I am a Platinum Premier member with 185 room nights in 2102, 1841 total home nights in the program and currently have 1.3M points in my account.
I was saving them to transfer to Delta airline miles to use them for business class travel to visit my daughter that is serving in the Peace Corp in Madagascar. I can't seem to find that option on the Use Miles section of the rewards site. Did the program change? Please tell me that's not the case!!!
As you can tell, I'm a very, very loyaly customer and hope that things haven't changed to make my point WAY less valuable to me!
Looks like there are a couple of ways to go. In Marriott Rewards...click on "How to Use Points"...then click on "Travel and Unwind"... then click "Air Miles"...You'll find a table, that includes Delta, that shows the conversion rate. I'm not sure if there is a maximum, but I'll bet a call to the Rewards people will get it figured out.
Another option is the Travel Packages. tker has a tremendous blog, Maximizing Marriott Rewards Travel Packages: See the World.
This blog takes you through all the options with travel packages, including how to use the air miles separate from the hotel stay. These Travel Packages appear to maximize the point value transfer rate. This tker is the boss for these deals. He's very helpful
