FlightRadar24 and FlightAware Track Aircraft Flights

FlightRadar24.com shows aircraft positions around the world - most European craft are displayed in real time, while U.S. aircraft generally have a five minute delay. For tracking a particular U.S. flight, FlightAware.com offers the option of showing the aircraft's actual departure time, flight path and updated estimated time of arrival (ETA) of a scheduled U.S. commercial flight. The latter feature is useful if you are meeting someone at the airport.
