Heads up, deal hunters! Frontier Airlines is running a Black Friday promotion that could seriously boost your mileage balance. Until December 1st, 2025, you can score a 100% bonus when you buy Frontier miles. That basically halves the cost, bringing it down to a cool 1.34 cents per mile. Why should you care? Well, if you fly Frontier even occasionally, this could be a cheap way to snag some award flights down the road. It's essentially like buying discounted tickets in advance. Think about upcoming holidays, spring break, or even just a quick weekend getaway. Of course, you'll want to do the math to see if it makes sense for your specific travel plans. But at this price, it's worth a look, especially if you have a particular Frontier route in mind. Just remember, this offer disappears faster than the Thanksgiving leftovers, so don't wait too long to decide!
