Travel and Airline Distribution
Coverage market (aggregators publish the airlines they reach) with an ndc standards spine. The Kin Score Market layer reads each provider in its market: who it integrates with, how deep those integrations go, and where the market publishes its own structure. Methodology.
Where this market publishes its structure
- Duffel supported airlines (IATA code, direct NDC vs GDS source, feature status) machine-readable
- IATA NDC certification register not machine-readable: IATA portal login; certification pages 404
- OpenTravel Alliance members not machine-readable: 403
- Amadeus, Sabre, Travelport NDC content lists not machine-readable: marketing pages or keyed
- Kiwi.com carriers not machine-readable: none public; not in the catalog
- Hotelbeds, Expedia Rapid, Booking.com supplier coverage not machine-readable: keyed or 404
- Airbnb software partners not machine-readable: names only
Own = declares at least one integration itself; covered = visible only because an aggregator, standards body, regulator or partner contract names it; distribution-only = listed only on cloud marketplaces it sells through, a channel reported beside, never counted as its own declared integrations; undeclared = nothing we can read, so no number; declares_compatibility = providers with a `compatible` shape vote, report only (kin, 2026-10-13): never counted as own, never in depth or position.
