Airlines API

4,650 airlines past and present with IATA and ICAO codes, callsigns, alliances and hub airports

Every airline with a story, in one reference layer: 4,650 carriers past and present from Wikidata (CC0), 2,669 with IATA codes — the crosswalk travel tech actually needs. Resolve DL to Delta Air Lines with its ICAO code DAL, callsign DELTA, SkyTeam membership and real hub list (JFK, LAX, Sea-Tac...); resolve ICAO BAW to British Airways and Oneworld. Historic codes resolve too, active carriers ranked first — and defunct airlines carry their end year (Pan Am: 1991), which matters because IATA codes get reused. Search by name, country or alliance: Star Alliance lists its 68 active members led by Lufthansa, Turkish and United; Japan returns JAL and ANA on top. Each airline carries founding year, website, Wikipedia link and a notability rank. Completes our aviation family — pair with Airports (86k fields), Aircraft (ICAO types) and Aircraft Registrations (316k tail numbers) for full-stack aviation products. Built for booking and itinerary tools, flight trackers, loyalty apps and travel analytics. CC0 source data, self-hosted — no third-party calls at request time.

Every call needs an X-Api-Key header. A free key includes 500 tokens a month, no card required. 1 token per call, so the free plan covers about 500 calls a month.

Use cases for Airlines API

  • Resolve a flight number's airline code to its name, ICAO code and callsign in travel or tracking apps.

  • Show alliance membership and hub airports when displaying a carrier.

  • Disambiguate reused IATA codes using the defunct year, so DL means Delta today and not a carrier that folded.

  • Autocomplete airline names and codes in booking or expense forms.
