The passenger experience at O’Hare is shaped by its scale and constant activity. With four terminals—1, 2, 3, and 5—the airport serves as a primary hub for United Airlines and a key base for American Airlines, handling flights to over 249 destinations worldwide. Travellers find clear signage and a range of amenities, though the sheer size can feel daunting. Terminal 1, designed by Helmut Jahn, features a striking neon-lit tunnel connecting Concourses B and C, adding a touch of flair to the journey. Terminals 1, 2, and 3 are linked by pedestrian walkways, making movement straightforward for domestic travellers, while Terminal 5, the international hub, requires a ride on the free Airport Transit System (ATS), a light rail operating 24/7 every few minutes.
Accessing O’Hare from central Chicago is convenient, with the CTA Blue Line providing a reliable 24/7 connection to the Loop in about 50 minutes for just £3.80.
Taxis, rideshares, and regional buses are also available, with the Multi-Modal Facility (MMF) serving as the hub for car rentals, accessible via the ATS. For drivers, the airport connects directly to Interstate 190, with clear signage guiding to terminals and parking options, including the main garage, economy lots, and a free Cell Phone Lot for pick-ups.
The airport’s layout, spanning 7,627 acres, includes two sets of parallel runways and a complex of terminals. Terminals 1, 2, and 3 form a connected core for domestic flights, while Terminal 5 stands apart, handling most international arrivals and departures. The ATS and shuttle buses bridge the gap, though transferring to Terminal 5 can take extra time due to security rescreening for international passengers. The ongoing O’Hare 21 expansion, set to replace Terminal 2 with a modern global terminal by 2028, promises to streamline connections further.
Delays can occur, often due to the airport’s intersecting runway configuration, which reduces capacity in bad weather. Tarmac waits of 30 to 90 minutes are not uncommon when gates are scarce, and last-minute gate changes can catch travellers off guard. Checking airline apps and terminal screens is advisable. Baggage handling, particularly for international flights, can also slow things down, with occasional reports of lost or delayed luggage.
Dining at O’Hare offers a taste of Chicago, with options like Tortas Frontera in Terminal 3 serving fresh Mexican sandwiches and Publican Tavern in Terminal 3 offering local craft beers and hearty dishes. Terminal 5’s expanded food court includes Dunkin’ and Chick-fil-A, though many eateries close by 10 pm.
, limiting late-night choices. Retail spans duty-free shops in all terminals, fashion boutiques, and Chicago-themed souvenir stores like the Chicago Historical Society Gift Shop. An aeroponic garden between Terminals 2 and 3 supplies fresh produce to some restaurants, adding a unique touch.
Facilities cater to diverse needs, with free Wi-Fi, power stations, and a multifaith chapel in Terminal 2. The Hilton Chicago O’Hare, the only on-site hotel, connects to terminals via underground walkways, offering soundproofed rooms and day-use options. Nursing rooms, pet relief areas, and an urgent care clinic in Terminal 2 enhance comfort, while accessibility features like the Aira app for visually impaired passengers and ADA-compliant transport ensure inclusivity.
On-time performance varies, with O’Hare’s high traffic volume making it prone to delays, especially during peak periods or inclement weather. The airport’s modernisation efforts, including new runways and taxiways, aim to improve efficiency, but travellers should plan for extra time. Connections between Terminals 1, 2, and 3 are smooth thanks to airside walkways, though Terminal 5 transfers require additional planning due to customs and security processes.
O’Hare’s blend of functionality, local flavour, and ongoing improvements makes it a dynamic hub. With a bit of preparation, travellers can navigate its complexities and enjoy a seamless journey through one of America’s key airports.
