You don’t have to take out a second mortgage to finance your family ski vacation (thanks to American Airlines), ’cause your kids will fly free to one of America’s hippest, hottest ski resorts: Vail, Beaver Creek, Breckenridge, Keystone or South Lake Tahoe.

Between Jan. 3 and Feb. 17, and again between March 29 and April 24, one child between the ages of 2 and 12 will fly roundtrip free for each paying adult on American or American Eagle flights to Denver, Reno or Vail. Hotel rates start at $152 per person with a three-night minimum stay. Get online now and book your air, hotel, car rentals and lift tickets.

Some restrictions apply: Flights must originate within the 48 contiguous states, and taxes and fees are not included.
