Where the numbers come from
- Wait times
- Guam publishes no wait time waittimes.io can read yet.
- Usual busyness
- TSA's own hourly passenger counts per checkpoint, published weekly in its FOIA reading room. This page uses 131 days of counts, 22 March to 5 September 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.
