Denver International Airport offers multiple rental car companies inside its complex. Passengers who are willing to roam around the city without relying on public transport must choose the right rental company at DEN. The counter queues at the centralised Rental Car Center can take more than an hour during peak arrivals without a reservation. Hence, renters must always book their suitable cars in advance from the available ones. While the best car rental Denver Airport provides guaranteed vehicles, some may only offer similar models in the same category, including economy, compact, SUVs, pickup trucks, and more.
How Car Rental Works at Denver Airport
All the major car rentals at Denver Airport operate from the Rental Car Center (RCC), a consolidated facility located south of the Jeppesen Terminal along Pena Boulevard. A complimentary shuttle bus connects the terminal to the RCC, running continuously from Island 4 on Level 5 of the arrivals level. The shuttle ride takes approximately five to ten minutes, after which renters either proceed to the counter or, if enrolled in a loyalty programme, skip directly to the vehicle garage.
At DEN, join the free loyalty programme of the chosen company and add the renter’s member number to the reservation before arrival. This is the only reliable way to bypass the counter queue and go straight to the car. At DEN’s busiest arrival times, Friday evenings, Sunday afternoons, and long weekends, the difference between a five-minute pickup and a 60-minute wait.
