My wife just took a last shot at Platinum card and also got the same "our records indicate that you have recently submitted more than one application for American Express card(s), therefore this request has been cancelled."
I had applied the same time for a Chase card so they won't see the inquiries of eachother.
The question is, if I wait out for the Chase response (wasn't instant decision) and it's after March 31, will Amex still accept a reconsideration if I have a reference number from before the 31st? That would allow Amex to make pull in new month for me and better my chances of acceptance. Otherwise, I would call Amex now to reconsider and the heck with Chase.
