I've been an Platinum (USA) cardmember since 2006. Have personal plat, biz plat and gold, and a corporate account. I've been nagging for a Centurion card for some time with no luck.

I'm wondering if when Centurion reviews the account, do they look at spend on personal and business or only business, if you are request business Centurion? My business card has the volume but my personal has the "type" of spend they like.
