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.
