Wyoming's Jackson Hole Mountain Resort is offering a fourth airline ticket free this winter. Their Fourth Flies Free program provides a fourth air ticket free for up to $500 travel credit for the 2009-10 ski season.

The Fourth Flies Free credit is valid on any of the three major U.S. carriers that fly daily to Jackson Hole. Flights arrive nonstop from eight cities, including Chicago, Dallas, Denver, Minneapolis, and Salt Lake City.

"The 4th Flies Free program is an incredible plus for our customers," states Jackson Hole Mountain Resort Brand Director, Anna Olson. "With the launch of the new tram, our legendary "cowboy" powder, personalized customer service, and a free airline ticket, we're giving potential visitors every reason to make Jackson Hole their first-choice winter destination this year."

The Fourth Flies Free program is available to those visitors who purchase at least five nights of lodging and a three-day lift ticket to Jackson Hole Mountain Resort for each traveler. The program is limited to eight people per group.

The program is available for new reservations only, but it is valid all season long. Reservations, however, must be booked by Jan. 1, 2010.

Blackout dates include the Christmas holidays. Valid dates of travel this winter for the program include Nov. 28 - Dec. 18 and Jan. 3 - April 4.
