BELLTOWN RESIDENT Michael Komarnitsky once lost 30,000 miles in an instant. He was a consultant for Fortune 500 companies and, like George Clooney’s Up in the Air character, he logged 40 weeks a year traveling. But in the midst of juggling passwords, logins, and byzantine rules for each airline mileage program, his Delta points expired. After searching without success for a way to navigate the mileage morass, Komarnitsky decided to build one. He found a tech-savvy business partner online, and gomiles.com was born. A dashboard tracks your miles, corrals the endless deals, and helps you decide whether and when to redeem your points. And about those expiring miles? Gomiles.com guides you through a process where a 99-cent iTunes purchase restarts the clock on your account activity, giving you another year to book your free airfare. Where else can you get a ticket for a song?
