I understand your frustration but we are not all here to make your life difficult. You may be familiar with the costs and process but I am sure you have had instances in your life where you had to make something pretty clear before someone else (partner or colleagues) would fully understand the message your were trying to deliver. (I am guilty as an introvert myself).
We are not asking for too much here. It would be much appreciate in the future to outline the details a bit more and it would be happy days.
Not saying my way is the best/perfect way, but personally, I would have gone something that sounds a bit like this:
Hey guys, I used 325,000 Qantas points and $1100 to redeem 5 oneway economy seats in December for a ski trip. We will be flying BNE-NRT-YVR (or Brisbane-Tokyo-Vancouver). Flying Qantas and then Japan Airlines.
I checked on Skyscanner and the flights would have costed my $31800 if bought with cash. We were thrilled to have paid $1100 instead of $31800. Sounds like great value to me what do you think? Why does it costs so much to fly Japan Airlines?
All the info would be there for us to comment.
Points to note is:
Your Qantas points cost something even if you have earned it for ‘free’. So to ignore it in any equation is gonna make you feel over the moon as you felt like you saved $30k.
In reality, the simplest way to valuate your point value is ($31800-$1100)/325000 QF pts =9.4cpp. This would be a great cpp value at first glance.
However, another train of thought worth considering is, value pricing. Would you have paid $31800 to take the same flight anyway? I would hazard a guess that you wouldn’t. The way value pricing works is assessing that against how much you would have paid anyway.
Say you would have paid $1500 per person anyway, the calcs would be:
($1500 x 5 -$1100)/325000 QF pts = 2.3cpp. Which is still a reasonable redemption, in my opinion.
