Frontier Airlines are once again offering their service to Bismarck Airport with round-trip flights to Denver International Airport.

The serviced flights will fly three days a week on Sundays, Tuesdays, and Thursdays. The flights will be scheduled during the late afternoon. In a press release, Bismarck Airport Director Greg Haug said:

We are happy to have Frontier Airlines back in Bismarck as they are a customer favorite. Frontier’s service adds another low cost option for travelers in central and western North Dakota...With Frontier back in the lineup, Bismarck Airport offers five airlines to seven destinations.

A few months back, United Airlines also announced the addition of direct flights between Bismarck and Chicago's O'Hare International Airport, which gives Bismarck Airport a second airline going to and from Chicago. American Airlines has flown from Bismarck to Chicago since October 2014.

Over the past decade, Bismarck Airport has had an overall 70 percent increase in passenger boardings.
