What you are talking about is the difference between True Airspeed (TAS) and Indicated Airspeed (IAS).  IAS is what is shown on the pilot's Airspeed Indicator, and is important for the aerodynamic handling of the aircraft, but at high altitude it is significantly lower than the TAS.  If you like, IAS is the number of cookies per second, but is less than the actual speed.  TAS is used for navigation, and is the maximum speed quoted by the manufacturer. 

What this means in practice is that the aircraft is faster at altitude, as you suggest, but this is already the limiting speed quoted by the manufacturer.  If the limiting TAS is, say 500 knots, the pilot might reach this speed when he sees only around 300 kts on the Airspeed Indicator. 

Its not that the aircraft is exceeding this limiting speed at high altitude (low air density), its just that the pilot is actually seeing a lower figure for IAS.  The minimum air density (in other words is maximum altitude) is specified, again, by the manufacturer. 

It is quite categorical.  The aircraft will not travel through the air, at any density which it is certified, faster than the manufacturer says.

This is a great response...  I don't have an answer.    ::) :o ;D
From the surface Earth looks flat.  From space Earth looks round.  Now what?

...Generally winds play a bigger factor as you head south into thicker atmospheres.

The atmosphere is not particularly "thicker" in the southern hemisphere.  The density of the
atmosphere changes with altitude, not location.

The Qantas Santiago Chile to Aukland NewZealand flight is pretty close.
It was (not is — Qantas has not operated that route in over a year) nowhere near close. At its southermost point, it passed around 4000 km from the south pole.

Why does that flight not fly due west?
Plus there are the many circumnavigations of Antarctica by ship that do not take nearly the needed time to go around the disk of the FE model.
There of course have been many expeditions to Antartica with no evidence of the ice wall that would have to be extremely high (100 mies?) to contain the atmosphere and hence be easy to see.
Irrelevant. If you want to discuss a different topic, you can create another thread for that. Do you have evidence for your claims regarding flying over the south pole or not?
Not true. Wise once claimed that Qantas killed one million passengers in order to hide up the fact that earth is flat.
