How to Buy United MileagePlus Miles (2026)

Can you buy United MileagePlus miles in 2026?

Yes, you can buy United MileagePlus miles in 2026 through four routes: purchase them directly from United, transfer transferable points from Chase Ultimate Rewards or Bilt at 1:1, convert Marriott Bonvoy points at 3:1, or buy United miles below airline prices on a marketplace like MileMarketplace. United is a Star Alliance carrier with one of the deepest partner networks in the world, so MileagePlus miles unlock award seats on Lufthansa, SWISS, ANA, EVA Air, Air Canada, and dozens of other airlines.

Buying United miles directly is expensive at roughly 3.76 cents per mile, while the average redemption is worth only about 1.35 cents per mile (The Points Guy, June 2026). That gap is exactly why many travelers buy United miles below the airline's own price instead. On MileMarketplace you can buy United MileagePlus miles below United's rate, and our team can book the award ticket in your name at the miles price, so no account transfers are needed.

How much do United MileagePlus miles cost in 2026?

United MileagePlus miles cost about 3.76 cents each when you buy them directly from United in 2026, which works out to roughly $376 per 10,000 miles (WalletHub, 2026). The minimum purchase is 2,000 miles for about $75, and you can then buy in 1,000-mile increments. United also caps direct purchases at 50,000 miles every 90 days and 200,000 miles per calendar year.

United periodically runs a buy-miles promotion with up to a 100% bonus, which drops the effective cost to about 1.88 cents per mile (AwardWallet, June 2026); the most recent promotion ran through June 24, 2026 and capped bonus-eligible purchases at 50,000 miles. Even at the promo rate, buying United miles only makes sense when you have a specific high-value redemption lined up, because the standard 3.76-cent direct price is nearly triple United's average redemption value.

How does buying United miles compare to transferring or using a marketplace?

Buying United miles directly from United is the most expensive route at about 3.76 cents per mile; transferring from Chase or Bilt at 1:1 is effectively free if you already hold those points; and buying United MileagePlus miles on a marketplace lets you pay below United's published rate. The table below compares the three acquisition routes so you can pick the cheapest source for the exact number of miles your award needs.

Which credit card points transfer to United MileagePlus in 2026?

Chase Ultimate Rewards and Bilt Rewards both transfer to United MileagePlus at a 1:1 ratio in 2026, and Marriott Bonvoy transfers at 3:1 with a 10,000-mile bonus for every 60,000 points moved (AwardWallet, 2026). Critically, United is NOT a transfer partner of American Express Membership Rewards, Citi ThankYou, or Capital One, which sets it apart from most Star Alliance programs.

• Chase Ultimate Rewards: 1:1, the most popular and flexible route into United miles.
• Bilt Rewards: 1:1, earned through rent payments and everyday spend.
• Marriott Bonvoy: 3:1 base, plus a 10,000-mile bonus per 60,000 points (effectively 70,000 miles per 180,000 points).
• Not available: Amex Membership Rewards, Citi ThankYou, and Capital One miles do not transfer to United.

Do United MileagePlus miles expire?

No, United MileagePlus miles do not expire as long as your account remains open and in good standing; United removed mileage expiration entirely back in August 2019 and that policy still holds in 2026 (NerdWallet, 2026). There is no activity requirement, so you face zero timing pressure to redeem a balance of United miles.

The one caveat is that United miles can still be forfeited if United closes your account for a program-rules violation, or if you voluntarily close the account before redeeming. Because United miles never expire on their own, it is safe to acquire United MileagePlus miles slightly ahead of a trip and hold them until award space opens up.

What are the best United MileagePlus sweet spots in 2026?

The best United MileagePlus sweet spots in 2026 are Star Alliance partner business and first class, where United quietly cut several award prices. Partner business class to Europe on Lufthansa, SWISS, Austrian, and TAP Air Portugal dropped from 88,000 to 80,000 miles each way for United cardholders, and transpacific business class on ANA and EVA Air fell from 110,000 to 100,000 miles each way (Roame, 2026).

