Hey AwardTrailblazers! United's rolling out another round of their "Mile Play" promotion, and you know what that means – free miles! Until December 22nd, United's giving select MileagePlus members personalized challenges. Complete these tasks (think flying certain routes or spending a specific amount) and you'll rack up bonus miles. Why does this matter? Well, free miles are always a win, right? Think of it as a little holiday gift from United. These miles can help you top up your account for an award flight, or even just give you a nice boost toward your next vacation. Head over to your United account ASAP to see what challenges they've assigned you – some people are reporting offers up to 14,000 bonus miles! Don't leave those miles on the table!
