Abstract: A method and system for displaying fare availability involves receiving an identification of an origination location and a destination location for generating a travel itinerary. An availability for each of multiple fare classes is determined for each of multiple time periods. The availability corresponds to the origination location and the destination location. A calendar having a representation of the multiple time periods is displayed. The calendar includes a visual indication of one or more available fare classes for each of the multiple time periods. The calendar can display real time or substantially real time availability information for one or more fare classes.

Abstract: A system and method for changing a travel itinerary include receiving a request to make a change to a first travel itinerary that includes at least one segment, displaying an identification of one or more alternative segments, receiving a user selection of one of the alternative segments, modifying the first itinerary to include a reservation for the selected alternative segment, and releasing the segment of the first itinerary to be replaced by the selected alternative segments. The system and method may also include calculating a fare difference between the one or more alternative segments and the original segment to be replaced.
