How this service works
Convert an airline radio callsign (SPEEDBIRD) to its airline, or an airline code or name to its callsign.
Output
Returns an array of matching airline records, each containing IATA code, ICAO code, airline name, radio telephony callsign, country, active status, OpenFlights ID, and route count from the OpenFlights snapshot. Also includes a summary, verdict, attribution, and snapshot date.
Example use cases
Identify airline from ATC callsign
“I heard the callsign SHAMROCK on an air traffic control feed — which airline is that, and is it still active?”
Look up callsign for airline booking
“What is the radio telephony callsign for Lufthansa? I know its ICAO code is DLH.”
Resolve IATA code to full airline info
“Can you tell me the full name, country, and radio callsign for the airline with IATA code QF?”
Technical details
Endpoint
GEThttps://airlines-reference.x402tookit.com/airline-callsign?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve an aviation radio telephony callsign to an airline identity, or reverse-lookup a callsign from an IATA code, ICAO code, or airline name. Prefer it over general aviation databases when you specifically need the callsign↔airline mapping with codes and country in one call.
Side effects
- No match found if callsign or code is unrecognised or misspelled
- Ambiguous results if multiple airlines share a similar name or code
- Data may be stale as it is based on a 2017 OpenFlights snapshot
- Missing fields (null) for airlines with incomplete OpenFlights records
- Query parameter validation error if neither airline nor callsign is provided
