In the airline and travel industries, a passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that consists of the personal information for a passenger and also contains the itinerary for the passenger, or a group of passengers travelling together.
 The concept of a PNR was first introduced by airlines that needed to exchange reservation information in case passengers required flights of multiple airlines to reach their destination (“interlining”).
 For this purpose, IATA and ATA defined standards for interline messaging of PNR and other data through the "ATA/IATA Reservations Interline Message Procedures - Passenger" (AIRIMP).
 There is no general industry standard for the layout and content of a PNR.
 In practice, each CRS or hosting system has its own proprietary standards, although common industry needs, including the need to map PNR data easily to AIRIMP messages, has resulted in many general similarities in data content and format between all of the major systems.
