Frontier Airlines is set to re-launch flights from Sioux City’s Gateway Airport to Denver, Colorado. Back in 2008, Frontier filled Chapter-11 bankruptcy and left Sioux City, discontinuing its three flights a day to Denver International Airport. Last year, Frontier was purchased by Indigo Partners, which provides low cost air transportation. Frontier Airlines Vice President of Marketing Tryi Squyres  says the airline is returning because it believes Sioux City has a strong market for leisure and business travel.

Frontier, which is based in Denver, will be Sioux Gateway’s second airline. American Airlines flies from Sioux City to Chicago daily. The Sioux City to Denver service will be different from the flights offered six years ago. Instead of a small turboprop aircraft, Frontier will now utilize an Airbus 319.

The first Sioux City to Denver flight is scheduled for take off at 6:40 a.m. Friday.
