Travel Technology Specification
What is ONE Order?
IATA ONE Order Standard
Definition: An IATA initiative designed to modernize airline retailing by replacing the legacy triumvirate of PNRs, E-Tickets (ETKTs), and Electronic Miscellaneous Documents (EMDs) with a single, unified retail order record.
Simple Explanation
Just like when you order on Amazon and get one single order ID containing your laptop, warranty, and case, ONE Order gives an airline traveler one single Order ID for their flight, extra baggage, lounge access, and meals.
Technical & Protocol Spec
ONE Order converges financial accounting, booking fulfillment, and delivery into a single data record. It eliminates complex ticketing reconciliation between BSP/ARC and simplifies disruption management, re-routing, and refunds.
Production Example in Flight Operations
A passenger modifying their flight and seat selection under a single Order ID without needing ticket exchanges, fare recalculations, or reissue of separate EMD coupons.
Key Technical Takeaways
- Eliminates separate PNRs, e-tickets, and EMD documents
- Treats travel purchases like modern e-commerce cart orders
- Dramatically simplifies airline accounting and passenger changes
