Idaho Falls Regional Airport — Idaho Falls, United States

IDA serves Idaho Falls Regional Airport, a mid-sized facility supporting eastern Idaho, including access to Yellowstone National Park and the Teton mountain range. The airport provides scheduled flights to major connecting hubs, making it a practical entry point for tourists heading to nearby national parks as well as business travelers tied to the region's agriculture and nuclear research sectors — the Idaho National Laboratory is located close by. IDA also supports general aviation and occasional charter operations. Its runway infrastructure accommodates regional jets comfortably, and the airport has expanded terminal capacity over the years to keep pace with growing tourism-driven demand in the Yellowstone gateway corridor.
