The United MileagePlus program is running a 25% bonus on hotel-to-miles transfers through June 30, 2026, and while it won't make sense for most people, there's one specific scenario where the math actually works in your favor.

Registration is required. You must sign up at promo.united.com/offers/p2m before 11:59 PM ET on June 30, 2026. All transfers must also be completed by that same deadline. The promotion caps out at 25,000 bonus miles per member, no matter how many hotel currencies you convert.

Who Should Pay Attention

Hotel-to-airline transfers are almost always a bad deal. That hasn't changed here, and a 25% bonus doesn't fix a broken exchange rate. But two groups of people should take a closer look.

If you have orphaned hotel points, this is worth considering. A small balance sitting in a program you never use has effectively zero value. Converting those points into MileagePlus miles at a slightly boosted rate is better than watching them expire. Don't expect great value per point, but some value beats none.

If you have Marriott Bonvoy points and no great redemption in sight, the numbers can actually work out favorably. Here's why: United has a special relationship with Bonvoy that gives you 10,000 bonus miles every time you transfer 60,000 Bonvoy points (instead of the standard 5,000 bonus miles other airline programs offer). Layer the current 25% promotion on top of that, and a 60,000-point Bonvoy transfer produces 35,000 United miles: 20,000 base miles, a 5,000-mile bump from the 25% bonus, and the 10,000-mile Bonvoy sweetener.

Using standard valuations of roughly 0.6 cents per Bonvoy point and 1.2 cents per United mile, you'd be converting $360 worth of hotel points into $420 worth of airline miles. That's a real gain. If you're actively stacking Bonvoy points with a co-branded card like the Marriott Bonvoy Boundless — or sitting on a balance from a recent stay — it's worth running the numbers against any hotel redemptions you have in mind. Our Marriott Bonvoy 2025 program changes guide breaks down how recent devaluations affect your points' hotel value, which is the key input for deciding whether a transfer makes sense.

One important note from the terms: the 10,000-mile Bonvoy sweetener is excluded from the 25% bonus calculation. United applies the bonus to the base transfer amount only, so the math above already accounts for that correctly.

Current Transfer Rates From Hotel Partners

These are the standard exchange rates before the 25% bonus is applied. For more context on how these stack up, our complete guide to transferring hotel points to airlines covers the full landscape.

• Marriott Bonvoy – 3 points : 1 mile (plus 10,000-mile bonus per 60K transferred)
• World of Hyatt – 5 points : 2 miles
• Hilton Honors – 10 points : 1 mile
• IHG One Rewards – 5 points : 1 mile
• Choice Privileges – 5 points : 1 mile
• Accor Live Limitless – 2 points : 1 mile
• Shangri-La Circle – 1 point : 1 mile (2,500-point minimum)
• Wyndham Rewards – variable (6,000 points yields 1,200 miles at base rate)

Hilton, IHG, Choice, and Wyndham transfers remain poor deals even with the bonus. The exchange rates are simply too unfavorable for a 25% uplift to rescue them.

Want More United Miles Without the Transfer Math?

If this promotion got you thinking about building a larger MileagePlus balance, the more reliable path is earning miles directly. The United Quest Card earns 3x miles on United purchases and 2x on all other travel and dining, with no need to convert from a hotel currency. You can also transfer Chase Ultimate Rewards points to MileagePlus at a 1:1 ratio, which is a far more efficient way to stack miles than most hotel conversions.

The Bottom Line

Register, run the math on whatever hotel balances you're holding, and only pull the trigger if you're sitting on Bonvoy points with no clear hotel redemption target or have small orphaned balances you'd otherwise lose. For everyone else, this is a promotion worth skipping.
