I think they have shot themselves in the foot.
I will now be doing less surveys, as once I get to the 3500 points mark(1000) avios I will stop doing surveys, as there is no incentive to do more than that a month.Previously, I would do enough surveys to redeem(on average) 6500 per month.I am currently sitting on enough points that under the new system will take me three months to redeem.So there is no reason for me to do any surveys until the new year.
