Buy United MileagePlus Miles With up to a 95% Bonus [Targeted]

United Airlines MileagePlus members can take advantage of a new promotion when buying miles. Offers vary depending on the number of miles you purchase, but you can purchase miles with up to a 95% bonus.

This promotion is valid through May 30, 2025, at 11:59 p.m. CT.

Let’s take a closer look at the offer.

United’s MileagePlus Buy Miles Promotion

First, you’ll need to log in to your account with your MileagePlus credentials. Then, you can determine whether this promotional offer will give you value from buying miles.

You may be targeted to score up to 95% bonus miles:

• Buy 2,000 to 4,000 miles with no bonus
• Buy 5,000 to 19,000 miles, receive a 40% bonus
• Buy 20,000 to 44,000 miles, receive a 70% bonus
• Buy 45,000 to 102,000 miles, receive a 95% bonus (~1.93 cents per mile)

If you’re targeted for the 95% bonus offer from United, you can receive 198,000 miles for a total of $3,837.75 after taxes.

Is Buying United Miles Worth It?

Let’s do the math.

If you were to max out this promotion with the best offer, instead of purchasing miles for the usual 3.5 cents per mile, you’d get them for 1.93 cents apiece.

However, note that this price is still significantly more expensive than what we value United MileagePlus miles at: 1.2 cents apiece.

Consider this one-way flight in first class with United from Chicago (ORD) to San Francisco (SFO) using miles. This would set you back 66,100 MileagePlus miles.

With the promotion, buying the necessary miles (at 1.93 cents each) would cost you about $1,276. However, the cash cost of the trip is only $665, meaning purchasing the miles is not a good use case in this scenario.

What does this mean? If you had a zero balance in your MileagePlus account, you’d still want to pay cash for this flight rather than spend far more to purchase miles.

However, there are other times when buying miles can make sense. Consider award flights to Europe that typically cost 80,000 to 88,000 miles per person in business class. You could buy those miles (at 1.98 cents each) for $1,544 to $1,698, yet the cash cost of these flights is typically over $3,000 per person. You’d save a lot by buying miles instead of buying the flight outright.

It’s usually not a great idea to buy miles just for the sake of it. If you think it can make sense in your situation, though, check out our current round-up of monthly purchase point promotions.

If you decide to buy United Airlines miles, know that United sells miles through Points.com. This means it won’t count as an airfare or travel purchase on your credit card. You should use a credit card with bonus earnings on everyday spending or a card offering a nice sign-up bonus.

Final Thoughts

United is targeting MileagePlus members with promotional rates on buying miles with up to a 95% bonus. While there are savings to be had, purchasing miles is not always a good idea unless you have a specific trip in mind and the cost of buying miles is less than the cash price of the flight you want to book — or if you need just a few more miles to grab that next great flight redemption.
