We are flying to Luanda in September then a Taag flight to Windhoek en route to Botswana. There was no availability to SA so this was an alternative. I hope that the 5 hr gap is long enough to make sure we get our connection but if everything goes smoothly we may have a long wait in what looks to be a pretty grim airport.
I'd like to see Lusaka or Dar coming back to give more options other than SA although Durban is a good place to get a bunny chow.
