ONE Order is an IATA standard under Passenger Services Conference Resolution 797. ONE Order aims to modernise the order management process in the airline industry. It achieves this by overcoming the inefficiencies and unnecessary cost associated by having three separate records (the Passenger Name Record or PNR; e-ticket and EMD, a standard for electronically documenting ancillary revenue). ONE Order will replace these three existing records by providing the technical standards upon which a single customer order record can be created and utilised. As with NDC, ONE Order is not an industry portal nor a commercial service. This means that individual airlines and others can implement the standard in a number of ways so as to ensure compliance with data protection legislation.
Because ONE Order is a standard, and flexible in its application, it is possible for airlines and other ONE Order users to achieve compliance with local data protection legislation in a number of ways. IATA does not intend to prescribe one approach over another. Such a matter will be for individual ONE Order users to make independent decisions on, after taking appropriate legal advice.
