United MileagePlus Offers Up to 45% Off Purchased Miles Until August 20, 2026
Strategically buying miles & points can represent a great deal, especially for luxury travel. United Airlines MileagePlus has just launched its newest sale on purchased miles . As usual, different members may be targeted for different offers. While I'll cover the details of this promotion, let me state that I wouldn't typically recommend taking advantage of this, as I think you're better off buying rewards with another program, like Air Canada Aeroplan or Avianca Lifemiles. They often sell points at a lower cost, and have better redemption rates (though even these programs have made some negative changes over time). The major reason to buy United MileagePlus miles is if you're looking to redeem for long haul travel in Polaris business class, where these miles leave you best positioned. Promotion on purchased United MileagePlus miles Between July 14 and August 20, 2026, United MileagePlus is offering a sale on purchased miles . Different members may be eligible for different offers — some members may be targeted for bonus offers, while other members may be targeted for discount offers. You'll want to log into your account and see what you're eligible for. Best I can tell, it looks like most members are being targeted for either a 40% or 45% discount on the purchase of miles. In order to unlock the best price, you need to purchase at least 30,000 miles in one transaction, pre-bonus.

Beyond that, I don't generally consider the MileagePlus partner award redemption rates to be that compelling. I think there are other Star Alliance programs with better redemption rates and/or program policies, including Air Canada Aeroplan and Avianca Lifemiles . Both programs often sell miles at a lower cost, and Air Canada Aeroplan also has a lucrative stopover policy .
