Idaho Falls, which is in the line of totality, is served by Idaho Falls Regional Airport. Boise, which will see a partial eclipse, is served by Boise Airport. From Boise, however, you can drive into the line of totality.
As in Wyoming, international travellers will have to pick up a connecting flight from one of the major entry points in the US.
The NASA Google map of the eclipse path also shows roads which you can use to decide on the best route to your viewing place in Idaho.
