log into Marriott.com, go to your profile and it will say combine your accounts....start the process and see what happens. Read my instructions and steps above as to what it asks for and displays during the combine steps as it doesn’t show lifetime nights until after you’ve completed the steps.

Logging back in today, I now see all my past activity including both past spg and Marriott stays. Yesterday I couldn’t see past SPG stays.

All my data is is still displaying correctly (nights, points, status etc)

This link now redirects to Marriott but starts off at the old SPG site and let me log in just fine this morning.

FYI, lifetime status is a bit hard to see under your account overview. It will first tell you in various places your current status (not including the Lifetime flag) ie Platinum Elite, then farther down the page (you need to look for it) it says you are Lifetime Platinum Elite and for me it also says up next (Jan) Lifetime Premier Elite
