I just got a platinum card and when I did the online activation, it wouldn't let me add it to my existing online Amex account and insisted that I set up a new account just for the platinum card. I've always been able to combine all of my Amex cards into one online account. So, is this something new or something specific to the platinum card? I want to combine them since I currently have a bunch of MR points on another card that I was thinking of cancelling soon. I guess I'll have to give them a call but was wondering if anyone else had a similar experience.
