System status

Source health, without guesswork.

TravelTSA pulls checkpoint data from each airport's own published source. This page separates freshness, source availability, and scrape reliability so you can tell whether the live board is current, cached, source-backed, or waiting on a healthier refresh.

Health combines scrape errors, checkpoint coverage, and airport timestamp age. Freshness labels describe how old the source-backed data is, not a guarantee that airport conditions have stayed unchanged.
