Background

United Airlines primarily operates out of Terminal 1 at O'Hare International Airport (ORD) in Chicago. This terminal serves as a hub for United's domestic flights and includes two main concourses, B and C. Concourse B is located within the main terminal building, while Concourse C is accessible via an underground walkway. Both concourses are well-equipped with plenty of amenities, including shops, restaurants, and United Club lounges for passengers looking to relax before their flights. Terminal 1 is where most United passengers will check in and depart for their domestic flights, though it also handles a few international flights. However, for some international routes, especially those arriving into Chicago, United may utilize Terminal 5, which is the designated international terminal. Arrivals from overseas destinations are usually processed through Terminal 5, where customs and immigration services are located. It’s always important to double-check your flight information before traveling, as gate and terminal assignments can change, especially for international flights. United's Premier Access passengers can take advantage of faster check-ins and priority boarding at Terminal 1, enhancing their travel experience with streamlined services. Whether you're flying domestically or internationally, United's presence at O'Hare makes traveling through the airport relatively convenient and efficient.
