Located about 17 miles northwest of the Chicago Loop, it features four active terminals and a wide range of amenities, including high-end dining, local Chicago favorites, and several luxury lounges. Navigating this massive facility is simplified by the ATS (Airport Transit System) people mover, which connects all terminals and the multi-modal transport facility.

Known for having one of the most scenic approaches in the country, passengers often get a bird's-eye view of downtown skyscrapers before touchdown. The airport consists of two main terminals, with Terminal 2 offering modern upgrades and a diverse selection of local eateries that reflect the city's coastal culinary culture.
