Plane Flights

Based on the map and information given on this site I have noticed an issue with the idea of the FE theory and thought it best to get some feedback from believers.  Its a bit of a read so i appreciate all that read through this.

This theory seems to be largely based around the northern hemisphere being the centre of the earth and thus all globes are designed accordingly.  In the map of the flat earth the southern hemisphere would have to become enlarged.  An obvious explanation would be that the land masses are the correct sizes and that amount of water between land masses in the southern hemispheres would be misrepresented to maintain the conspiracy.

So the main points from the above:  The distances in the northern hemisphere are correct compared to a globe but the southern hemisphere would need to be enlarged (perhaps just in distances between landmasses).

So why is it that when you take plane flights in the southern hemisphere to places using RE theory distances (which would be very different distances to FE theory distances) but still achieve the correct, shorter, flight times?  No conspiracy could make a plane fly that much faster.  Doesn't this completely bust the FE theory of the globe?

Sorry, they can't actually answer this one. Doesn't fit in with their conspiracy.
There was a thread a couple days back where someone pointed out that flights from Australia to Africa would be horribly long...

Tom himself posted something along the lines of "Oh, but how many direct flights do you see from Australia to Africa..."

When I pointed out there's at least 10 a day by multiple airlines and also almost 20 more from South America to Africa, all direct flights mind you, the thread just died.

I also participated in a thread where we discussed picking a random point on the globe, and flying in a straight line in any direction from that point. Our point was the flight times would be approximately the same no matter which direction you flew.

Well, instead of getting a response to that one we've gotten 3 days of some (retarted? dense?)  forum mod that can't read the whole post and only posts things like "Oh, well how you know you're going straight." And "Oh, if you went straight east or west it works in FE..." rather than actually answering the question.
