Trip.com Flight Search API Documentation Search flights between two airports or cities, one-way or round trip. Each itinerary has the price with taxes and currency, the cabin, seats left, stops, total duration in minutes, carriers and the segments with flight number, airline, aircraft, airports, terminals and local times in ISO 8601. Itineraries are sorted by price, up to 50. Add return_date for a round trip: the answer lists the outbound options (leg: outbound) and the price of each is the price of the whole round trip. Every round-trip option has a policy_id. Send it again with the same search to get the return legs of that option (leg: return). Cost: 1 credit for a one-way search. 3 credits for each successful round-trip call. Failed calls cost 0.
