I use American Express for almost everything, and unlike you, I do like getting the frequent flyer points!! I believe the card has been altered/amended (by Amex) so that I could carry a revolving credit amount if I wanted to (I don't), but until recently, you had to pay it off each month, which is a very good thing. Getting enough points for a free ticket comes quickly, and getting upgrades on a purchased ticket comes even quicker. Best wishes in finding the card that works best for you.
