@flightfriend: Terminal 1 at Chicago O’Hare (ORD) is home to United Airlines. Terminal 1 has two concourses: Concourse B (B gates) and Concourse C (C gates). *A concourse is a long wing/section of a terminal. You may need to move between concourses to reach your gate, sometimes by walking, taking a train, or using a shuttle.* At Terminal 1, security is connected to Concourse B. Passengers who are departing from a C gate will need to take the underground walkway to Concourse C, which connects B and C. Stay tuned for tomorrow’s post which breaks down changing terminals at Chicago O’Hare! 🛫 #ohare #chicagotiktok #ord #ohareairport #creatorsearchinsights
