United MileagePlus to Marriott Bonvoy: 20% Transfer Bonus Until November 30
Loading article…
Until November 30, 2026, eligible members earn 20% bonus points when they transfer United MileagePlus miles to Marriott Bonvoy. The usual 1-to-1 ratio becomes 1 mile for 1.2 points. Details are on the official Marriott Bonvoy and United partnership page and in its terms and conditions.
This transfer is limited to members who hold United Premier status. If you fly United often out of Toronto, Montreal or Vancouver and have reached that status, the offer applies to you. Other MileagePlus members cannot convert miles to Marriott points.
What the United to Marriott transfer bonus includes
The United to Marriott Bonvoy transfer bonus applies to every conversion made during the offer period.
- Offer period: until November 30, 2026
- Bonus: 20% extra Marriott Bonvoy points
- Ratio with the bonus: 1,000 United miles become 1,200 Marriott Bonvoy points
- Minimum transfer: 500 MileagePlus miles per conversion
- Promotion registration: not required
The name on your MileagePlus account must match the name on your Marriott Bonvoy account, or the points will not post. An annual cap on convertible miles applies per member: check the amount shown in your MileagePlus account before a large transfer.
Who can transfer United miles to Marriott Bonvoy
Converting miles to Marriott Bonvoy points is a benefit of the RewardsPlus partnership between United and Marriott. You need to be a member of both programs and hold valid United MileagePlus Premier status.
How to make the transfer
- Go to the partnership conversion page at marriottbonvoy.unitedmileageplus.com.
- Choose the option to convert miles into points and sign in to your MileagePlus account.
- Pick the number of miles, in amounts of at least 500, then confirm.
- Check your Marriott Bonvoy balance over the following days.
Posting times can vary. Do not wait until the last minute if a specific booking depends on it.
Is this transfer worth it?
In most cases, no. By our valuations, a United MileagePlus mile is worth about 1.6 cents and a Marriott Bonvoy point about 1 cent.
- 1,000 United miles: about $16 in value
- 1,200 Marriott Bonvoy points received: about $12 in value
- Difference: about $4 lost per 1,000 miles
Even with the 20% bonus, you give up value. United miles are more useful for award flights, including on Star Alliance partners.
The transfer makes sense in one case: you are a few thousand Marriott Bonvoy points short of an award night you have already found, and your United miles have no flight planned. Topping up a balance this way costs less than buying points.
Other benefits of the United and Marriott partnership
The RewardsPlus partnership also includes status benefits and a transfer in the other direction.
- United Premier Gold members and above: Marriott Bonvoy Gold Elite status upon registration
- Marriott Bonvoy Titanium Elite and Ambassador Elite members: United MileagePlus Premier Silver status upon registration
- Marriott Bonvoy to United transfers: 3 points for 1 mile, with 10,000 bonus miles for every 60,000 points transferred
The partnership also ran cross-promotions this summer, such as the bonus points and miles offer on Marriott Bonvoy stays.
Bottom Line
If you hold United Premier status and are short on Marriott Bonvoy points for a specific booking, transfer only what you need before November 30, 2026. Otherwise, keep your United miles for flights: the conversion loses value, even with a 20% bonus.
