[5] During peak seasons of summer and winter, Jackson Hole has nonstop airline service from up to 15 destinations throughout the United States.[7] The original Frontier Airlines was the first carrier to serve Jackson Hole, starting in 1959 with routes to Denver, Salt Lake City, and Billings using Douglas DC-3s, and later the Convair 340 and 580.The new terminal, designed by Gensler,[9] still blends with the unique surroundings of the national park with exposed wood, fireplaces, and nature photography throughout.Due to a short runway at high altitude, the largest aircraft seen regularly at the Jackson Hole Airport is the Boeing 757-200 operated by Delta Air Lines on flights to Atlanta.Due to these conditions, Jackson Hole Airport does not typically see stretched versions of aircraft such as the Airbus A321 or Boeing 737-900, as they become weight restricted when taking off.In the year ending December 31, 2019 the airport had 27,325 aircraft operations, average 75 per day: 37% general aviation, 29% air taxi, 33% airline and 1% military.
