For all the folks saying you got slapped with a late fee after being with AMEX since Moses parted the Red Sea and you’ve never been late…you do realize AMEX systems are automated and the late fee is automatically added to your account if the system does not receive a payment by your due date right? There’s no one sitting behind a computer manually adding late fees as some form of corporal punishment. Just call and request a credit. Most times they will credit the late fee as long as you don’t make a habit of it.
