Security and parking, live
Checkpoint waits and garage space published by the airports themselves, read directly from their own feeds.
Each airport publishes its own figures; FlyerIntel reads them unchanged and shows how old each one is. Coverage is limited to airports whose terms and robots rules permit collection. Data sources and coverage
Current disruptions
3 of the 64 covered airports are reporting conditions above normal right now.

How FlyerIntel works
Built on official data
22,316,707 individual flight records from the US DOT Bureau of Transportation Statistics, July 2023 – August 2026, covering 64 airports and 15 scored carriers, plus aviation weather from NOAA and airspace status from the FAA wherever its feed is reachable.
Every figure is reproducible
Reliability scores publish their components and weights. Sample-size thresholds are stated. Nothing is shown below the threshold that makes it meaningful.
Nothing is invented
Where a live source is unavailable, FlyerIntel says so rather than estimating. Every live value shows how old it actually is.
