After Saturday's Qantas 789 Sydney / Johannesburg QF63/QF64 rotation was initially delayed for 25+ hours, there was a further disruption to the return QF64 leg, with a diversion to Durban shortly after take off. This being the first visit of a Qantas 787-9 to that airport.
The flight resumed after just over an hour on the ground, arriving in Sydney at 16:15 AEST on 2nd - 28 hours late versus the timetable.
Flightradar24 doesn't seem to have caught up with the situation, while FlightAware having initially lost the plot, seems to be predicting a further occurrence of the diversion on the next two flights ????
