KJAC is the ICAO code for Jackson Hole Airport (IATA JAC), located in Jackson, WY.
Jackson Hole Airport (KJAC) is the only commercial airport in the United States located inside a national park — Grand Teton National Park — and sits at 6,451 feet elevation in the Snake River valley. It serves Jackson, Wyoming, and the year-round ski and outdoor circuit that makes Jackson Hole one of the highest-density UHNW private-aviation destinations in the Mountain West. Commercial service is significant (American, Delta, United, JetBlue, Alaska, Frontier seasonal), and private aviation runs roughly parallel — Signature and Jackson Hole Aviation are the two FBOs, both with substantial winter capacity demands.
Runway 1/19 is 6,300 feet, which is workable for heavy and ultra-long-range jets at typical loads but is genuinely tight on hot summer afternoons with heavy payloads — operators routinely run runway analysis and tanker accordingly. Mountain weather is the dominant operational factor: orographic turbulence, sudden ceiling drops in winter, density altitude effects in summer that can push effective takeoff altitudes north of 9,000 feet, and the national-park noise overlay that constrains certain departure profiles. The Hill Climb, the Old West Days, the Jackson Hole Film Festival, and the structural peak around Christmas-New Year and President's Day weekend all drive ramp pressure that brokers should plan for at least two months out. The town of Jackson is 10 minutes away by car; Teton Village (the ski mountain) is 25 minutes.
Jackson Hole Airport is a public airport located seven miles (11 km) north of Jackson in Teton County, Wyoming, U.S. In 2019, it was the busiest airport in Wyoming by passenger traffic with 455,000 passengers. During peak summer and winter seasons, Jackson Hole offers nonstop airline service from up to 15 destinations across the United States. The airport is served year-round by Alaska Airlines, American Airlines, Delta Air Lines, and United Airlines and seasonally by Sun Country Airlines.
