There are relatively frequent flights and multiple options for the JS. Anywhere else and you’ll be at the mercy of smaller, generally full aircraft with senior (and typically on-line) commuters with JS priority.
It’s doable, but anything more than one-leg from Montana can be challenging. Feel free to PM for any specific questions, and best of luck.
