I've found really good airfare deals on SAA directly from the website but I've never booked it as I have been waiting for this partnership to gel. I don't know much about their airline. Perhaps with the *Alliance being official there will be some introductory fares or it will just be more on the fare radar on FT. There isn't a whole lot of discussion about travel to/from Africa here, or at least not as much as Asia.
I for one have been dying to get to CPT so this makes me very happy! Of course EQMs have to be part of the deal.
