We also submitted for Bowman to Kintla early August, as well as a Loop around fifty, and another around Rising Wolf mountain with some add-ons.
Fwiw, we fly with Southwest so you can cancel or reschedule as needed, which allows you to buy when they're cheap. Planning to fly to Spokane and rent a car if it works out. Car rentals are half the price of Missoula/Kalispell/etc too. Obviously a lot of travel though. Best option we found for our needs/resources.
