The underlying problem is that the current demand is based on data from 2006 or older (depending on airports) and calculated upwards at 5% p.a. (If I recall correctly)
As far as I am informed, there will be no changes to the demand system before city based demand which in Sami's mind (and thus far many/most people's expectations) will fix most/all of the above issues.
There are a couple of places where demand is botched, especially in markets like Turkey. Other markets are way over the top, e.g. LHR where in real life a lot of people connect. In AWS you have those passengers "double" because of the way data is processed. Not sure if Sami downsized that for connection airports by now, but last I know it hasn't been done.
So for now, we'll have to continue our wait for city based demand, to see how things are being affected
