The town of Jackson has an airport (Jackson Hole Airport - JAC) with many direct connections to major US cities. Alaska, American, Delta, and United Airlines all offer year-round flights to and from Jackson Hole. It is located around 10 miles away from the workshop hotel. Either a taxi or shuttle can be used to reach the hotel, and Uber/Lyft are also available for transportation.
Landing or taking off from the airport offers some spectacular views of the Grand Tetons!
