Availability Display and Reservation (PNR)
Users access an airline’s inventory through an availability display. It contains all offered flights for a particular city-pair with their available seats in the different booking classes. This display contains flights which are operated by the airline itself as well as code share flights which are operated in co-operation with another airline. If the city pair is not one on which the airline offers service it may display a connection using its own flights or display the flights of other airlines. The availability of seats of other airlines is updated through standard industry interfaces. Depending on the type of co-operation it supports access to the last seat (last seat availability) in real-time. reservations for individual passengers or groups are stored in a so-called passenger name record (PNR). Among other data, the PNR contains personal information such as name, contact information or special services requests (SSRs) e.g. for a vegetarian meal, as well as the flights (segments) and issued tickets. Some reservation systems also allow to store customer data in profiles to avoid data re-entry each time a new reservation is made for a known passenger. In addition most systems have interfaces to CRM systems or customer loyalty applications (aka frequent traveler systems). Before a flight departs the so-called passenger name list (PNL) is handed over to the departure control system that is used to check-in passengers and baggage. Reservation data such as the number of booked passengers and special service requests is also transferred to flight operations systems, crew management and catering systems. Once a flight has departed the reservation system is updated with a list of the checked-in passengers (e.g. passengers who had a reservation but did not check in (no shows) and passengers who checked in, but didn’t have a reservation (go shows)). Finally data needed for revenue accounting and reporting is handed over to administrative systems.

Famous quotes containing the words availability, display and/or reservation:
“Since ... six weeks ago, there has been no day in which I have not had letters and visits on the subject of my nomination for the Presidency.... I say very little. I have in no instance encouraged any one to work to that end.... I have said the whole talk about me is on the score of availability. Let availability do the work then.”
—Rutherford Birchard Hayes (1822–1893)
“Housekeeping is not beautiful; it cheers and raises neither the husband, the wife, nor the child; neither the host nor the guest; it oppresses women. A house kept to the end of prudence is laborious without joy; a house kept to the end of display is impossible to all but a few women, and their success is dearly bought.”
—Ralph Waldo Emerson (1803–1882)
“Music is so much a part of their daily lives that if an Indian visits another reservation one of the first questions asked on his return is: “What new songs did you learn?””
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
