Buy MileagePlus miles
There are four realistic ways to add MileagePlus miles to an account: buy direct from United Airlines, earn them, transfer eligible partner points, or ask us for an independent quote. Buyers often want MileagePlus miles because Star Alliance partner space is showing on a specific date and their own balance falls short.
How to buy MileagePlus miles
| Option | How it works | Advantages | Limitations |
|---|---|---|---|
| Buy direct from United Airlines | Purchase through the airline's own official Buy Miles page where it is offered. | Straightforward, within programme terms, sometimes bonused. | Retail pricing, annual purchase caps, and price varies with promotions. |
| Earn through flying and partners | Miles are earned on United and Star Alliance flights, co-brand cards, the MileagePlus shopping portal, hotel and car partners, and periodic promotions. | No purchase cost, and flights also earn status credit. | Slow if you need a specific balance for a booking soon. |
| Transfer eligible partner points | United supports buying, gifting and transferring miles for a fee, and Chase Ultimate Rewards lists MileagePlus as a transfer partner. | Can be cheaper than buying, and ratios are sometimes bonused. | Transfers are usually irreversible and are governed by both providers' terms. |
| Request a MilesQuote quote | Tell us the shortfall and the award you are trying to book; we review it and reply with an indicative figure or an honest no. | Independent comparison against the direct price, no published rate to talk you into. | No guaranteed price, no guaranteed availability, and programme terms still govern your account. |
How much MileagePlus miles cost
United sells miles directly on united.com, sometimes with promotional bonuses on larger purchases. That direct price is your benchmark. Any third-party figure — ours included — should be compared against it with taxes and carrier-imposed surcharges included, not against the headline award price alone.
Run the arithmetic before committing with the miles vs cash calculator, which compares the full award total against the cash fare.
How MileagePlus awards are priced
Redemptions include United flights, Star Alliance partner awards, Excursionist Perk itineraries on round trips, and upgrade awards.
With dynamic pricing on United metal, the honest way to value MileagePlus miles is against the exact itinerary and cash fare in front of you.
When buying miles makes sense
- You have already found award space on your exact dates.
- You are short by a modest amount and only need to buy the shortfall.
- The award is a premium cabin where the cash fare is several times the award cost.
- The all-in award total is clearly below the cash fare, not marginally below it.
When buying miles usually does not make sense
- You are buying speculatively, with no confirmed award availability.
- The saving is under roughly ten per cent — cash keeps flexibility and earning.
- Surcharges absorb most of the fare you were trying to avoid.
- The redemption is short-haul economy against an already-cheap fare.

Current promotions
We do not publish promotion claims. Airline purchase bonuses appear and expire quickly, so check United Airlines's official purchase page for what is live today and treat any third-party promotion table as advertising.
Before you buy
- Confirm award availability on your exact dates before buying any miles.
- Compare any quote against United Airlines's own purchase price, including promotions.
- Include taxes and carrier-imposed surcharges in the total cost.
- Read United Airlines's programme terms — they govern your account, not us.
