Does this also apply to the Green charge card? (spend and PIF) I personally don't frequent bars or go to casinos, but do go to Walmart and Marshall's/Costco and Sam's, buy groceries and gas, spend in restaurants and on travel (most of airline and hotel are paid for by other).
Thanks for your comments and help.
I have an Amex Green as well. As Lexie explained, Amex will monitor your spending habits for patterns and then adjust to your use of the card, they also take into account your income and other factors (as they like to say themselves lol). You shouldn't worry initially. Let them know if, say, in 6 months you suddenly need to spend money on an unusually big purchase, that's what I usually do but otherwise you should be fine.
I was a little cautious at first about how and where I spend with my Green. But after a while I realized that I have a pretty plain vanilla spending pattern, so I just settled down and used the card as I would normally use any of my cards. Everything's been fine and I've seen no AA.
Advice like this is why I so love and trust this site. Now I await arrival of card approved last Friday.
