People have shared a number of reasons why a FR is a 'big deal.'
I've been fortunate enough to never get FR or AA, so it would be a big deal to me simply because I have over a dozen creditors who have never done it. If Amex or another creditor requested an FR I would likely close the account and tell them to take a flying leap(Except for Penfed maybe )
I've only been with Amex for about a year so if she stops putting out, I have other options.
