Error Responses

The server returns structured errors with suggestions:

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.
