So, I have a new AMEX. Canceled my wife's. I got a Plat for the increased travel benefits.

I called tonight to change the CC my current reservations are guaranteed with. (Updating the profile only impacts future reservations.)

The plat. agent was very helpful. My wife logged in to my Marriott account and asked me what happened to all of my points. What?!!? I haven't used them.

The three rewards reservations I have (including a week at the C-E in May) all pulled the points again. (Although the C-E original reservation is a TP.)

Marriott fixed it and returned all points.Took about 45 mins on the phone.

I was missing about 200k+ points!
