A practitioner’s hub for modern airline retailing, turning complex industry architecture into clear tools, visual stories and practical insight.
From Fragmented Records to Unified Orders
One passenger journey can create PNRs, tickets, EMDs, SSRs, payment records, coupons, queues and external references across multiple systems. Explore how modern Offer and Order architecture replaces fragmented records with a more coherent retailing model.
ONE Order provides a unified order model; transition architectures may still retain legacy records and integrations while capabilities migrate.
Illustrative, not an exact industry count. Actual documents and messages vary by airline, itinerary, interline arrangement, servicing flow and architecture. The visual explains how complexity can increase across legacy systems.
In traditional Passenger Service System architecture, a PNR, Electronic Ticket, flight coupons and Electronic Miscellaneous Documents can each carry a different part of the customer journey. IATA ONE Order and modern Order Management aim to simplify that landscape by managing accepted Offers, products and services through a unified retailing record.
Each path connects existing articles, references and working tools. Counts are calculated from the current content inventory; smaller paths are labelled as growing collections.
