What does a passenger name record (PNR) contain?

A passenger name record (PNR) is crucial in travel logistics as it serves as a digital file that contains all the reservation details for a passenger. This includes critical information such as the passenger's name, itinerary, contact information, special requests, and any associated services like baggage allowances and meal preferences. The PNR ensures that all aspects of the passenger's travel arrangements are organized and accessible to airlines, travel agents, and associated service providers.

The other options address aspects related to travel but do not pertain directly to what a PNR encapsulates. Flight delay information is typically handled by the airline's operational systems and is not a component of a PNR. Hotel room availability is related to hotel management systems and does not fall under the PNR data structure. Similarly, payment processing information is usually stored separately due to privacy and security regulations, and it is not confined to the PNR itself.
