Congratulations on a very thoughtful post. Thanks for, Lack of Marriott Response and Re: Loyalty Programs. Doing so prompted a look at your profile, uncovering your October 23 post, New Program Scam. This post offers a solution that I like and think it merits serious consideration.
As you point out the AAdvantage program differentiates between "original" miles and "new" miles. This approach has potential application as a solution for Marriott Reward members under several scenarios including but not limited to:
If you or anyone else has additional information about the AAdvantage approach let's discuss and vet it here. As a first step, I am particularly interested to know if the AAdvantage program underwent any legal challenges as the United Mileage Plus program.

Thanks in advance for your participation and congratulations on a very thoughtful post.
