This Amex thing can really tank your score quickly--and confusing! DH has a Amex Platinum--his monthly charges can range from 1500- 30,000+ depending on how much he is traveling. He always pays it in full and before the due date; however, I have noticed that the reporting does not coincide with the actual payment made or balance. Additionally, the balance reported may not be current. So, in a month where he only charges 1500 his scores will go up --the next month they drop if he has a lot of activity. Keep in mind, he always pays in full (and often pays the "recent charges" which have technically not been billed. I have been tempted to dispute the balance as not being accurate-- but don't know what good that will do.
