That will be a twice-weekly service, which is estimated to bring more than $21 million to the state.

Also in July, Norwegian Air announced new nonstop service from Denver to Paris, France, with routes also servicing London’s Gatwick Airport.

Norwegian plans to have the routes to Paris begin in the spring of 2018, operating twice weekly, with prices starting as low as $229 each way.
