May I ask what others are using for PayMe? I'm using Citi Prestige at the moment, but based on the hongkongcard post, seems like I should first max out HK$25K of CCB Eye on this (being the gap between the quota for extra 2x on Overseas/Travel and quota for extra 4x on Online/Paywave), since that would net me HK$3/AM.
I would miss out on the HK$3/AM on any other Online/PayWave spend, but the opportunity cost lost there would not be as high, since BEA FlyerWorld is HK$5/AM and Citi Prestige is HK$6/AM (+AR bonus) for PayMe.
Am I missing anything here?
