United & American Pressure Pushes O’Hare To Fast-Track 24-Gate Concourse E

Facing tight gate capacity and surging flight schedules, Chicago Department of Aviation (CDA), United Airlines, and American Airlines have agreed to restructure the multibillion-dollar ORDNext expansion project. Under the new agreement, Chicago will break ground later this year on the first phase of the brand-new, 24-gate Concourse E.

The strategic shift accelerates a concourse that was previously delayed due to budget negotiations. By delivering satellite gates earlier, O'Hare ensures hub carriers can maintain operations without severe capacity constraints when the demolition of Terminal 2 begins to make way for the future O'Hare Global Terminal.

Why the Construction Sequence Changed

• Intense Hub Competition: Aggressive expansion and tight gate reallocations between United and American pushed terminal capacity to the brink, prompting FAA flight limits at O'Hare through fall 2027.
• Preventing Gate Shortages: Demolishing Terminal 2 without replacement capacity would have stripped dozens of active gates offline. Fast-tracking Concourse E creates a vital buffer.
• Cost & Budget Alignment: Phasing Concourse E into two stages preserves the approved modernization budget while accelerating the construction timeline of the Global Terminal.

ORDNext Revised Construction Timeline

Project Phase	Target Completion	Scope & Gate Impact
New Concourse D	Late 2028	19 new gates (already under construction since 2025)
New Concourse E (Phase 1)	2030	14 new gates; breaks ground late 2026
O'Hare Global Terminal	2033	Replaces Terminal 2; construction runs 2029–2033
New Concourse E (Phase 2)	2034	Adds final 10 gates, bringing Concourse E to 24 total gates

What to Expect from the New Concourse E

• Size & Location: A multilevel, 460,000-square-foot satellite concourse situated directly west of Concourse D.
• Aircraft Flexibility: Designed to accommodate regional and narrow-body aircraft for domestic and pre-cleared international arrivals.
• Tunnel Connections: Seamless passenger transit via an underground pedestrian tunnel linking Concourse E, Concourse D, and the O'Hare Global Terminal.
• Passenger Amenities: Modernized airline club lounges, expanded retail, and elevated dining concessions.

When ORDNext is fully completed, the addition of the new concourses and Global Terminal will expand O'Hare's total gate capacity by 14 percent, giving Chicago one of the world's most modern international aviation hubs.
