Abstract: A flight-ticket price may be monitored by obtaining an itinerary record associated with a previously-booked flight itinerary, identifying a group of flight segments that corresponds to a ticket, “fingerprinting” the ticket, and determining a schedule to periodically monitor prices associated with the ticket. During at least one price-monitoring period, an up-to-date version of the itinerary record is obtained and “fingerprinted”. The “fingerprints” are used to verify that the flight ticket has not changed significantly, current pricing data is obtained, and a cost saving is determined to be currently obtainable, considering possible change penalties, by re-ticketing or re-booking the group of flight segments.
