Result Validity

Search results and booking links are valid for approximately 15 minutes. Flight prices are determined through a real-time bidding process and are not guaranteed beyond this window. For stale results, run a new search.

Error Responses

• airport_not_found -- airport could not be resolved. Try an IATA code, city name, or airport name.
• disambiguation_needed -- multiple airports found (e.g. "New York" returns JFK, LGA). Pick one and retry.
• invalid_date -- date format not recognized. Use YYYY-MM-DD, DD.MM.YYYY, or similar.
• no_results -- no flights available for the given criteria. Try different dates or a nearby airport.
