United MileagePlus Offers Up to 95% Bonus on Purchased Miles

United MileagePlus is running a promotion that allows members to purchase miles with a tiered bonus, ranging from 95% to no bonus at all. The offer is valid until August 20, 2026, at 11:59 PM Central Time. To get the maximum bonus of 95%, you need to purchase 20,000 or more miles in one transaction, which will cost around USD Cents 1.92 per mile.

Unlike other airline loyalty programs, United MileagePlus does not pass on fuel surcharges to its customers and also offers the benefit of not expiring miles. This means that members can redeem their miles on Star Alliance member airlines without worrying about them expiring.

When buying miles with this promotion, it's essential to consider using a credit card that offers extra points on international spending or reduced foreign exchange conversion rates. The Axis Olympus, Axis Reserve, and American Express Platinum Charge Card are some options to explore.
