Has anyone found a solution to this? I tried today and I get the same error. I linked my BA and QA accounts. I then transferred all the points needed for this booking from BA to QA and tried to book it and I am still getting this same error: You must have at least 50% of the Avios needed to book an award flight. To continue, please select ‘Pay now’,
Should we unlink the Avios accounts and then try to book it?
