Want to stick an extra ski trip to Jackson Hole in your spring? American Airlines has discounted the price of flights to Jackson Hole. A limited number of economy class seats have received a discount of 20-40 percent, which means you can get to and from the slopes for less.

Discounts of 20 percent are given on flights from Washington D.C., New York, Baltimore, Boston, Austin, Dallas, New Orleans, and Miami. For instance, a roundtrip flight from Washington DC to Jackson Hole now costs $463 on sale. Flights from Dallas cost $387. Those rates include taxes and fees.

Prices on flights from other destinations are seeing deeper discounts. Flights from Newark were dropped about 33 percent, and flights from Atlanta plunged by 46 percent.

In order to get the discount, flights must be purchased by Feb. 28, 2013. If traveling earlier, they must be purchased at least seven days in advance of departure or within one day of making the reservations — whichever comes first. Travel can start as early as Feb. 21.

To get the discounted rates, your return travel from Jackson Hole must be completed by April 1. Discounted flights are not available March 7-10 to Jackson Hole or March 15-17 from Jackson Hole. Some flights may require at least a two-night stay.

Reservations are required. Flights must be booked on the American Airlines website.
