The lifetime requirements were changed this week to reduce the points threshold for Marriott Lifetime status. The change has been discussed on the
MarriottRewardsInsiders.com forum by members and confirmed by Marriott Rewards representative Andrew. (No link here since you must be registered to read the MarriottRewardsInsiders website).
Years membership (12 or more)and qualifying nights are unchanged. Only the lifetime points threshold has been reduced.
You must achieve all three criteria levels for lifetime membership.
1) At least 12 years Marriott Rewards membership and achieved Silver, Gold, or Platinum elite status for one or more years.
(You can't earn lifetime platinum unless you have earned platinum elite membership at least one year in your Marriott Rewards membership. Same for Gold and Silver.)
2) Stayed at least 600 nights (Silver); 800 nights (Gold); 1,000 nights (Platinum).
3) Earned at least 1.2 million points (Silver); 1.6 million (Gold); or 2.0 million (Platinum).
Lifetime Points Threshold has been reduced. The old numbers were 1.5 million (Silver); 2.0 million (Gold); and 3.0 million points (Platinum).
