What is PNR and what data does it contain?
The Passenger Name Record (PNR) is the generic name given to the files created by the airlines for each journey any passenger books. They are stored in the airlines’ reservation and departure control databases. PNR allows all the different agents within the air industry (from the travel agent and the computer reservation systems (CRS) to the carrier and the handling agents at the airports) to recognise each passenger and have access to all relevant information related to his/her journey: departure and return flights, connecting flights (if any), special services required on board the flight, etc. The number and nature of fields of information in a PNR system will vary from airline to airline and from passenger to passenger and could expand to approximately 60 fields and sub-fields.
