Heads up, United flyers! If you're eyeing a sweet award flight but your MileagePlus account is looking a little bare, United's offering a limited-time sale on buying miles. Until November 25, 2025, you could snag a bonus of up to 100% when you purchase miles, potentially dropping the price to just 1.88 cents per mile. Now, should you jump on this? That depends! Generally, buying miles isn't the best deal unless you have a specific redemption in mind and this sale brings the cost down enough to make it worthwhile. Think of it like this: if you're just a few thousand miles short of that dream trip to Hawaii, and buying those miles at this price gets you there, then it could be a smart move. Before you buy, always do the math. Check how much the award flight would cost in cash versus the cost of buying the miles needed. Factor in any taxes or fees you'd have to pay on the award ticket too. If the numbers add up in your favor, this could be a great way to make that trip a reality!
