The 4 best lounges at Denver International in 2026

How Denver's concourses shape the choice

Denver has three parallel concourses, A, B and C, joined to the main terminal by an underground train. Concourse A also has a pedestrian bridge from the terminal. All three are airside and connected, so you can ride to any lounge on this list after one security check. That is useful, because the airport has far fewer lounges than its traffic suggests. We looked at why in our story on the Denver lounge problem.

The current map is simple. United's clubs are on A and B, Delta's club is on A, and American Express and American Airlines sit on C. Only four lounges have photos on file, which is why this year's list stops at four. The Capital One Lounge on Concourse A rates 4.7 and would sit second, and the east United Club on B rates 4.5, but neither has a photo yet. For the airline networks, see our rankings of every Centurion Lounge and every United Club.

1. The Centurion Lounge

The Centurion Lounge leads Denver at 4.8. It opened in 2021 on the Concourse C mezzanine near gate C46, up the escalator from the concourse level. It holds about 240, pours craft cocktails and has two showers. Hours are 05:00 to 22:00. Coffee, crowding, drinks, power, quiet, restrooms, service, showers, views, Wi-Fi and workspace all scored five. Platinum and Business Platinum cardholders pay 50 dollars per guest, or bring guests free after 75,000 dollars of annual spend, and Centurion members bring two guests free. Since July 8, 2026, guests must be on the same flight as the cardmember, and layover entry opens five hours before the connecting departure. The train ride from A or B is short, and this is the one lounge in Denver worth it.

2. Delta Sky Club

The Delta Sky Club rates 4.5 after a 2026 expansion. It is on level 4 on the north side of the Concourse A center core, with the entrance just past the pedestrian bridge from the terminal. It holds 230 with a full bar and no showers. Hours run 04:30 to 00:15, the longest of any lounge here, which makes it the safe choice for the first and last banks of flights. Crowding, drinks, food, quiet, restrooms, service and workspace scored five. Members and eligible cardholders bring up to two guests at 50 dollars each, entry opens three hours before a same-day Delta or partner departure, Basic fares are excluded, and US Amex Platinum holders get ten visits a year while Delta Reserve holders get fifteen.

3. United Club (B West)

The United Club (B West) is United's Denver flagship, rated 4.5. It reopened in 2025 as a two-level club near gate B32 with seating for 600, the largest room at the airport. Hours are 05:00 to 21:00. There is a full bar but no showers. Coffee, food, power, service, views and workspace scored five. Individual members enter alone and pay 59 dollars per guest, All Access members bring two adults or one adult plus children, United Club cardmembers bring one guest plus children, and Star Alliance Gold members bring one guest on the same flight. One-time passes cost 59 dollars within three hours of departure.

4. United Club (A)

The United Club (A) rates 3.6 and opened in 2023 near gate A25 on the west side of Concourse A. It spans two levels with a lodge feel and a fireplace, holds 400 and runs 05:00 to 20:30. Cleanliness, quiet and seating scored five, but coffee, drinks, food, restrooms, service, Wi-Fi and workspace all came in at three. Guest rules match B West. It is a good place to sit quietly before an A gate flight, but if you have an hour to spare, B West has better food and the train is quick.

What did not make the list

Three Denver lounges were left out for lack of a photo: the Capital One Lounge on Concourse A, the east United Club on Concourse B, and the American Airlines Admirals Club on Concourse C, which rates 3.9. United Club Fly on Concourse B rates 1.4 and was never a contender. As the photo gaps close, the Capital One Lounge in particular should move this ranking around.

Where to look next

Our rankings use ratings across fourteen metrics, explained on the methodology page. The generated page at the DEN top five updates as reviews arrive, and the airport page lists all eight lounges across the three concourses.
