Understanding and using frequent flyer miles to their full extent might be one of the travel world’s greatest mysteries. Milez—an airline mile calculator—is hoping to make things a little easier on your brain and your wallet.

Simply plug in your destination and which frequent flyer program you’re enrolled in, and the generator will provide how many award miles it’ll take to get you where you want to go. And no matter if where you’re going is out of the country—Milez is currently tracking 76 different programs, including both domestic and international airline brands.

Aside from helping you plan a specific trip, the site also allows you to see all a full list of their included programs and what kind of free mileage they offer based on a destination. Even more helpful (read: fun) might be the website’s suggestion engine, which shares the destinations you can visit based on your current number of miles. Time to start window (seat) shopping.
