It does indeed look like BA/Comair would be better for me if I fly to Windhoek (or Harare again) this year (well, they look like the only alternative to SAA, whom I'd really like to avoid from hereon). Only possible downside is that it's not entirely unknown for Corporate Travel Agent From Hell to find a BA flight into JNB and then an SAA Airlink flight onwards (that's just one of their many little tricks to make business travel harder than need be).
