Global Terminal

The City has awarded a lead architect contract to Studio ORD to design the new O'hare Global Terminal and Global Concourse. Led by Jeanne Gang, this team will shape the vision for the largest expansion in O'Hare's history!

The centerpiece of ORD21 will be the new O’Hare Global Terminal, a reflection of Chicago-O’Hare’s current position as the best-connected hub in the United States, and a leading global gateway.

For the first time at O’Hare, this new terminal will connect domestic flights non-stop to destinations around the world from under one roof. It will also provide opportunities for United, American and their alliance partners to continue steady growth at O’Hare—which will result in greater connectivity options and competitive pricing for our travelers.

During a rigorous and historic competition, five of the best architecture firms from around the world submitted their visions for what will be one of the most important construction projects in modern history.

New O’Hare Global Terminal Fast Facts:

  • At 2.2 million square feet, the new O’Hare Global Terminal will be one of the largest and most cutting edge terminals in the nation, dramatically improving the first impressions of tens of millions have when visiting our city every year.
  • It will more than double the space of today’s Terminal 2, replacing it with an expanded, light-filled arrivals hall.
  • The O’Hare Global Terminal is valued at $2.2 billion and is slated to break ground in 2023. The City will work with its airline partners to ensure a timely, cost-efficient delivery of the new O’Hare Global Terminal and throughout the entire $8.5 billion terminal capital program.
  • While building the Global Terminal is a significant undertaking, at no time during this process will gate capacity be reduced. The new satellite concourses will provide enough gate capacity to shift activity from the existing Terminal 2 to the satellites, enabling the O’Hare Global Terminal to be constructed.
  • The O’Hare Global Terminal is currently scheduled to open in December 2028.
  • The Global Terminal will integrate domestic and international terminal operations and enhance passenger and baggage connectivity through:
    • Additional gates

    • More space for concessions, lounges, and public amenities
    • State-of-the-art baggage systems
    • Expanded immigration and customs facilities
    • Ability for airlines in alliances to consolidate operations within a single terminal facility, positioning O’Hare to be a global alliance hub for all three major airline alliances:
      • Star Alliance, of which United Airlines is a member in the O'Hare Global Terminal
      • Oneworld, of which American Airlines is a member in the O'Hare Global Terminal
      • Skyteam, of which Delta Air Lines is a member in Terminal 5
