I've had the premium car rental protection on my account for years - the higher one @ $15.25 per rental. Usually it posts to my AmEx the day after the car rental charge posts after turning in the rental and closing the contract. However, I just realized that my rental that concluded on June 12 has not had a corresponding charge for the premium rental protection. I've reconfirmed that my account is still enrolled.

Should this be of any concern? I guess for this specific rental it's a moot point since the rental was closed out with no issues, but what if there was an issue? If AmEx hasn't processed the charge, is it enough that I can show a screen shot that my card is enrolled?
