What airlines use terminal 3 at ORD?

Terminal 3 at Chicago OHare International Airport (ORD) primarily serves as the major domestic and select international hub for American Airlines alongside several partner carriers and independent airlines. Navigating the correct terminal can sometimes feel confusing, especially with code-share flights and various alliance connections.

Primary Carriers Operating Out of Terminal 3

American Airlines handles the vast majority of traffic in Terminal 3 across its mainline operations spanning concourses G, H, K, and L. In addition to American Airlines, several key domestic and international partner airlines operate flights from this terminal. American Airlines (Mainline): The anchor tenant occupying the majority of gates across concourses G, H, K, and L. Aer Lingus: Operates select transatlantic flights. Alaska Airlines: Operates out of Concourse L. British Airways: Manages specific international departures from Terminal 3. Contour Airlines: Serves regional destinations. Iberia: Operates select partner flights within the alliance network. Japan Airlines (JAL): Operates key transpacific routes.

Understanding Gate Layouts and Code-Shares

Terminal 3 features four distinct concourses (G, H, K, and L) that are fully connected post-security, allowing seamless transfers if you are flying on partner airlines.

Lets be honest - changing gates across these sprawling concourses can easily add 15 to 20 minutes to your walk time, so checking your boarding pass monitor as soon as you clear security is always a smart move. Many travelers get confused by code-share agreements where a ticket is booked through American Airlines, but the actual physical flight is operated by an alliance partner. Always verify whether your flight departs from Terminal 3 or requires a transfer to Terminal 5 for international departures.

Navigating Connections Between Terminal 3 and Other Terminals

Moving between OHare terminals is straightforward once you know the layout. Terminals 1, 2, and 3 are physically connected post-security and via an underground pedestrian walkway pre-security, making it entirely possible to walk between them without exiting to the street.

However, if you need to reach Terminal 5 for international arrivals or non-alliance carriers, you must use the Airport Transit System (ATS), a 24-hour automated people mover system. Give yourself extra time if you are transferring between Terminal 3 and Terminal 5, as you will need to clear security screening again upon entering Terminal 5.

Navigating Terminal 3 Transfer Mishaps

Minh, a frequent traveler flying from Des Moines to Tokyo via Chicago O'Hare, booked his ticket through American Airlines with a connecting leg operated by Japan Airlines.

He initially assumed all international flights left from Terminal 5 and almost took the ATS train right after landing, which would have wasted precious time.

Fortunately, after checking his boarding pass closely at the gate monitor, he realized his Japan Airlines flight actually departed directly out of Terminal 3.

He avoided a needless trip across the airport, utilized the post-security walkways to reach Concourse K smoothly, and boarded his flight with time to spare.
