IDA Airport rental counters experience predictable busy periods:
Highest Volume: Afternoon (2-5pm) when flights from Denver and Salt Lake City arrive
Expected Wait Times: 0-15 minutes, plus brief waits possible during peak flight arrivals
Busiest Days: Friday afternoons, Sunday evenings and holiday periods
Seasonal Impact: Summer (June-August) sees significantly higher demand due to national park visitation
Time-Saving Tips:
The terminal doors at Idaho Falls Airport lock about 1 hour after the last flight and reopen at 5:00 AM, which affects after-hours returns:
Normal Hours: Rental counters generally operate from early morning until after the last scheduled arrival
Late Returns: After-hours drop boxes are available at the rental car return area
Important Note: If the terminal is closed (usually late night to early morning), you cannot return a car during this period
Early Morning Flights: If departing on a very early flight, return your car the evening before or be prepared to wait until 5am when the terminal reopens

Check multiple brands in one search and play with pickup/return times. A 10 AM pickup instead of 2 PM can dodge the afternoon rush and sometimes shows cheaper daily rates in our comparison tool.
Peak summer = higher prices. If you're hitting Yellowstone between June and August, reserve early for choice and price. For shoulder or winter months, last-minute deals often pop up, so keep an eye on rates and re-book if you see a drop.
Keep the rental clock under 24 hr blocks. Got a 6 AM departure? Return the car the night before, or shift pickup to later on day one, so you don't pay for an extra day you barely use.
Pick the smallest car that fits your trip. Downtown Idaho Falls and park roads are cruiser-friendly; in summer you won't need AWD, so a compact can save $10-$30 per day and burn less gas.
Refuel 1–2 miles from IDA. Phillips 66 on W Broadway or Costco (if you're a member) have lower prices than the rental company's prepaid option or bring-it-back half-empty penalty.
Round-trip usually beats one-way. Planning to finish in Jackson or West Yellowstone? Price both options—sometimes adding a quick return drive to IDA is cheaper than the one-way fee.
Book a car rental to drive to:

Mesa Falls Scenic Byway – 60 miles (97 km), 1 hour
What is the best time to arrive at IDA for a rental car pickup?
You'll usually find shorter waits if you arrive in the morning. People arriving in the afternoon (especially from Denver and Salt Lake City) might see short lines at the rental counters.
Can I return my rental car after hours if my flight departs early?
Yes, all rental companies have after-hours drop boxes. Just know that they lock the terminal building about an hour after the last flight leaves and reopen it at 5:00 AM. So, for very early flights, you may need to drop off your car the evening before.
Is there a gas station at the airport?
No, the airport does not have a gas station on its property. The closest one is a Phillips 66, about 1.5 miles (2 km) from the terminal on West Broadway.
How early should I arrive to return my rental car before a flight?
For flights within the US, you should plan to arrive 1.5 to 2 hours before your plane leaves. Returning the car usually takes 10–15 minutes and getting through security at the small IDA airport is often quick.
Can I pick up a rental car in Idaho Falls and drop it off at another location?
Yes, you can rent a car one-way, but the rental company will usually charge an extra fee. In the summer, many people use this option to drop cars off in Jackson Hole or West Yellowstone.
Do I need a 4WD vehicle to visit Yellowstone and Grand Teton?
In the summer (May–October), a standard car is fine for all the park roads. If you travel in the winter or during the spring and fall, you should get a vehicle with AWD or 4WD. This is very important if you plan to drive to Jackson Hole over Teton Pass.
Are there any road restrictions I should be aware of when renting from IDA?
Most rental companies let you drive on all paved roads and well-kept gravel roads. They generally do not allow you to drive off-road. Some gravel Forest Service roads might not be covered by your rental insurance. You should check your specific rental agreement to see what it says.
