<p>An advanced online reservation system that provides many of the services a traveler would expect from a travel agent is described. The online reservation system constructs a fare ladder (i.e. a listing of fares corresponding to the traveler's requested itinerary) that shows available fares, that is, fares for which seats are still available. The fare ladder can include fares listed by selected airlines, and special contract fares. The online reservation system translates Computerized Reservation System (CRS) codes used by professional travel agents into language that is more easily understood by a typical traveler. The online reservation system also checks rules associated with available, discounted, and/or negotiated fares to produce a list of qualified fares. The traveler can choose to view qualified or non-qualified fares.</p> |
