what is pnr

A Passenger Name Record (PNR) is a digital record in the database of a computer reservation system (CRS) that contains the itinerary for a passenger or a group of passengers traveling together. It is generated each time a flight, train, or other travel service is booked. The PNR typically includes the passengers name, contact details for the travel agent or airline office, ticketing details, and the itinerary of at least one segment of the journey. The PNR is identified in the database by a record locator, which serves as a unique code for the document in the airlines or travel agents database. PNRs are essential for booking confirmation, managing travel itineraries, and are also used for security and law enforcement purposes, such as preventing, detecting, and investigating terrorist offenses and related crimes that are transnational in nature.
