Satellite Concourse 1 "began vertical construction in April 2026 with a targeted completion date of late 2028" - a season rather than a day, and one that has already moved.^[1]

First promised for 01/01/2026; now 3 years later. Stated: the 2018 programme approval had the whole $8.5 billion O'Hare 21 rebuild, satellite concourses included, "supposed to be finished by 2026"; the concourse's completion is now targeted for late 2028, with the Global Terminal pushed to 2032 and the programme to 2034.

O'Hare's Satellite Concourse 1 Is Finished

The first of two satellite concourses west of O'Hare's terminal core, designed by Skidmore, Owings & Merrill with Norviska and designated Concourse D, is reached by an underground tunnel from the terminals. Vertical construction started in April 2026; the $1.45 billion concourse is the first piece of the O'Hare 21 rebuild to be delivered, a programme approved in 2018 at $8.5 billion and now put at roughly $12 billion in current dollars.

Satellite Concourse 1, designated Concourse D, has a budget of $1.45 billion; vertical construction began in April 2026 and completion is targeted for late 2028, the date this pin marks; its design was unveiled in November 2025^[1]
The concourse "was designed by Skidmore Owings and Merrill and Norviska"^[1]
It is the first of two satellite concourses totalling about 1.3 million sq ft, linked to the terminals by an underground tunnel; the second satellite has no firm start date^[1]
O'Hare 21 was approved in 2018 with an $8.5 billion budget, which the source says is "now approximately $12 billion in current dollars", with construction now extending to 2034 against an original 2026 target^[1]
The programme's other pieces: a new 2.2 million sq ft Global Terminal (Studio Gang within team Studio ORD, design-build by a joint venture led by Clark Construction and Clayco) at about $2.2 billion, currently targeted for 2032 and replacing Terminal 2; the Terminal 5 expansion ($1.2 billion, built March 2019 to 2023, ten new widebody gates); and the ElevateT3 renovation at about $300 million^[1]
A May 2024 agreement between Mayor Brandon Johnson and the airlines resequenced the work to Satellite 1, then the Global Terminal, then the second satellite, pushing completion from 2032 to 2034; an FAA environmental review had already taken four years, with approval in November 2022^[1]
The article gives no gate count for the concourse itself^[1]
