How current is this number?
Delta Air Lines publishes the DTW wait times at news.delta.com and waittimes.io reads them every 10 minutes. The time on the sign is the last read, in Eastern time. A number older than 30 minutes says so, and a feed silent for 2 hours shows when it last published instead of a number. Nothing here is predicted.

Each row of the map above is one checkpoint scaled to its own peak, so its green hours are the ones to aim for. Counts say when a checkpoint is loaded, not how long the line is.

Where the numbers come from
- Wait times
- Published by Delta Air Lines at news.delta.com. We read the page every 10 minutes and show the time of the last read. A reading older than 30 minutes is marked as such.
- Usual busyness
- TSA's own hourly passenger counts per checkpoint, published weekly in its FOIA reading room. This page uses 133 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.
