San Francisco to Auckland:

On this leg of the journey, live tracking will stop once the flight leaves North American radar, but you should continue to receive updated information as described below:

Flight Aware links show the current/latest flight, and should track the flight on radar until just south of the equator. After that additional information may not be available, so try FlightStats.

FlightStats links customize to our specific flights, and will likely only provide radar coverage until shortly after the flight leaves the North American mainland (about 30-45 minutes after the departure from San Francisco). Continue to monitor this page for updated flight information until the flight lands in Auckland.
