Got this announced in the mail today from Amex. It is being touted as giving you "The freedom to travel on your own terms." It provides exemptions from blackout dates and frequent flyer seat restrictions but puts someahte severe limits on the value of the tickets that it will supply. They are charging $75 to enroll if you already have a Platinum or Rewards Plus card, but I have not figured out from the fine print how much it will cost, or even if you can enroll some other Amex card.
It's no good for me because I only use my miles for international upgrades, but it might be interesting to others.
For more info it tells you to call 800-443-9251 and mention code 0209.
