Does PWM publish a live TSA wait time?
Not one waittimes.io reads, so this page carries no number for right now and never predicts one. The national page ranks the 23 airports whose live number waittimes.io reads.
Does PreCheck have a shorter line at PWM?
This page has no lane-by-lane wait time for PWM, 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 Portland Maine on waittimes.io.
- Usual busyness
- TSA's own hourly passenger counts per checkpoint, published weekly in its FOIA reading room. This page uses 175 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.