• Partner business class to Europe: ~80,000 miles each way for cardholders (88,000 without a United card).
• Transpacific business class on ANA or EVA Air: ~100,000 miles each way, down from 110,000.
• United-operated Polaris business to Europe: from 60,000 miles each way at saver levels.
• No fuel surcharges on United-operated awards; partner awards add only taxes and fees.
• No close-in booking fees, so last-minute United awards stay affordable.
• Cardholder and elite discounts: United now offers at least 10% off awards to cardholders and 15%+ to elites (effective April 2026).

Is the United Excursionist Perk still available in 2026?

No, the United Excursionist Perk is no longer available in 2026. United eliminated the Excursionist Perk on August 21, 2025 for all new bookings and any changes to existing bookings (The Points Guy, 2025). Older guides still tout it as a uniquely valuable feature, but it has been discontinued, so do not plan a 2026 United itinerary around a free embedded one-way.

Before its elimination, the Excursionist Perk let you add a free one-way award within a round-trip MileagePlus itinerary as long as the segments stayed within defined regions. In 2026, every United award leg is priced under United's standard dynamic structure instead, so the value now comes from partner premium-cabin sweet spots and from acquiring your United MileagePlus miles cheaply rather than from any free-leg trick.

How does United dynamic award pricing work?

United MileagePlus uses dynamic award pricing with no published award chart for United-operated flights, meaning the miles needed for a United seat fluctuate with cash demand and date. United-operated Polaris business to Europe starts around 60,000 miles each way at saver levels but can climb well beyond that on peak dates (The Points Guy, 2026).

Partner awards on Star Alliance carriers are largely fixed in price (for example, ~80,000 miles for partner business to Europe), which makes United partner redemptions more predictable than United's own metal. Because United dynamic pricing varies so much, always confirm the exact miles and the specific seat on a tool like PointsYeah or seats.aero before you acquire any miles, then buy only the amount that booking requires.

How much can you save buying United miles below airline price?

The savings from buying United miles below airline price come from two gaps at once: United charges about 3.76 cents to sell you a mile, yet each mile is worth roughly 1.35 cents in redemption, and the underlying cash fare for premium cabins is far higher still. The worked example above shows how a buyer can turn a ~$4,000 cash Polaris fare into a miles redemption that costs a fraction of that.

Because United dynamic pricing and partner award levels move, the exact dollar saving on any given route depends on the day you book. The reliable part is the structure: acquire United MileagePlus miles cheaply, redeem them for a premium cabin that would otherwise cost thousands in cash, and pocket the difference. You can buy United miles below United's price and have our team book the award so you never touch a transfer or a points balance yourself.

Is it safe and legal to buy United MileagePlus miles?

Buying United miles directly from United and transferring points from Chase, Bilt, or Marriott are fully within United's rules. United's program terms, like most airline programs, restrict members from transferring their own miles to third parties, which makes the third-party side a grey area; for a fuller breakdown see where to buy airline miles safely.

When you buy United MileagePlus miles on MileMarketplace, you are buying miles below the airline's price and our team books the award ticket in your name at the miles price, so no risky account transfers happen on your side. To compare routes and protections, see where to buy airline miles safely. Always confirm the exact award space and miles count before you commit, because United's dynamic pricing can change the number of miles a seat needs from one search to the next.

When is buying United miles worth it versus paying cash?

Buying United miles is worth it when your all-in cost per mile is well below the value you will extract, which in 2026 means redeeming for partner or United premium cabins rather than cheap economy. Since United's average redemption is about 1.35 cents per mile (The Points Guy, June 2026), paying United's 3.76-cent direct rate destroys value, while buying United miles below airline price flips the math in your favor.

For cheap cash economy tickets, paying cash is almost always smarter than burning miles, and you still earn miles on the paid fare. For a lie-flat business or first seat that costs thousands in cash, buying United MileagePlus miles cheaply and redeeming them can save four figures per ticket. To sanity-check any individual deal, weigh the cents-per-mile you pay against the cash fare, and read are airline miles worth buying and how much are airline miles worth before you commit.
