Endpoint
GEThttps://airports-reference.x402tookit.com/big-hubs?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to identify or rank major airports by passenger traffic volume globally or within a specific country or continent. Prefer this over a generic airport search when the use case is about hub size, traffic ranking, or identifying major aviation centers rather than finding a specific airport by code or location.
Side effects
- Invalid continent code returns an error or empty result set
- Invalid ISO country code or unrecognized country name returns no results
- Limit value outside 1–50 range may be rejected or clamped
- Wikidata source may have outdated or missing passenger figures for some airports
- Degraded flag may be set if data source is partially unavailable
