First and foremost, book in advance. Car rentals at Bozeman Airport can be extremely expensive during peak times. The above search is for a Premium SUV December 22 – January 3, 2012. As you can see, SUV rentals command an extremely high price in Bozeman. At this time, economy car rentals were $100/ day as well. The moral of the story- book in advance. Options 2; think outside of the Big Box. We checked with the off-airport rental car companies, and although they were almost completely booked out, Toyota Rent-A-Car had a 2012 Sequoia for $120/ day and Phasmid Rentals had a 2012 Chevrolet Suburban z71 for $150/ day. Nobody likes wasting money on a rental car, so think in advance and if you forget to do that- think outside of the Big Box.
