I looked at a route I frequently fly for January, and likewise the price has gone up by 750 avios. At the what is the now the RFS rate of 50p it is now 9750 one way instead of 9000. It is not that long ago that they increased from the 8000 avios when they first introduced this 50p rate.
Over the past weeks I have been happily converting nectar points to avios, but this is now making me think I should be sending them in the opposite direction.
