South African operates ATL & JFK to JNB and CPT. About 8000 miles each. I did the ATL-JNB route there and back in the upper deck. (Where they have economy and not business class.) Needless to say I felt like shooting someone when I got off that plane. My ass became a whole new shape, and I LOVE flying because I am a private pilot. On the way home, the big Springbok 744 had to stop at Verde in the middle of the Southern Atlantic to refuel so we could get to ATL. Many people became distressed because they did not know this leg had a fuel stop and thought we were having an emergency.
