For those of you who are going to Yellowstone National Park through Idaho, the Idaho Falls Regional Airport (IDA) in Bonneville County seems like the best solution. Only one airport in the state has more annual boarding passengers than the IDA.
But, unlike the busiest airport in Idaho, this one is pretty close to Yellowstone. In fact, the distance between the airport and the nearest park entrance is about 70 miles. If you want to enter Yellowstone through its West Entrance, you will have to cover a distance of a little bit over 100 miles.
There are three airlines that serve this airport. Allegiant Air offers direct flights to Las Vegas and Phoenix throughout the year, while Oakland and Los Angeles are the destinations that are available only at certain times of the year. Delta Connection is an airline that connects the airport to Salt Lake City, as well as Minneapolis/St Paul, although the flights to Minnesota are available only seasonally. United Express offers only seasonal flights from Idaho Falls Regional Airport to Denver International.
