Here's hoping that other airlines introduce an app similar to the Burn the Miles app. This creative application encourages frequent fliers to become frequent exercisers. It works along with BalticMiles, a Latvian-based frequent flier program. The app challenges travelers to burn as many calories as miles flown within a 24-hour period. Those who are successful gain bonus BalticMiles that can be used for items in the duty free and flights.
The Burn the Miles app works in conjunction with sports trackers, such as Nike+, so certain types of exercise can't be monitored. Still, the idea behind the application is great, especially for businessmen and women who find themselves "unable to find the time" to exercise due to their travel schedules.
