Constantly traveling?

Well, OneGo might be the only way to go for those constantly in flight for business.

The smartphone booking app for flights announced Monday that it's offering unlimited flights to anywhere within the United States for a flat monthly fee. How much will it cost you? Well, OneGo's offer begins at $1,500 a month, as the company aims to altogether rewrite the booking experience for flights.

A west coast plan, which encompasses 35 routes and 14 airports, starts at $1,500 per month, while the central regional plan runs at $1,950 (including 35 routes and 18 airports) and the east coast plan will cost $2,300, (covering 158 routes and 39 airports).

OneGo was able to achieve this offer by essentially consolidating airline costs into a single expense, eliminating the time-consuming hassle of comparing costs. The app's fixed monthly fee will only require its users to choose flights based on two criteria — departure time and preferred airline. Plus, they can choose their preferences for seating.

"Booking air travel is incredibly overwhelming," OneGo founder and CEO Paulius Grigas said as part of the app's announcement about its unlimited flights offer. "When you search for flights today, you are presented with so many options that make finding the best flight very difficult. When you take price out of the equation, and replace it with a flat monthly fee, you gain the freedom to fly as much as you need for your business without having to consider anything other than your flight's arrival and departure times."

The app will allow its users to book direct domestic flights using major airlines. While OneGo's offer, beginning at $1,500 per month for unlimited flights, was the announcement Monday, the company added that it would give its customers the ability to further customize via booking changes and last-minute bookings in the near future.

In addition, OneGo also plans on launching a desktop version of its app during the first half of this year.
