Abstract: Methods, apparatus, and computer program products for modifying re-accommodations. A report characterizing execution of a re-accommodation may be stored in a report database. The report may include an impacted Passenger Name Record (PNR) table that associates each PNR impacted by the re-accommodation with an identifier. The identifier may identify an envelope in a history file comprising a portion of the history file that documents changes made to the PNR by the re-accommodation. In response to receiving a request to modify the re-accommodation, the report may be retrieved from the report database. PNRs impacted by the previous re-accommodation, and changes made to each PNR, may be determined using data in the impacted PNR table and the history files of the PNRs. The impacted PNR table may thereby enable building and execution of a modifying re-accommodation that selectively undoes or redoes a previously executed re-accommodation to implement new solutions to scheduling changes.

Abstract: Methods, systems, and computer program products for building customized packages based upon a disruption impacting an itinerary. Packages may contain a travel solution and a service. The content of each package may be based up on data relating to passenger preferences, data relating to trip context, and availability data retrieved from an availability database, as well as policy-building rules.

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.
