Does PreCheck have a shorter line at GSP?
This page has no lane-by-lane wait time for GSP, so there is no PreCheck number to compare. TSA's counts are per checkpoint and do not separate PreCheck from standard lanes; the map above shows when each checkpoint is loaded, whichever lane you join.

Where the numbers come from
- Wait times
- There is none for Greenville Spartanburg on waittimes.io.
- Usual busyness
- TSA's own hourly passenger counts per checkpoint, published weekly in its FOIA reading room. This page uses 171 days of counts, 22 March to 24 October 2026. Public domain.
- Who reads them
- Arcane Digital, which runs waittimes.io, reads every feed every 10 minutes with its own collector and stores the time of each read. The day's reads are checked every night for a feed that has stopped or thinned, and one person reads that report the next morning. Nobody types a number in.
- What we never do
- Predict a wait in minutes, or show an old number as if it were current.
- Every feed
- How each one is read, the TSA counts and who to write to: the sources page.
