Data sources, refresh cadence and validation methodology.
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.
When the same accident or incident is reported by more than one investigation authority, FlightFinder collapses those reports into a single occurrence record. Matching is keyed primarily on the aircraft registration and event date, falling back to event location and date, or to a per-source identifier when neither registration nor location is available. Where sources disagree, the record from the source ranked highest in our internal priority list is kept — national investigation authorities together with the U.S. NTSB and Australian ATSB rank highest, secondary aggregators such as Wikidata rank lowest — and any field the top-ranked record leaves blank is filled in from the other matching reports; every contributing source is still recorded and linked. Datasets outside this occurrence corpus — ASRS, the FAA wildlife/laser/runway-incursion datasets, and EASA directives/bulletins — are not deduplicated against it, as they describe different report types.
The turbulence route checker lists the airlines observed on a route and, for each, what our accident and incident records hold: how many occurrences are attributed to that carrier, how many were fatal, how many were hull losses, when the most recent fatal accident was, and the size and average age of the fleet we track.
These are counts, not a rating. We publish no safety score and no letter grade for airlines. An earlier version of this page described one; it was removed before launch because the data cannot support it. Our occurrence corpus attributes only a minority of records to a specific operator, and that gap is not evenly spread between carriers — so any formula over these counts would rank how well documented an airline is as much as how safely it flies, and would do so about named companies in a context where readers act on what they read.
Read the figures as a floor rather than a complete history: events we never matched to a carrier are missing from them, so a low count can mean a good record or a thin one, and the two are not distinguishable from the numbers alone. A zero is never presented as a clean record. Every airline shown meets the same regulatory safety requirements, which is the assurance that does not depend on our matching rate.
