Frontier Airlines is pulling the plug on its service between Reno and Denver September fifth, saying the flights have never been profitable.
Frontier operates an evening flight from Denver to Reno and a morning flight back to Denver.
Krys Bart is executive director of the Reno-Tahoe Airport Authority.
She says Frontier's Denver flight never reached the necessary passenger capacity to become make money.
Today's market requires flying at 85 percent to 90 percent capacity.
The Denver runs were averaging 74 percent.
Bart says Frontier's departure probably will mean more costly tickets for passengers flying between the two cities.
