Via press release:
The Bismarck Airport has been notified by Frontier Airlines that they will suspend service between Bismarck Airport and Denver International Airport starting January 5,
2015. Frontier Airlines is currently evaluating a return to Bismarck on a seasonal basis.
“The decision made by Frontier is unfortunate for Bismarck and the region, however we are optimistic that Bismarck’s market is strong enough to regain seasonal service during peak travel times,” said Airport Manager, Greg Haug. “We will provide more information regarding the potential of Frontier returning on a seasonal basis as information becomes available.”
Passengers with travel booked after January 5, 2015 will be contacted by Frontier Airlines and offered a full refund.
