I can book SYD to SIN, SIN to DXB, DXB to SYD in Business class for 3 of us in April 2021 using my Qantas points flying on British Airways and Emirates. As Classic Rewards is free to cancel until 31 October 2020, if I cancel after that date, is it 7,700 points per person each flight? If British Airways and Emirates still decides to fly but I don't want to risk it come April 2021, am I up for 23,100 points or 69,300 points should I wish to cancel the 3 flights for the 3 of us. Plus do I get back the $2000 in taxes that I have paid.
