Abstract: A time-sensitive, data reduction system is described. According to an aspect of the system, a method is disclosed that comprises: receiving at least a portion of an airline-specific dataset, wherein the airline-specific dataset comprises a plurality of location records, wherein each location record comprises a point of interest (POI) and a unique rank, wherein the POI is defined by unique geographic identifier; determining a current position of the aircraft; and based on the current position and based on the unique rank of each of the plurality of location records, controlling, at a passenger display in the aircraft, a presentation of a map and a plurality of POI indicators associated with a highly-ranked subset of the plurality of location records. According to another aspect of the system, a plurality of servers are used provide relevant location-related content to an aircraft passenger.

Abstract: A real-time multimodal travel estimation and routing system having a first mode for air-based travel and a second mode for ground-based travel, and a method for estimating a time of arrival to a ground-based destination having a first mode for air-based travel and a second mode for ground-based travel is disclosed. The real-time multimodal travel estimation and routing system is configured to receive an input designating a ground-based destination, a request for an available ground-based travel option, and display an estimated time of arrival to the ground-based destination based on first data stored on-board the aircraft for the second mode and real-time flight information for the aircraft for the first mode. The system is further configured to receive an update of real-time information for the available ground-based travel option and update the first data stored on-board the aircraft.
