Booking Find Flight Cities and Airports API

Find flight city and airport suggestions with a text query. The verified London response contained status=true, message=Success, and a data array with type, name, code, country, and countryName. Airport rows also carried city/cityName, parent, distanceToCity, and other geographic context. Results included CITY LON and AIRPORT LHR, LGW, and STN, alongside similarly named places in other countries. Select by type and geography; flight-search documentation calls for AIRPORT codes. Successful suggestion lookup does not validate downstream flight prices or searches.

Frequently asked questions

Can I use CITY LON wherever an airport code is requested?

Do not assume that. The flight-search documentation calls for codes from AIRPORT-type suggestions. CITY LON and AIRPORT LHR represent different selections.

Did a successful London lookup validate live flight pricing?

No. Only the suggestion response was verified. Flight-search, minimum-price, and flight-detail responses were not live-validated.
