Great Lakes Airlines is dropping its service to Gillette Campbell County Airport on May 17.
Great Lakes had provided two round trips per day between Gillette and Denver on its 19-seat aircraft.
The departure marks the end of a 13-year relationship between the airport and the Cheyenne-based airline, which for years offered the only flights to and from Gillette.
Airport Director Jay Lundell tells the Gillette News Record (http://bit.ly/IBfUr2 ) that competition from new airlines and opportunities in other cities made it more profitable for Great Lakes to look for business elsewhere.
Lundell says SkyWest Airlines could help to fill the void.
SkyWest now runs three daily round-trip flights between Denver in Gillette on a 30-seat plane.
