Booked qf63 qf64 Sydneyto Johannesburg Premium economy
June 2016 on special $400 off
Then applied to upgrade to Business 35000 points per trip
My wife and I .Had no trouble getting the upgrade both ways
For 2 people and we are only Silver
Excellent use of points,fantastic service great food lie flat
Qantas seats got great sleep both ways
Older 747Jumbo but fully upgraded
Would recommended upstairs ,very private only 24 seats;
I don't think too many businessmen fly this route ,so
Upgrade not competitive, maybe more in school holidays
Qantas was fantastic
