They could be connecting on the South African Airlines/Swiss Air connection via Johannesburg to Victoria Falls that would have arrived at 1230pm today:
SA/LX 7241 ZRHJNB 2240 0910‡1
SA 40 JNBVFA 1050 1230
or this nearly identical combination to Harare:
LX 288 ZRHJNB 2240 0910‡1
SA 22 JNBHRE 1045 1215
I can't imagine they'd stay in Vic Falls since they were just there with the Reporters, but from there it's a half hour drive to Chobe, Botswana.
