Here's another great opportunity to buy United miles on the cheap! The airline is once again offering a bonus when you purchase MileagePlus miles — this current promo's available today through 11:59pm CDT on Monday, August 15. If you do purchase miles during this timeframe, though, you can earn up to a 100% bonus.
This appears to be a tiered offer, with bonuses ranging from 25% to 100% depending on how many miles you buy.
Here’s how to take advantage of the promotion:
- Visit United’s Buy Miles page.
- Click on Buy Personal Miles or Give Miles (both are eligible for the bonus).
- Log in to your United MileagePlus account.
- Select the number of miles you want to buy/give and click Continue.
- Fill in the required information to finalize your purchase.
Keep in mind that the usual restrictions for purchasing United miles apply to this promotion, including the following:
- You must purchase at least 2,000 miles but can only purchase 150,000 miles per account per calendar year.
- Miles may be purchased in increments of 1,000 miles up to a maximum of 100,000 miles and in increments of 5,000 miles up to a maximum of 150,000 miles.
- Miles may take up to 48 hours to post to your account.
- Purchased or gifted miles do not count toward MileagePlus Premier status.
Should You Buy?
TPG values United miles at 1.5 cents apiece, but depending on your redemption you can definitely get more value out of these rewards. The usual cost to buy miles is ~3.76 per mile ($35 per 1,000 miles plus a tax recovery fee), and even the lowest tier of this promotion gets you a significantly lower price. Here's how the effective cost breaks down by tier:
- Buy 5,000-14,000 miles (25% bonus): 3 cents per mile
- Buy 15,000-29,000 miles (60% bonus): 2.35 cents per mile
- Buy 30,000-75,000 miles (100% bonus): 1.88 cents per mile
Clearly, you'll get a better deal if you maximize the promo by purchasing at least 30,000 miles to get the 100% bonus at an effective per-mile cost of 1.88 cents. But since earning the 100% bonus requires spending at least $1,129, this promo really only makes sense if you have a redemption in mind.
For example, these miles could come in handy for last-minute travel, such as this sample one-way from EWR to LAX for tomorrow:
Business fares start at $1,672, but a business Saver award will cost you 25,000 miles plus $5.60 in taxes and fees. If you were low on miles and wanted to book this award, you could purchase 16,000 miles (with a 9,600-mile bonus) for $602 and come out $1,070 ahead. Of course, you could also buy miles toward more aspirational redemptions like Lufthansa first class on the A380 from Europe to the US, which will cost you 110,000 miles one-way ($2,070 if your account balance is zeroed out and you take advantage of the current promotion).
Also note that buying miles isn't your only option for topping up your MileagePlus account. United is a Chase Ultimate Rewards transfer partner, so you can move points earned with the Chase Sapphire Preferred Card and the Ink Business Plus Card over to the frequent flyer program at a 1:1 ratio. You can also stock up on miles by opening the United MileagePlus Explorer Card, which is currently offering a sign-up bonus of 30,000 miles when you spend $1,000 in the first three months (check to see if you're targeted for a higher offer). This card can also open up additional award inventory (including at the Saver level), which makes it easier to put your miles to good use.
Which Card to Use?
Since United miles purchases are processed by Points.com, they're not eligible for bonus rewards with cards like the United MileagePlus Explorer Card. This means you're best off choosing a card that offers a high return on non-bonus category spending, such as the Chase Freedom Unlimited Card or the Starwood Preferred Guest Card from American Express.
Bottom Line
This promotion offers a chance to buy United miles at a relatively low price — even if you don't maximize the tiered system by purchasing at least 30,000 miles, you'll be getting a better per-mile cost than the standard offer. However, it's probably only worth taking advantage of this promo if you have a specific redemption in mind.
