We are flying Atlanta to Johannesburg next week arriving at 6:50 p.m., the last flight out to Cape Town is at 9:00 p.m. It is on South African Airways. We are flying in Business Elite, so I imagine we will be able to exit the plane early on. Can we check our bags straight through to Cape Town? If not, we will have to reclaim them and recheck in Johannesburg. Will we have time to make the connection??? Thanks!!
