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.
25providers measured
8 (32.0%)declare their own
12 (48.0%)covered by others only
1 (4.0%)distribution only (sell through, not integrations)
4 (16.0%)undeclared
2declare compatibility (report only, not weighted)
0in-market workflows shown
Provisional. Provisional and unweighted: the Market layer is not part of the composite or agent readiness. Leader lists are read within a position, never as one ranking. A provider that declares nothing we can
read is shown as undeclared, with no number: we never infer integrations.

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.
Taxonomy how this market maps onto apis.io
Derived 2026-10-23 from the 25 providers in this market we could resolve in the
catalog. The percentage is the share of those providers carrying each one; it describes the market, not the tag or industry. Tag groups have no page of their own yet, so they are listed unlinked.

Provisional: grouped by position, depth compared within a position only. Distribution (cloud marketplaces) and iPaaS bridges are counted beside
position, never inside it. Unknown-builder listings are left out of position shares and counted here.
