25% Bonus When You Convert Marriott Points Into United Miles

Since 2013, Marriott Rewards and United MileagePlus have had a partnership, called RewardsPlus. This arrangement extends special benefits to elite members of both programs, and also offers bonus points when converting points between programs.


Through this partnership you get:

  • A 20% discount when you convert Marriott Rewards points into United MileagePlus miles
  • A 10% mileage bonus when you choose United MileagePlus for your Hotel + Air Package
  • United MileagePlus Gold members and above receive Marriott Rewards Gold status
  • Marriott Rewards Platinum members receive United MileagePlus Silver status

Marriott offering bonus miles for points conversions

Marriott Rewards and United MileagePlus are offering bonus points when you convert Marriott Rewards points into United MileagePlus miles through March 31, 2016. Through this promotion you can earn 25% more United miles, up to a maximum of 25,000 bonus MileagePlus miles.



Registration is required, and bonus miles should post by April 30, 2016.

This promotion is valid for both points to miles conversions, as well as for Hotel + Air Packages. Before I analyze the promotion, let me say that I value two Marriott Rewards points at roughly one MileagePlus mile.

Marriott points to miles conversions

Ordinarily Marriott Rewards points convert into United MileagePlus miles at the following rate:


As you can see, if you convert 112,000 points into miles you’d receive 50,000 MileagePlus miles, and through this promotion you’d receive a further 25% bonus. That’s a total of 62,500 miles for 112,000 Marriott Rewards points.

That’s a pretty good deal, since you’re getting one United mile per ~1.8 Marriott Rewards points, which is better than my 1:2 valuation.

So I’d say that’s a moderately good deal.

Marriott Hotel + Air Packages

Ordinarily Marriott Rewards points can be redeemed for Hotel + Air Packages at the following rates:


With this promotion you can get a further 25% bonus on points conversions.

Marriott’s Hotel + Air Packages are already one of the best uses of Marriott Rewards points, as you get a fixed number of free nights plus a set number of miles. For example, you can redeem 390,000 Marriott Rewards points for seven nights at one of their Category 9 (top) properties, plus 132,000 United MileagePlus miles.

Through this promotion you’d receive a total of 157,000 MileagePlus miles (since the bonus is capped at 25,000 bonus miles). At a 1:2 valuation, that means those 157,000 United miles are worth 314,000 Marriott points. That means you’re basically redeeming 76,000 points for seven free nights at a Category 9 property, which is an exceptional value.

Keep in mind these packages are significantly less expensive for lower end properties. For example, you can redeem for seven nights at a Category 1-5 properties, plus 132,000 miles, for 270,000 points. You’d get a total of 157,000 United miles, which I consider to be worth 314,000 Marriott points, which is more than the package itself costs.

Perhaps the one hindrance to truly maximizing this promotion is that many people don’t want to stay in one hotel for seven nights. Even if you only stay for a few nights, you can come out way ahead by taking advantage of this promotion.

Bottom line

Marriott Rewards Hotel + Air Packages are already one of the best uses of Marriott Rewards points, and United is one of the best partners for that, thanks to their partnership. This bonus makes that even more rewarding. If you value United miles and have a large balance of Marriott points, I’d certainly consider taking advantage of this offer.

(Tip of the hat to Laura)


  1. Lucky. Don’t you see the high value of Marriott points. For 300,00 Marriott points you can get 157,000 UA miles PLUS 7 nights in a category 6 (pretty easy to find great 6s in Asia). Considering you earn 15 points per dollar as a top elite (plus some decent quarterly promos ), why do people think Marriott rewards sucks so bad. I mean 7.5 airline miles per dollar for your hotel stays (if they were 2:1) is Best in the business… By a looooong shot. Hyatt is less Than half that, Starwood is 3 points per dollar Starwood card adds 2 to that, plus the 25% bonus, still not 7.5. Marriott rewards is generally the best way to convert to airlines and they add in those aweso 7 nighters !!

  2. @Ryan
    Most bleisure people don’t have 7nighter opportunities. As for me, my usual vacation tops at 3-4 nights, so these are strictly useless to me.

  3. Right. But the miles alone are worth it alone They will give u 45000 points back if you don’t want the cert

  4. I converted some and the confirming email says that the award certificate is “Valid through: Tuesday, February 28, 2017”. Do these miles have normal UAL expiration rules or something special?

    Also while the registration page mentions the 25% bonus, the actual order shows regular (does not show the bonus). I am hoping the bonus points still post without a problem. I have screen freezes in case.

  5. Is it correct to say that you need to select the hotel that you are going to stay at within a one year period, and that you have a further year to stay? I think once you select the hotel and the dates, you are stuck with it — is that correct?

    Is this a bonus that has been available in March the last couple of years?

    Thank you

  6. I converted one day before register on Milelageplus. The order on Marriott hasn’t been processed. Would it be possible to get the bonus miles? It says 6 weeks to post.

  7. Does one has to stay 7 consecutive nights at one property (for 7 night package) or can it be broken into 2 or 3 nights stays at different properties at different times?

  8. so if I’m not an elite marriott member but will soon be getting alot of Marriott points due to my daughter’s upcoming wedding at marriott, is it still worth getting the new marriott card with promotion tht gives me the 5x spend at marriott? I would then like to transfer those points to Star Alliance or United? Wahtis the actual ratio of transfer?

  9. @sally kramer

    Get the Marriott card, it’s a no-brainer since you get a free night for the annual fee, plus the multiplier on Marriott spend, plus the “automatic silver” you’d get to get a bonus on Marriott spend as a Marriott elite. I paid for my wedding on the Marriott card, those points pretty much took care of the week in Cancun 🙂

    Congratulations on your daughters upcoming nuptials. Be sure to call each hotel individually they will be at for the honeymoon, we had champagne and a dessert on each of the 4 hotels we hit during our honeymoon (and we repeat “special request” each year for our anniversary night we use with the card’s free night and are always rewarded, these freebies are great, and I assume they are helped because we keep our Marriott elite status each year).

    For the transfer, I’ve never done it – cannot speak to it.

    Oh – and at this point – i’m Marriott Platinum for Life x 2 (points and nights) – just waiting for them to acknowledge you can earn that twice over, and plan to hit x 3 before I’m 40.

  10. I just did a hotel + miles redemption, transferring 132k miles to United, and the miles posted overnight. Unfortunately, the 25% (25,000, due to the cap), did not post. United is telling me that it is Marriott’s problem, and Marriott is telling me that it is United’s problem. Does anyone have any wisdom that may be able to help?
