You can transfer Marriott Bonvoy points to United Airlines MileagePlus at a rate of 3 Marriott points to 1.1 United miles.
This is a 10% special bonus for transfers to United, because the typical rate is 3 to 1.
For example, 10,000 Marriott points convert to 3,667 United Airlines miles.
But you can score an even better deal by transferring in increments of 60,000 points, which gets you a 5,000 airline mileage bonus, which lowers the transfer rate to 2.2 Marriott points to 1 United mile.
For example, 60,000 Marriott Bonvoy points convert to 27,000 MileagePlus miles.
Typically, transfers from Marriott to United Airlines take about 7 days to complete, so be aware of this delay when booking travel.

How to Transfer Marriott Points
Transferring Marriott points to United is very easy.
First, visit Marriott’s airline transfer page and sign into your Marriott account.
After you sign in, scroll down the page and click the button that says “Transfer Points.”
