Hi,

I know that it is impossible to keep churning AMEX card application, but I was under the impression that I could at least get just the "difference" in sign up bonus. I opened an SPG personal credit card long time ago (in 2005) and closed after I got the 4k bonus. Now AMEX is widely advertising the 10K sign-up bonus, and I signed up just hoping I could get the 6k in difference, however, I was denied for any enrollment points and was told it is just for new user, whatever the points I got last time is all I could get my whole lifetime. I do not remember from what source that I got into that "false" assumption (difference in points), but is it never the case at all?

Thanks
