My instinct and nothing more is telling me that this is coming as it feels a natural next step. BA appears to be following, rather than being innovative and leading, and so copying the path other airlines have already gone down looks inevitable. I try and maintain enough Avios for a years with of planned usage - nothing more. We had intended to move a bunch of HSBC points from Mrs Bubbles card during the transfer bonus window that has just closed but have held off for now and adopting a bit more of a wait and see approach. Similarly, I have never used the Avios booster but the fear of the unknown from dynamic pricing caused me to hold off on that when otherwise I may have taken advantage of it. Nectar auto transfers have also been stopped. I am holding onto the BAPP card for now as I still see real value in that but that could change if/when dynamic pricing comes in and how BA operate it.
