Frontier Airlines is launching flights from Denver to three new destinations in the western United States this month, part of its year-long push that will double the number of non-stop routes the locally headquartered company will fly nationwide.

The airline will begin service out of Denver International Airport to Oklahoma City, Palm Springs and Reno by Nov. 21, with the Palms Springs route being flown seasonally and the other two routes becoming year-round additions.
