Abstract: Methods, systems, and computer program products for managing inventory availability for travel inventory items associated with travel services. An inventory request is received at an inventory system for at least one travel inventory item that includes a corporate identifier and corporate value data associated with a passenger name record from a reservation system. Availability for the at least one travel inventory item is determined. The availability is determined by determining an effective yield for the at least one travel inventory item based on the corporate value data, where the availability is based at least in part on the effective yield. An availability response is communicated to the reservation system that includes the determined availability for the at least one travel item.

Abstract: Methods, systems and computer program products for processing a travel request. A travel request is received at a reservation system that identifies a travel inventory item and a passenger name record. Whether the passenger name record includes a corporate identifier is determined. If the passenger name record includes a corporate identifier, corporate value data is determined, and an availability request that includes the corporate identifier and the corporate value data is communicated to at least one inventory system associated with the at least one travel inventory item. An availability response is received that indicates a determined availability for the at least one travel inventory item, where the determined availability is based at least in part on the corporate identifier and corporate value data.

Abstract: Methods, systems, and computer program products for assigning seats of passenger-transport vehicles to passengers. The passengers are subdivided into a plurality of groups. The passengers included in each group are connected by social-network relations and have less than a maximum number of social-network relations to other passengers outside of the group. Breaks of the social-network relations between the passengers are minimized when the passengers are subdivided into the groups. In response to one of the passengers being excluded from the groups, one of the groups is determined that includes at least one included passenger with at least one of the social-network relations to the excluded passenger to thereby increase the size of the group by adding the excluded passenger.

Abstract: Methods, systems, and computer program products for managing the booking of travel inventory items at an inventory system. A booking request for a type of travel inventory item managed by the inventory system may be received at the inventory system. An expiration time may be determined based at least in part on the booking request, and a travel booking for a travel inventory item of the type may be confirmed based at least in part on the booking request. The inventory system may be updated based on the booked travel inventory item.

Abstract: Systems, methods, and computer program products for analyzing itineraries to re-accommodate passengers in the event of a flight schedule change. A schedule change is received for an impacted flight and a plurality of original itineraries that include the impacted flight are identified. The computer reservation system is used to simulate application of a default travel solution that replaces the impacted flight in the original itinerary of each passenger to define a replacement itinerary. Each replacement itinerary is assessed for compliance with a plurality of validity conditions. For each replacement itinerary that fails to comply with at least one of the validity conditions, one or more replacement travel solutions are computed each connecting the origin location with the destination location and each subject to satisfying at least one constraint on one or more flights comprising each replacement travel solution.

Abstract: In a method for automatically mapping a cabin and travel class structure of an disrupted flight into replacement flights, cabin and travel class structure of the disrupted flight are retrieved. For each affected passenger, a base disrupted flight is determined from the passenger itinerary. For the disruption period, cabin and travel class structure of the replacement flights are split into sub-periods. For each sub-period, mapping begins by establishing a direct match between cabin and travel class structures. The direct match is validated against actual cabin and travel class structure of the replacement flights, including pinpointing all found discrepancies. All class matching tables (CMTs) applying to the disrupted flight and disruption period considered are retrieved from a rule repository. Cabin and travel class structure of the replacement flights are further split in sub-periods to imbed the actual validity periods of retrieved CMTs. Rules of the retrieved CMTs resolve all found discrepancies.
