recently did a little research and am still trying to find out about SA flights numbered 0040 and 0041 JNB/VFA/JNB not sure if they're codeshare or not.
we have ID95 but confirmed tkts are pretty cheap when avail. seems there is only one flt per day, tho.
Policy now is that if you cross to zambia you pay visa (if I'm getting that right) so it has to pay off staying on Zim side. The poverty is apparently quite gut-wrenching with the market vendors who want to sell you anything [but don't beg]. The hotel of interest to me is in Zim and I understand there is no view on Zam side.
I'm working on more stuff--trip is not until Sept tho. Please keep adding to this thread as you find info!
