c) Award seats in premium cabins are arguably filled by a disproportionately high number of frequent flyers who read blogs and especially forums like FT, where they get wise to the fact that redeeming using AS miles is much cheaper. Why do I say that? Because the more often you fly, the more likely you are to become i) interested in and ii) familiar with your own and perhaps even other airlines' FFP.

I guess one other reason why there is a lot of "hostility" towards people who use AS miles to redeem CX F is that Cathay Pacific has made it possible for AS members to redeem at such low rates in the first place.
