Check the current status and details of an airline order using IATA ONE Order's OrderView and OrderList message types

Steps

1. Confirm the airline (or NDC/ONE Order-compliant partner) you're integrating with has implemented the ONE Order standard — ONE Order is an IATA specification each airline implements individually, not a single hosted API you can call directly.
2. To find one or more orders matching search criteria (e.g., passenger name or order reference), send an OrderList request per that airline's implementation of the IATA AIDM Implementation Guide.
3. To retrieve the full current state of a specific order — pricing, conditions, time limits, order status, and passenger information — send an OrderView request referencing the order ID.
4. Watch for OrderChangeNotif messages, or the ORDSTS (Order Status Change) capability where implemented, to detect delivery or refund status changes the airline pushes rather than ones you have to poll for.
5. Map the airline-specific response back to your internal order model, since ONE Order field-level implementation varies by carrier and by which IATA implementation guide version they support.
