ORD Concourse B Guide (Terminal 1): Gates, Food & Tips

Terminal Overview

Concourse B is part of Terminal 1 at Chicago O’Hare (ORD) and is primarily focused on United Airlines operations. You’ll mostly see domestic departures and arrivals here, with some passengers connecting onward to United’s international flights elsewhere in Terminal 1 (and to other terminals). Because Terminal 1 is United’s hub at ORD, Concourse B is built for high-frequency departures and quick connections rather than a quiet, boutique feel.

As a traveler, the experience is efficient and familiar: lots of gate seating, busy peak-time corridors, and reliable wayfinding with clear gate numbering from B1 through B24. The upside is convenience—many flights, frequent rebooking options if weather hits Chicago, and straightforward access to the rest of the airport via post-security tunnels and the landside Airport Transit System (ATS).

Airlines & Destinations

  • Primary airline: United Airlines (hub operations in Terminal 1; Concourse B gates B1–B24).
  • Other Terminal 1 airlines (not always on Concourse B specifically): Lufthansa and All Nippon Airways also operate from Terminal 1.
  • Alliance: United is part of Star Alliance, so many Star Alliance connections route through Terminal 1 even if the exact gate is in Concourse B or C.
  • Typical destinations: You’ll commonly find United flights to major hubs and business routes (for example, New York-area, Washington, Denver, Houston, San Francisco/Los Angeles) plus extensive Midwest and national domestic service.
  • Connections: If you’re connecting to a United or Star Alliance international flight, you may still stay within Terminal 1 but switch between Concourse B and Concourse C.

Layout & Navigation

Concourse B is a single linear concourse within Terminal 1, with gates numbered B1–B24. The concourse connects into Terminal 1’s central areas where you’ll find major services and access points to other concourses and terminals. If you’re meeting friends or splitting up for food, use your gate number (for example, “near B11”) as the simplest landmark—everything is organized around the gate sequence.

  • Security: Terminal 1 security checkpoints feed passengers into the concourses; once you’re airside you can follow signs to B gates. (Checkpoint locations can vary by time of day, but signage is strong.)
  • Walking times: Within Concourse B, walks are usually manageable; most end-to-end walks feel like 5–10 minutes depending on crowds and how far apart your gates are.
  • Connecting to other terminals (post-security): You can walk through underground pedestrian tunnels between terminals: Terminal 1 ↔ Terminal 2 in about 10–12 minutes, and Terminal 1 ↔ Terminal 3 in about 15–20 minutes. This is helpful if you’re connecting without wanting to exit and re-clear security.
  • Connecting landside: The free Airport Transit System (ATS) runs 24/7 from the lower level, arriving every 3–5 minutes; travel between terminals is typically 5–10 minutes.
  • Terminal Transfer Bus (TTB): During daytime hours, a transfer bus can help you switch terminals without re-screening; at night, you may need to exit and use ATS, then re-clear security.

Amenities & Services

  • Food highlights (Terminal 1): Expect lots of quick options. Common favorites include Tortas Frontera (Mexican), plus familiar fast-food stops like McDonald’s, Dunkin’, and Auntie Anne’s.
  • Charging / power: If you need guaranteed charging near Concourse B, head toward the documented charging station areas at B5, B11, B12, B14, and B19.
  • Lounges: Terminal 1 is United’s home base at ORD, so lounge options are typically oriented around United customers (availability and access rules vary by ticket and status). Follow lounge signage once you’re airside.
  • Shopping: You’ll find typical airport convenience retail—snacks, travel essentials, and reading material—clustered in the main passenger corridors.
  • Accessibility: ORD is set up for step-free travel with elevators, escalators, and accessible routes between levels; ATS is also accessible. If you need assistance, request wheelchair help through your airline in advance.
  • Family needs: You’ll generally find restrooms and baby-changing options throughout Terminal 1; if you need a quieter reset, aim for less-crowded gate ends rather than the busiest central corridors.

Practical Tips

  • Best spots for long layovers: Pick a base near gates with known charging—B11–B14 is a solid target—so you can work without hunting for outlets.
  • Quietest places to rest: Concourse B gets loud at peak waves. For a calmer break, walk a few gates away from the busiest restaurants and aim for seating clusters closer to the far ends of the concourse (near the lowest or highest B gate numbers).
  • Power strategy: If your battery is low, go directly to B5, B11, B12, B14, or B19 rather than circling. Those are the most reliable “known” charging areas in Concourse B.
  • Wi‑Fi: O’Hare offers airport Wi‑Fi; connect to the official network shown on signage and allow a couple minutes for the captive portal to load, especially during delays or weather events.
  • Connection planning: If you’re connecting to Terminals 2 or 3, use the post-security tunnels when you can (no re-screening). If you must switch to Terminal 5, plan extra time and consider ATS or the transfer bus depending on the hour.
