ONE Order (IATA Standard)

ONE Order is an IATA industry standard that replaces the combination of a PNR, an e-ticket, and an EMD (Electronic Miscellaneous Document) with a single, unified Order record. It is the final piece of the NDC transformation moving the airline industry from a fragmented, decades old booking record structure to one clean, retailing ready Order.

Under the current system, a traveller's booking exists across three separate records maintained by different systems. ONE Order collapses all of this into a single order owned by the airline covering flights, seats, meals, bags and any other service in one record.

• Current: PNR (GDS-held) + E-Ticket (airline system) + EMD for ancillaries

• ONE Order: Single record owned by the airline covering everything

• Already live with Lufthansa Group, Air New Zealand, and others

• Amadeus NDC Adapter supports ONE Order-based fulfillment alongside GDS content

• Travel platforms relying entirely on GDS PNR logic will face integration gaps

ONE Order is already live with select airlines. As more carriers adopt it alongside NDC, travel platforms that still rely entirely on GDS PNR logic will face integration gaps especially around ancillary retailing, post-booking modifications and financial settlement.
