According to a survey conducted by GO Airport Express, a Chicago-based ground transportation provider, a whopping 88 percent apply miles toward ticket purchases. The company, which provides airport shuttles to and from O'Hare International Airport and Midway Airports, polled travelers nationwide: more than 380 people responded. Just six percent of participants reported using their miles toward hotels. Four percent use them for products and one percent donate them to charity.
