You're almost close enough to fly to Europe, then to SA. You then have some decent FC options, ones you know anyway. Just remember that even BA has no FC to many SA destinations, and keep F mostly on 747-400 to the region. Almost all the carriers into the continent seem to be shedding F as fast as they can. I have very fond memories of both JJ and LA FC, even the former glories of legacy Varig. All of thsoe are kaput. If you really want to go out of the way you can take EK to DXB thence GRU, F all the way. Direct will not do.
