  • Publication number: 20070073562
    Abstract: A system, method, and computer program product provide and display travel information in response to a request from a user. The travel information may be obtained from many different sources, such as trip journal websites, and may comprise complete or partial travel itineraries, as well as textual, audio, or video descriptions, ratings, photographs, and other useful information related to geographic destinations, components, points of interest, transportation methods and providers, and the like. The user may select bookable and non-bookable components, or a complete or partial itinerary, that the user desires to incorporate into an itinerary. The price and availability of each selected component may be determined and displayed. An optimized schedule may be suggested for the selected components. The bookable items may be booked by transmitting information to a global distribution system. The user itinerary may then be stored for use as travel information for a future user request.

  • Patent number: 7050987
    Abstract: The methods and systems for coordinating the travel itineraries of multiple travelers, who are leaving from more than one origin location, but are arriving at the same destination location, provide automated techniques for determining which itineraries for each traveler best meets the specified criteria for the trip. For example, a travel organizer may specify certain travel criteria for a trip, such as the relative importance of the travel schedules versus the price. A set of suggested travel itineraries that most closely meet the specified criteria are then provided, in addition to the amount of time between when any two travelers arrive at and/or leave from the destination location, and the price. Furthermore, the travel coordination techniques provide flexibility by allowing replacement of one or more of the suggested itineraries with other possible itineraries and recalculation of the time amounts and the price(s).

  • Publication number: 20060106655
    Abstract: A method for coordinating outbound and inbound itineraries for a plurality of travelers is provided. Such a method comprises receiving a destination location, a plurality of origin locations, and travel information, wherein each origin location is associated with at least one traveler. A set of suggested outbound and inbound itineraries between each origin location and the destination location is then determined, based upon the travel information, from a travel database comprising at least outbound and inbound itineraries between the origin locations and the destination location, wherein each suggested outbound and inbound itinerary comprises an arrival time and a departure time with respect to the destination location, and the set of suggested outbound and inbound itineraries collectively provides an optimal time together of the travelers at the destination location. Associated systems and methods are also provided.

  • Publication number: 20030225600
    Abstract: Methods, systems, and articles of manufacture consistent with certain principles related to the present invention determine an impact of schedule changes on passenger flow and re-accommodate disrupted passengers. A passenger flow re-accommodation process is performed that determines a value for a disrupted passenger based on selected criteria and rules that may be established by travel service providers. The value and available travel service information are used by the process to rebook the disrupted passenger on a selected alternative itinerary. A notification of a successful rebooking may be provided to the disrupted passenger and/or the travel service provider.

  • Publication number: 20030171990
    Abstract: Methods, systems, and articles of manufacture consistent with certain principles related to the present invention enable a computing system to manage the delivery of web content based on historical site visit data and revenue optimization processes. In one aspect consistent with certain features related to the present invention, a publisher may provide ad campaigns that target various criteria. The publisher may be configured to allocate impressions of web content based on forecasted site visits and impressions for future months. The impression allocations may be adjusted based on overlapping targeting criteria between the campaigns and a prediction of whether a campaign may reach an impression goal before the expiration of the campaign's run period. The impression allocations are also adjusted by expected revenue from clicks and revenue per impression for different campaigns.
