Since airline reservation systems are business critical applications, and they are functionally quite complex, the operation of an in-house airline reservation system is relatively expensive. Prior to deregulation [clarification needed], airlines owned their own reservation systems with travel agents subscribing to them. Today, the GDS are run ...
Diagrams created to represent attributes as well as entities and relationships may be called entity-attribute-relationship diagrams, rather than entity–relationship models. An ER model is typically implemented as a database. In a simple relational database implementation, each row of a table represents one instance of an entity type, and each ...
Today, DCS mostly (98%) manage e-tickets using interfaces from a number of devices, including check-in kiosks, online check-in, mobile boarding cards, and baggage handling. DCS are able to identify, capture and update reservations from an airline's computer reservation system for passengers stored in a so-called passenger name record (PNR). A ...

Fearful this would place too much power in the hands of agents, American Airlines executive Robert Crandall proposed creating an industry-wide computer reservation system to be a central ...
A mirror image of the passenger name record (PNR) in the airline reservations system is maintained in the GDS system. If a passenger books an itinerary containing air segments of multiple airlines through a travel agency, the passenger name record in the GDS system would hold information on their entire itinerary, while each airline they fly on would only have a portion of the itinerary that ...
