All trips have a starting point. Ours was Great Falls International Airport. I love that it's small. We got through security fairly quick and had some time to chill before our flight. The lady at the gift shop/food area was very pleasant to talk to. The airport is neat and tidy and decorated nicely. Brayden loves looking at their Model Airplane Collection. They have the largest model airplane collection in the world according to Roadside America. edit.
