Deposits held on your card at Boise Airport range from $200 with Budget or Sixt to $299 with Avis, and none of the 6 companies accept a debit card. All 6 desks are strictly credit-card only for the deposit at pickup. You must bring a credit card in the lead driver's name, as you cannot filter for debit card acceptance on these rentals. Any additional counter extras are listed under each car with their prices.

If you bring your own child seat, check your airline's rules first: most carry one free, some charge.

All 6 desks at Boise Airport refuse debit cards entirely, so turning up without a credit card in the primary driver's name means leaving without a vehicle. Counter wait times can also test your patience after a flight, stretching to 33 minutes at Budget. With long highway drives common across the region, spending hours in an underpowered car makes that tiny daily saving feel like a very long sentence.

Only 50% of prices at Boise Airport are full tank out, full tank back, so read the fuel line under the car before you book.

For most trips, choose an Intermediate car like a Volkswagen Jetta at Boise Airport, which costs around $71 a day for October 2026. It seats 5 people but holds 3 bags, so larger groups will find luggage tight on long highway journeys. You can step down to a Compact Nissan Versa for $62 or step up to a Fullsize Chevrolet Malibu with 4 bags of space for $85. 100% of cars offered are automatic, and there are no electric or hybrid models in the fleet, so expect standard petrol power.
