Abstract: An unspecified-time airline ticket representing a purchased seat on a flight to be selected later, by the airlines, for a traveler-specified itinerary (e.g., NY to LA on March 3rd) is disclosed. Various methods and systems for matching an unspecified-time ticket with a flight are also disclosed. An exemplary method includes: (1) making available an unspecified-time ticket; (2) examining a plurality of flights which would fulfill the terms of the unspecified-time ticket to determine which flight to select; and (3) providing notification of the selected flight prior to departure. The disclosed embodiments provide travelers with reduced airfare in return for flight-time flexibility and, in turn, permits airlines to fill seats that would have otherwise gone unbooked.
