How FlyerIntel works
Built on official data
21,708,321 individual flight records from the US DOT Bureau of Transportation Statistics, July 2023 – July 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.
