Construct and price a multi-city open-jaw itinerary with Amadeus Flight Offers

Steps

1. Use the Amadeus flight offers search API in multi-city mode by setting the originDestinations array with more than two elements; specify independent originLocationCode and destinationLocationCode for each leg.
2. For an open-jaw itinerary (fly into city A, depart from city B), set the first leg's departure to the origin and arrival to city A, and the return leg's departure to city B and arrival to the final destination.
3. Include separate departure date windows for each leg; Amadeus supports a single fixed date per leg in multi-city mode rather than a date range.
4. Parse the itineraries array in the response — each offer will contain one itinerary per leg; compute and display the combined price and segment details.
5. Price the selected multi-city offer using the flight offers price endpoint to confirm availability and obtain a final bookable price before proceeding to order creation.
6. When creating the order, submit all itineraries and passengers in a single POST to avoid partial booking scenarios.
