Abstract: The present invention is directed to method and apparatus forming a system for deriving from computer-based travel reservations systems specific cost and time information, on per-unit basis, such that accurate cost information may be produced for comparison purposes. Using a programmable computer under control of a program instruction set, individual data segments of a given trip between two points (origination-to-destination) is reduced to a common per-unit basis permitting uniform comparison and analysis. The process identifies each trip having an origination and destination by a unique name, determines the number of connecting segments flown, the number of miles flown, the amount of time from departure to arrival, and the costs on per-hour and per-mile basis.
