TL;DR

  • United MileagePlus is one of the largest and most flexible airline programs — miles open up United and roughly two dozen Star Alliance partners.
  • United uses fully dynamic award pricing — there’s no published award chart, so the mileage cost of a flight moves with cash demand.
  • Miles don’t expire (United removed expiration in August 2019), which is exactly why so many people quietly stockpile balances they never fly.
  • Independent 2026 valuations land between about 1.2 and 1.35 cents per mile (TPG 1.35¢, Frequent Miler RRV 1.3¢, NerdWallet 1.2¢); cardholders get at least 10% off award prices and elites at least 15% off.
  • Sitting on United miles you’ll never fly? You can sell your own miles for cash — same-day quote, no fees, paid before we redeem. Get a quote.

United MileagePlus is one of the largest and most flexible airline loyalty programs in the world. Miles open up flights on United and roughly two dozen Star Alliance partners, and — unlike most rewards currencies — they don’t expire. That’s great news if you fly United, but it’s also why so many people quietly accumulate hundreds of thousands of miles they never get around to using. This guide covers how MileagePlus works in 2026, how to earn, how to redeem for the most value, what United miles are actually worth — and what to do with a balance you’ll never spend.

What is United MileagePlus?

MileagePlus is United Airlines’ frequent-flyer program. You earn miles by flying United, spending on a United co-branded credit card, transferring in points from Chase and Bilt, and shopping or dining with partners. You then redeem those miles for award flights on United and across the Star Alliance network — about 25 airlines including Lufthansa, ANA, Singapore Airlines, Air Canada, Swiss, EVA Air and Turkish. One thing to understand up front: United uses fully dynamic award pricing — there is no published award chart, so the number of miles a flight costs moves with cash demand.

Miles vs. PlusPoints — they’re not the same thing. This guide is about MileagePlus miles, the currency you earn and redeem for award flights. PlusPoints are a separate upgrade currency that Premier Platinum and 1K members use to upgrade a paid or award ticket to a higher cabin. You can’t redeem PlusPoints for a free flight, and you can’t upgrade with miles the way you do with PlusPoints. When we talk about earning, redeeming, valuing or selling below, we mean miles.

Premier elite status

United has four Premier elite tiers. You qualify with a mix of Premier Qualifying Points (PQP) — roughly tied to dollars spent on flights — and Premier Qualifying Flights (PQF), or by hitting a higher PQP-only number. You also need at least four United or United Express flights. The 2026 thresholds:

Tier PQP + flights Or PQP only
Premier Silver 5,000 PQP + 15 PQF 6,000 PQP
Premier Gold 10,000 PQP + 30 PQF 12,000 PQP
Premier Platinum 15,000 PQP + 45 PQF 18,000 PQP
Premier 1K 22,000 PQP + 60 PQF 28,000 PQP

Higher status means more miles per dollar flown, better upgrade priority, free bags, lounge access perks and PlusPoints. Premier 1K is the top published tier; the invitation-only Global Services sits above it.

How to earn miles

There are four main ways to build a MileagePlus balance, and most members combine them:

You can also earn through MileagePlus Shopping, dining, hotel and car-rental partners, and by converting Marriott Bonvoy points — but flights, Chase/Bilt transfers and the co-brand cards are where almost all miles come from.

How to redeem miles

Because United prices awards dynamically, there’s no fixed chart to memorize — the cost floats with cash fares. Two helpful 2026 wrinkles: holders of a United credit card get at least 10% off the standard United award price, and Premier elites get at least 15% off. Saver-style short-haul awards can start around 5,000–7,500 miles, economy to Europe often runs in the 20,000–35,000-mile range, and United Polaris business class to Europe is commonly seen around 80,000 miles one-way — all dynamic, so your mileage will vary.

Sweet spots & redemptions worth knowing

Heads-up — a perk that’s gone: United retired the popular Excursionist Perk (a free one-way award within a region) and instant elite upgrades on August 21, 2025. If part of your strategy was building round-the-world style itineraries with a free leg, that option no longer exists — one more reason some members decide to cash out rather than wait for the program to change again.

What are United miles actually worth?

United miles are solid mid-pack airline currency. Independent 2026 valuations generally land between about 1.2 and 1.35 cents per mile: The Points Guy values them at 1.35¢, Frequent Miler’s Reasonable Redemption Value is 1.3¢ (median 1.23¢, average 1.39¢), and NerdWallet pegs them at 1.2¢. Redeeming for high-cash-fare international business or first class on a Star Alliance partner can push the value higher — sometimes 2¢ or more on a standout redemption.

Balance As cash Editorial value
50,000 miles ~$600 ~$650
100,000 miles ~$1,200 ~$1,300
250,000 miles ~$3,000 ~$3,250
500,000 miles ~$6,000 ~$6,500

But those are redemption values — and only real if you actually book a trip you wanted anyway, find saver award space on your dates, and capture a good rate. Miles don’t earn interest, dynamic pricing keeps drifting upward, and perks get cut (the Excursionist Perk being the latest). A balance you never burn is worth nothing. That gap between “paper value” and “value you’ll actually capture” is exactly why a cash-out market exists.

Frequently asked questions

Do United MileagePlus miles expire?

No. United removed mileage expiration in August 2019, so MileagePlus miles do not expire as long as your account stays open and in good standing. The only way to lose them is if the account is closed — by you, or by United for a program-rule violation. Because there’s no expiry deadline, many members hold large balances for years; if you’ll never use yours, cashing out turns idle miles into money now.

How much are United miles worth?

Independent 2026 valuations generally put United miles between about 1.2 and 1.35 cents each. The Points Guy values them at 1.35 cents, Frequent Miler at about 1.3 cents (its Reasonable Redemption Value), and NerdWallet at 1.2 cents. International business or first class on Star Alliance partners can be worth more — but only if you actually book the flight.

What’s the difference between United miles and PlusPoints?

They’re two separate currencies. Miles are what you earn and redeem for award flights on United and Star Alliance partners — and what Cash For My Miles buys. PlusPoints are a Premier Platinum/1K upgrade currency used only to upgrade an existing ticket to a higher cabin; you can’t book a free flight with PlusPoints.
