And - I think I remember Ngaire saying they flew SAA last time they went to South Africa, which was only a month or so ago. My recollection is that she thought it was wonderful, they few I think Biz class and she mentioned they even had rack of lamb - but I can't remember where she posted that, and I don't usually have very good luck doing searches. You might give her a call or email with your questions.

Editing to add: never mind Andi, I found her post and it was BA, and they flew first class. Its under seamail "I am in Africa".
