摘要

An optional tour agency organizing optional tours that are combined with an airline ticket-hotel reservation package at a customer's discretion is provided with booking state information. Optional tour agencies located in various places and organizing optional tours refer to a booking information aggregating device for travel booking information. Each optional tour agency accesses the booking information aggregating device (101) from a terminal device (102) to refer to booking information under specified extraction conditions. The booking information aggregating device (101) sends a result of aggregation performed under the extraction conditions to the terminal device.
