Just finalized our arrangements for Montana in September. I am happy to report that an airline ticket into Bozeman is half what it was last year
($322.00) which for two of us is like getting a free float trip and three nights lodging where we stay. This is also at least $150 less than any other time in the last four years. I suppose it depends on where you are traveling from but it sure seems that if it was too expensive before, it might not be so bad now.
Bozeman’s served by a number of airlines (so is Billings), which also helps keep prices a little lower than other cities. My in-laws live in Whitefish and we can’t get plane tickets for under $700, so we fly into Spokane and drive over. Car rentals in BZN also tend to be a little cheaper than other cities in MT and they give you unlimited mileage, unlike Missoula and Kalispell. Hope you catch a lot of fish.
If you’re going to fish in Yellowstone NP, please be aware that the road from Madison-Norris is going to be closed after Aug 17. That’s going to add a lot of travel time if you’re trying to get between West Yellowstone and the north side of the park (Gardiner, Cooke City, etc).
