Lucas, is this for real or just your suggestion? When Varig first started HK flight, they initially planned Rio-Nairobi-HK, but rerouted through Rio-Jo'burg-Bangkok-HK. IMO this is not very practical, any flight with more than one stop means you're wasting too much time on landing/take-off plus landing charge.

BTW, this is my first post and you've started some really good thread and can't believe no one is posting.
