I haven't tried it, but I got a copy of its T&C http://www.asia.ccb.com/hongkong/per...p_premier.html and the redemption form https://online.asia.ccb.com/Personal...Redemption.pdf

T&C clause 4 suggests online bill payment is a Designated Transaction (just like CUP) capped at 12 times credit limit bonus point earn.

But it does not mention the specific earn rate, so I assume it will be general earn rate of 2 bonus points per $1 paid from clause 1.

The redemption form does not have clause 4. I cannot tell which one is newer but I prefer the harsher set of terms (the T&C).

I won't sacrifice a $7.89/mile earn rate when half the miles are in Rewardcash (hopefully Avios at 18 Avios per RC!) for a $7.5/mile earn rate all in Asia Miles, so I will not use it.
