Earn up to 100% Back on Bonus Miles During the United MileagePlus Flash Sale

The sale ends tonight, so don't wait.

Advertiser Disclosure: At Slickdeals, we work hard to find the best deals. Some products in our articles are from partners who may provide us with compensation, but this doesn’t change our opinions.

Calling all MileagePlus members: United is running a flash sale through 11:59 p.m. CT today, December 19th.

You can buy miles for as little as $1.88 each during the sale and earn up to 100% bonus miles on your purchase. The price per mile and percentage of mileage bonus depends on the total amount purchased, so make sure to read the fine print. If you’re looking to redeem an award but are a little short on the required mileage, this is a great opportunity.

If you’re not already a MileagePlus member, the program is free to join. Once you sign up, you can earn miles on travel and other everyday purchases. United also offers bonus miles for getting its Explorer credit card. However, we don’t recommend applying just to get the bonus miles unless it makes sense for you; for example, if you already travel frequently.

You don’t need to be a cardholder, only a MileagePlus member, to buy United miles through this flash sale. However, buying airline miles only makes sense for certain travelers and especially for specific types of award redemption, such as international flights and business or first-class seats.

A person who already has a lot of award miles stockpiled and just needs a small amount more to qualify for an award flight to Asia, Africa, or the Middle East, or wants to get a first-class seat to Hawaii from the East Coast, for example, could come out way ahead in this United MileagePlus Sale. It’s definitely worth checking out if you fall into that category.
