How FlightFinder gathers its data

Name: FlightFinder route and airport reference data

Data sources

Jonty/airline-route-data (community): A weekly-updated global airport + route inventory maintained at github.com/Jonty/airline-route-data. Provides airport metadata (IATA, ICAO, lat/lon, timezone, elevation) and which carriers fly each route. Updated weekly; we mirror nightly.
FlightConnections.com (our crawl): Public route-map pages, scraped under fair-use derivative terms. Provides per-airline aircraft assignments — which aircraft type each carrier operates on each route. Updated quarterly.
FAA Releasable Aircraft Database: US public-domain dataset for aircraft tail-number → type lookups.
NTSB Aviation Accident Database: US public-domain accident records, surfaced on our safety overlay.

Cross-validation

Every route shown on FlightFinder is independently confirmed by at least one source. Routes appearing in only one source are flagged on the page with a "single-source" badge. The freshness date shown on each page reflects when its sources were last cross-validated.

What we do not do

We do not generate flight data with AI. Every numerical claim traces to a named source.
We do not show real-time availability on indexable pages — that lives behind the search UI.
We do not publish data behind paid subscriptions on these pages.
