Jackson, WY – Frontier Airlines on Monday announced that it will expand on its existing annual summer seasonal nonstop service between Denver, Colo., and Jackson Hole, Wyo., with the addition of a ski season schedule beginning Feb. 13, 2013.

The Denver-based carrier will operate two weekly flights through April 7, 2013. Frontier’s summer season service in Jackson Hole will resume May 2013. Introductory fares as low as $99 each way are available only at FlyFrontier.com through Nov. 18, 2012.

“Our customers have thoroughly enjoyed our low fares and convenient service into Jackson Hole during the peak summer months and we’re thrilled to bring them that same low fare access to Jackson Hole’s famous ski slopes this winter,” said Daniel Shurz, Frontier’s senior vice president, commercial.

Frontier’s Jackson flights will be aboard the airline’s 138-seat Airbus 319 jet aircraft, which will depart Denver at 12:25 p.m. on Wednesdays and Sundays, arriving in Jackson at 1:55 p.m. They’ll then turn around, departing Jackson at 2:35 p.m. and arriving back in Denver at 4:05 p.m. for connections to airports across the U.S.

In addition to the new service aboard Frontier, three other airlines — American, Delta and United — offer service into Jackson Hole. Other new service this winter will be provided by United Airlines from Newark and San Francisco, as well as by Delta Air Lines from Minneapolis.
