the total differently, saying the airport had welcomed over 2,612,236 passengers by that date. The two outlets differ on whether the figure was an exact count or a floor, and neither account has been reconciled here.
Expansion Plans Driving the Numbers
The airport's growth trajectory has been well documented heading into this year. GSP served more than 3 million passengers in 2025. The airport projected about 5% overall growth for the year, per the Post and Courier. The airport also expected airline seat capacity to increase by roughly 10 to 15% in the fall, the outlet reported.
The airport also added new flights and expanded frequencies, scbiz.com reported.
Located in Greer, South Carolina, GSP continues to position itself as a growing regional hub for the Upstate, with officials pointing to the single-day record as the latest marker of that momentum.
