Which Terminal Does United Use at O’Hare?

When flying with United Airlines from Chicago O'Hare International Airport (ORD), knowing the correct terminal is crucial for a smooth travel experience. O’Hare, one of the busiest airports in the world, serves as a major hub for United Airlines, and the airline operates primarily out of Terminal 1, with some services also extending to Terminal 2 and the Terminal 5 international facility. This guide provides a comprehensive overview of the United Airlines Chicago O'Hare Airport Terminal, including gate locations, lounges, transportation tips, and other essential services.

United Airlines: A Major Presence at Chicago O'Hare

United Airlines maintains a significant operational presence at O'Hare International Airport, with the airport serving as one of its primary domestic and international hubs. From ORD, United offers hundreds of daily flights to cities around the world. Because of this extensive network, understanding the layout and functions of the United Airlines Chicago Ohare Airport Terminal is essential for every traveler.

Terminal 1: United Airlines' Main Hub

Terminal 1 is the main terminal for United Airlines at O'Hare. Designed by Helmut Jahn and known for its distinctive architectural style, Terminal 1 is divided into Concourse B and Concourse C:

• Concourse B: This concourse is located in the main terminal building and is where most United domestic flights depart and arrive.

• Concourse C: Accessible via an underground pedestrian tunnel from Concourse B, this satellite concourse also hosts numerous United Airlines gates, primarily for domestic and some international departures.

Terminal 1 is known for its efficiency and wide range of amenities, catering almost exclusively to United Airlines and its regional partner, United Express.

Gates in Terminal 1

• Concourse B: Gates B1-B22

• Concourse C: Gates C1-C32

These gates accommodate a high volume of daily United flights, including connections to major cities and United hubs across the country.

Terminal 2: Additional United Express Operations

Although Terminal 1 handles the majority of United flights, Terminal 2 is occasionally used for select United Express regional flights. Gates E and F in Terminal 2 may host flights operated under the United Express brand. However, most travelers flying with United will still check in and process their security screening through Terminal 1.

It is essential to double-check your flight details when booking or checking in, as last-minute gate changes can redirect certain regional flights to Terminal 2.

Terminal 5: United's International Arrivals Terminal

For international arrivals into the U.S., United Airlines utilizes Terminal 5, which is O’Hare's designated international terminal. All passengers arriving on international flights with United Airlines (excluding those from airports with U.S. Customs pre-clearance) will be processed through Terminal 5 for customs and immigration.

After clearing customs, travelers connecting to a domestic United flight will need to transfer from Terminal 5 to Terminal 1.
