Crave a window seat? Then pay a passenger with a better seat to swap seats with you. That’s the core message behind the new app Seateroo which launched this month. Free to use, the app makes money by take a 15% cut out of each transaction. The app is available through the Apple Store and only available in the United States for the moment.
