The SA proposal has something as after the World Cup they should have some new hotels and maybe renovated airports?
I have no idea of the size of "Springbok Airlines" at their hub, but could imagine that a charter there could bring us to really interesting places.

But I guess SA would be the only airline/destination on that part of the world, right?

Concerning the visit of several *A-Hubs, I guess Asia might be most interesting besides some European Carriers. I still like the idea of flying round the mediterranean sea....!

Asia would mean long positioning flights for most attendees, I guess?
