As someone who does part pay with Avios, this is useful to know. I know it's not for everyone (or the most efficient way to use them), but I use it to make Club SH more affordable while accruing status for when I travel LH - normally below Club. So this is potentially a motivation to be a bit more creative in accruing Avios, for me at least.

There's a small devaluation built in here; 10,400 used to get £70 off, now 10,160 takes £68 off. But it's less than a penny, I think.
