JetSmarter is an app that lets you book a private jet. It may not sound that revolutionary, until you find out that you can make a spur-of-the-moment booking with the app and jet-set to Rome or Paris or wherever it is that you want to go and be on the plane in just a couple hours. None of the old hassles of private flight booking are an issue with this app.

JetSmarter works with air travel companies to get you a private flight in a matter of hours no matter where your desired destination is. The price of the flight is, of course, dependent on where you want to fly.

The Empty Legs feature is particularly noteworthy, especially for frugal jet-setters. You can browse jets traveling empty between two destinations and realize big savings if you hop on one of them.
