How delays work at GSP

A ground stop holds flights bound for GSP at their origin airports. A ground delay program spaces arrivals out so the airport is not overloaded. Departure and arrival delay messages describe the average wait the FAA expects. None of these tell you whether your own flight is late, so always check your airline as well.

Local tips

  • The Economy lots are the best value for a trip of several days, since the $10 daily rate is about half the garage price.
  • The Escape Lounge has a lower pre-booked price, so book in advance if you plan to use it.
  • GSP is open 24 hours a day, so late and early flights are easy to reach.
  • Download the airport's Live Shuttle Tracker to see when the economy lot shuttle arrives.
