POST /api/momondo/flights/search

Price: 20 credits

Search momondo flights between two places for a given date, trip type, cabin class and passenger mix. Returns ranked itineraries with the cheapest price and booking deeplink, per-provider booking options, full leg and segment details (airports, departure/arrival times, duration, stop count, operating airline, flight number and aircraft), and best/cheapest flags. For round trips pass a return date. Optional filters narrow the results by max stops, airlines, alliances, max price, max leg duration and included carry-on/checked bags. Origin and destination are airport or metro codes (resolve them via the places search).

How to use it

Search flights between two momondo airport/metro codes (origin, destination — resolve via places/search) for a depart_date (and optional return_date for round trips), trip_type, cabin_class, adults and sort. Optionally filter by max_stops, airlines, alliances, max_price, max_duration_hours and carry_on_bags/checked_bags. Returns ranked itineraries with id, price (cheapest), currency, is_best, is_cheapest, provider_name, booking_url, booking_option_count, provider_count, legs (origin, destination, departure_at, arrival_at, duration_minutes, stop_count, segments with airline/flight_number/aircraft/cabin/airline_logo) and options (per-provider price and booking url).

Errors

• 422 — The request body did not validate Check the fields against this schema. A URN with the wrong prefix is the most common cause.
• 408 — The request ran past its time limit Raise `timeout` in the request body, up to the maximum this endpoint documents. Lowering `count` or turning off the `with_*` flags also helps, because less work finishes sooner.
• 412 — No flights found for the given route, date and passenger combination Retrying will not help: either the entity does not exist, or the input points at a different one.
• 429 — Too many requests: a rate limit or a usage window is exhausted When the response carries an X-Retry-After header, wait that many seconds and retry: the same number is in the body as `detail.retry_after`, and the limit clears once that window passes. The message in the body names the limit that was hit.
• 500 — Something broke on our side Retrying will not help. If it keeps happening, send us the X-Request-ID from the response headers.
• 529 — Rate limit reached, or the endpoint is overloaded Wait at least 30 seconds, then retry.

Response headers

• X-Error — Error message text (present only on error)
• X-Request-ID — Unique request identifier
• X-Execution-Time — Execution time in seconds
• X-Result-Count — How many records the body carries. 0 means an empty result, which is a normal answer and not by itself an error. A non-zero count can come back together with X-Error when the failure happened partway through — read this header and X-Error independently.
• X-Total-Available-Results — How many records exist for this query, when the endpoint can say. On a `dry_run` request this is the answer and the body is empty. It saturates: the endpoint's documented maximum means 'at least that many', any smaller number is exact.
• X-Warning — Present when the request body carried keys this endpoint does not document. They were ignored, so any filter you meant to apply through them did not apply. Check the spelling against this schema and retry.
• X-Retry-After — Seconds to wait before retrying. Present only on 429.
