Denver International has 6 tracked projects. See what is open, under construction, announced, or still only rumored — with a source beside every claim.
The former title-holder: United's largest club in the network at ~35,000 sq ft until Houston's 54,000 sq ft Terminal B North club opened on October 22, 2026 and took the crown. Still the benchmark for what United meant by a 'big' club.
United's fourth Denver lounge: 33,000 sq ft over two levels opposite gate B32, 600+ seats, two bars. Its opening pushed Denver to ~100,000 sq ft of United club space seating nearly 1,600 — the biggest club footprint at any hub.
The original grab-and-go experiment, between gates B61 and B63: about 1,500 sq ft, ~16 seats, coffee and cold food for connectors. The concept United later copied to Houston.
Announced in May 2023 as coming 'in a couple of years' — three years on, United has said only that design work has started. No construction, no size, no date. Denver would be the seventh and final domestic Polaris lounge, planned for the A-West mezzanine. The cleanest example on this page of announced-with-a-date-that-evaporated.
DEN's $700M, 11-gate westward extension of Concourse C under its Vision 100 plan. The airport says there's a 'waiting list' for the gates but hasn't said who gets them — United and Southwest are the presumed contenders. Airport project; United connection unconfirmed.
DEN's multi-year rebuild of the main terminal — the part every United flyer touches is security: the 17-lane East Checkpoint opened in August 2025 (early and under budget), an eight-lane North Checkpoint on Level 5 — mainly for connecting international passengers, open 12:30–8:15 p.m. — opened by late October 2026 (announced October 22) alongside a redesigned international arrivals area, and the whole program is substantially complete by end of 2027.
Great Hall terminal overhaul is the clearest headline at DEN: DEN's multi-year rebuild of the main terminal — the part every United flyer touches is security: the 17-lane East Checkpoint opened in August 2025 (early and under budget), an eight-lane North Checkpoint on Level 5 — mainly for connecting international passengers, open 12:30–8:15 p.m. — opened by late October 2026 (announced October 22) alongside a redesigned international arrivals area, and the whole program is substantially complete by end of 2027. Across the full list, 4 of 6 projects are led or jointly built by United; the rest belong to the airport authority and affect United's operation without being United capital projects.
The FAA tracker currently labels DEN live on electronic flight strips. The tower rollout is tracked separately from United's terminal and club construction.
6 projects are tracked at DEN: United Club B-East, United Club B-West, United Club Fly, B-East, Polaris Lounge Denver, Concourse C-West extension (11 gates), Great Hall terminal overhaul. Each item is labeled by current status and by whether United or the airport authority is doing the work.
3 projects are under construction or announced, 3 are already open, and the remaining items are explicitly labeled if they are only rumored.
Concourse C-West extension (11 gates) carries a published target of timing not finalized. It remains labeled announced until a source confirms that it opened.
