Yes, that is the part that would keep me awake at night. With my luck they would most certainly change that the day of my departure. I would still just route my trip through Frankfurt and sleep better. I, personally, am done with RSA. Zim too. I like Namibia, TZ, and Burkina Faso deserves a good hard look, too. That's just the way I feel - I am sure a lot of people would disagree.
