Those numbers are around the plane's cruise speed. But the plane should not be traveling at a speed around its cruising speed, since we know that on long haul flights planes across the oceans planes use jet streams to reach their location. It would be traveling the plane's cruising speed + jet stream.
Jetstreams even enable supersonic flight for commercial aircraft.
On the flight trackers there have been some interesting anomalies. Jeran shows at the 1h32m mark of the following video about the flight between Auckland and Santiago that True Airspeed can be seen to far exceed ground speed. Over the course of the flight the True Airspeed is either "N/A" or shows quite fast speeds.

A jetstream is just a wind, and I accounted for it in my calculation. A look at any jetstream map will show that they are predominently westerly in the southern hemisphere, which corresponds with my previous statement and, if it is assisting the eastbound flight will it not be hindering the westbound which is occuring simultaneously and at similar latitudes?
We've also done Jeran's thing before. Simultaneous to the "supersonic" speeds is a series of altitude changes which an F-16 would struggle with. Its just a batch of missing data on aircraft position; when it recovers the position data it integrates the delta-position over time to determine speed.
