While I understand the appeal as a way to get a very general baseline, I don't like getting too in the weeds over CPM. My best redemptions would in theory be silly things like last minute YVR-YXS in Y for 5500 points that AC was trying to sell for nearly $1000. Which is really boring.
I have no idea what the cash cost of my LHR-AUH flight in Ethiad F on the A380 would have been and don't really care, happy to have paid 65000 points for it though, and will do so again if it's ever possible.
