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.
