ORD Airport Car Rental — Chicago O Hare Airport

Chicago O'Hare International Airport (ORD) is one of the world's busiest airports and offers as many as 16 car rental companies, making it the largest car rental selection in all of Illinois. The airport is located 27 km northwest of Chicago's downtown via I-90/94. From O'Hare it takes 25–40 minutes to drive into Chicago Loop depending on traffic, and the Rosemont Entertainment District with Allstate Arena is reached in 5 minutes east.

Libertyville and Six Flags Great America to the north are reached in 35 and 45 minutes respectively. Rental cars at O'Hare are picked up at the dedicated Rental Car Center, accessed via the free ATS train from the terminals – plan for 15–20 minutes from gate to car. Book in advance during peak season and business travel days (Monday–Friday) when all 16 companies may have limited availability.

Choose I-294 south instead of I-90 if you're heading to southern Chicago to avoid the city's rush hour traffic. How do I find the rental cars at O'Hare? Take the free automated ATS train from Terminal 1, 2, or 3 to Rental Car Center.

From International Terminal 5, take a bus to the ATS station. How long does it take to drive from O'Hare to Chicago's downtown? Via I-90/94 it takes 25–40 minutes without traffic, but during rush hour the trip can take 60–90 minutes.

Can I return the rental car at Midway and pick it up at O'Hare? Yes, one-way rentals are possible with most of the 16 companies, but a one-way fee applies. Compare prices when booking.
