O'Hare International Airport

Located at 10000 W O’Hare Ave, Chicago O’Hare International Airport (ORD) is more than just a place to catch a flight—it is the heartbeat of the Windy City’s connection to the world. Whether you’re a local taking the Blue Line in from Logan Square or a traveler passing through for the first time, you’ll quickly notice that O’Hare feels like a city within a city. It’s famous for its massive scale, but it’s the small, "Chicago-style" touches that make it stand out from other mega-airports.

One of the best parts about flying through O'Hare is the food. You don't have to settle for basic terminal snacks when you can grab a legendary bag of Garrett Popcorn or a world-class torta from Rick Bayless’s Tortas Frontera. If you have a long layover, the airport actually offers plenty of ways to kill time that don’t involve staring at a gate screen. You can find a quiet moment in the Yoga Room in Terminal 3, check out the colorful "The Sky’s the Limit" neon light tunnel between Concourses B and C, or even see a vertical aeroponic garden in Terminal 3 that grows fresh herbs for the airport restaurants.

Navigating such a big space is surprisingly easy thanks to the Airport Transit System (ATS), the automated "people mover" that zips you between all four terminals and the Multi-Modal Facility (where the rental cars and Metra trains are) in just a few minutes. For those looking for a bit of luxury or a place to work, the airport is packed with lounges and high-speed Wi-Fi. Plus, with the ongoing ORDNext upgrades, you’ll notice brand-new gates and modernized concourses that make the whole experience feel much more "2026" and a lot less like the crowded terminals of the past.

The airport is a 24-hour operation, though specific airline check-in desks and security checkpoints have their own schedules. Generally, Terminal 5 (International) keeps security open 24/7, while domestic checkpoints typically open around 3:30 AM or 4:00 AM and close after the last scheduled departures. Most shops and restaurants open early for the breakfast rush (around 5:00 AM or 6:00 AM) and wind down by 9:00 PM or 10:00 PM, though you can always find a few 24-hour grab-and-go spots in the main terminals.
