Heads up, United MileagePlus members! If you're eyeing a sweet award flight but your mileage balance is looking a little sad, United is offering a bonus on purchased miles until October 18, 2025. You could score up to a 95% bonus, bringing the price down to just 1.93 cents per mile. So, should you jump on this? Well, it depends. Buying miles is rarely the absolute cheapest way to travel, but if you're just a few thousand miles short of that dream trip, or you've found a particularly good award redemption (meaning you're getting a lot of value per mile), then this sale might be worth a look. Just be sure to crunch the numbers before you buy. Figure out exactly how many miles you need and compare the cost of buying them to the cash price of the ticket. If the math checks out and you're saving money, then go for it and get closer to your next adventure!
