Global Terminal


New O'Hare Global Te​rminal 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 Chicago 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. 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 Global Terminal will integrate domestic and international terminal operations and enhance passenger and baggage connectivity through:
    • Additional gates
    • Co-location of domestic and international arrival 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​
