Thanks!It's the kind of thing you might do if you were a few thousand points short of a great redemption and you want to leverage the value of the points you already have - but it's probably not good value when you're looking to buy the whole fare in points. BA does offer an Avios subscription that comes in at about 2c per Avios, but you have to wait a year for your Avios to trickle through in monthly instalments. It used to be nearer 1.7c per Avios but they put the price up and the Australian dollar continues to fall. That was almost tempting (Avios gives you access to the QR network) but not quite. I have no idea about AA points but I doubt they would be better value.
