How do you use reward points to upgrade your airline seat?
Have you ever transferred Marriott points to United before? I haven't done this. But I did use United points to upgrade my ticket to 1st class before.
I think you can only transfer point back and forth if you are Marriott Plat. Or United Gold.
You can join rewards plus to move points around.
RewardsPlus │ Marriott Rewards │ United MileagePlus
If you have the United points already, then you can check under United's advance search for the cash + points upgrade options.
I am guessing you are talking about United, as this airline partners with Marriott.
