Abstract: An automated system and a method for checking an already issued airline ticket prior to having a requester submitting a change request of the already issued airline ticket are described. The system comprises a ticket data retriever unit for retrieving, with a ticket reference provided by the requester, the already issued airline ticket from a ticket database. Then, an issued fare rule finder element retrieves, from a rule database, one or more rule scenarios applying to the already issued airline ticket and governing what changes are permitted. After which a decision module element combines the one or more rule scenarios into a set of permitted options and restrictions and deliver them to the requester. Hence, the requester knows all about the permitted options and restrictions prior to actually requesting to change the already issued airline ticket.

Abstract: A ticket change constrainer which allows reissuing or revalidating an already issued airline ticket includes a ticket change domain reducer operable to reduce an input search domain of change opportunities on the basis of change conditions set in the already issued ticket. It also includes a ticket change valuer operable to weigh the change opportunities of the reduced search domain and to return a reduced valued search domain of change opportunities. The weighing of the change opportunities is done on the basis of pricing method popularity scores updated in a ticket change memory by a ticket change watcher agent from actual change transactions handled by the system. The change conditions include standard pricing methods of the airline industry. The input search domain of change opportunities is produced by a conventional fare-driven search engine on the basis of a ticket change request issued by an end-user of the system.
