Heads up, deal hunters! Frontier Airlines is running a killer promotion where you can snag miles with up to a 150% bonus. This essentially drops the price to just 1.08 cents per mile, which is the lowest we've ever seen them offered. If you've been eyeing a specific Frontier flight, or are planning on traveling with them soon, now might be the perfect time to stock up. Why does this matter to you? Well, buying miles can sometimes be cheaper than purchasing a ticket outright, especially if you find a sweet redemption deal. It's like buying discounted dollars that you can only spend on Frontier flights. But act fast, because this offer disappears on January 9, 2026. Do some quick math to see if buying miles at this price makes sense for your travel plans and happy flying!
