Several airlines and hotel loyalty programs regularly launch bonus transfer offers that allow users to get more value from their air miles or reward points. Under the latest promotion, United Airlines MileagePlus members can earn 25% bonus miles on eligible hotel points-to-miles transfers made between 1st June 2026 and 30th June 2026. Members can earn up to a maximum of 25,000 bonus miles through this offer.
To become eligible, members must first register for the promotion during the offer period. After registration, any eligible hotel points transferred into MileagePlus miles from participating hotel loyalty programs will qualify for the additional bonus miles.
The bonus miles will be calculated based on the total miles earned through eligible transfers during the promotional period. However, for transfers from Marriott Bonvoy, the regular 10,000-mile bonus offered on every 60,000 Bonvoy points transferred will not be considered while calculating the additional 25% promotional bonus.
In simple terms, the 25% bonus will only apply to the base MileagePlus miles received from the transfer.
To earn the full 25,000 bonus miles under this promotion, members would need to transfer hotel points equivalent to 100,000 eligible MileagePlus miles during the offer period. United Airlines has also notified that bonus miles will be credited by September 2026.
How Many Marriott Bonvoy Points Need to Be Transferred to Earn the Complete 25% Bonus?
To Earn the Complete 25,000 Bonus Miles Under This Promotion, You Would Need to Transfer 300,000 Marriott Bonvoy Points to United Airlines MileagePlus.
Here’s Why:
- Marriott Bonvoy Transfers at a 3:1 Ratio
- 300,000 Bonvoy Points = 100,000 Base MileagePlus Miles
- The Promotional Bonus is Calculated Only on These Base Miles
- 25% of 100,000 Miles = 25,000 Bonus Miles
Additionally, Since United MileagePlus Members Get an Extra 10,000 Miles for Every 60,000 Marriott Points Transferred, You Would Also Receive Another 50,000 Bonus Miles Separately From Marriott’s Standard Offer.
By transferring 300,000 Marriott Bonvoy points to United Airlines MileagePlus, members would receive 100,000 base MileagePlus miles at the standard 3:1 transfer ratio. In addition, Marriott’s special United partnership adds another 50,000 bonus miles, while the ongoing 25% promotion would further provide 25,000 bonus miles.
This brings the total to 175,000 MileagePlus miles, which is generally good enough for an Economy Class redemption to the USA and, in some cases, even Business Class saver redemptions depending on route and availability.
Bottom Line
This promotion can be useful for travelers who have unused hotel points and are planning future flight redemptions through the MileagePlus program. However, cardholders should plan their redemptions carefully to ensure they get the best possible value from both their hotel points and airline miles.
