I just called up about upgrading to the Amex Plat Charge, the girl said if you upgrade from an existing Amex you don't get 75,000 points, even though the wording on the website says "for new Amex plat charge card holders". She said they have submitted feedback to Membership Rewards to get the wording changed to avoid confusion... don't know if she is talking out of her a$s or what but if so, that really removes the benefit of getting a new Plat Charge!
