Denver International was the first US airport to open a Capital One Lounge, and in March 2024 it added an Amex Centurion Lounge in Concourse C. That combination gives DEN one of the strongest credit-card lounge lineups outside the major coastal hubs. The lounges are split across three concourses, and the only way to move between them airside is the AGTS underground train.
The most useful thing to know about DEN lounges: the AGTS train runs every two minutes, takes about two minutes between concourses, and operates 24/7. A Capital One Lounge visit on a Concourse C departure is realistic if you arrive at the airport early, but you should not plan it on a tight connection.
Here is every lounge at DEN, organized by concourse, with the credit cards that get you in and what to expect.
DEN Terminal Layout
Denver International has one main terminal (the Jeppesen Terminal) and three concourses: A, B, and C. United operates one of its largest hubs out of Concourse B and has three United Clubs there. Frontier and most international carriers use Concourse A. Southwest dominates Concourse C, with United and Delta also serving select gates.
A pedestrian bridge connects the Jeppesen Terminal to Concourse A airside, so passengers departing from Concourse A can skip the train. Concourses B and C are only reachable via the AGTS underground train, which runs every two minutes from a station beneath the main terminal.
Capital One Lounge (Concourse A)
The Capital One Lounge at DEN was the first Capital One Lounge to open, launching in November 2021 near gate A38. After an expansion, the space now runs about 11,000 square feet on the upper level with a chef-curated menu, hot and cold food stations, a full bar with Colorado craft beer and regional wines, shower suites, a Peloton cycling room, nap pods, and a kid-friendly area.
Access requires a Capital One Venture X (unlimited free visits with two free guests), the Capital One Venture (two free visits per year, then $45 each), or the Capital One Spark Cash Plus. Other Capital One cardholders pay $45 per visit. Non-Capital One cardholders pay $65 walk-in.
The lounge enforces a 3-hour maximum stay tracked from check-in. Reservations through the Capital One mobile app are recommended on Friday afternoons and Sunday evenings when capacity fills. As of February 2026, authorized users no longer get automatic lounge access; primary cardholders can pay $125 to add unlimited access for up to 4 authorized users.
Centurion Lounge (Concourse C)
The Centurion Lounge at DEN opened in March 2024 and is one of the newer locations in the Centurion network. It sits on the upper level of Concourse C near gate C29 at approximately 14,650 square feet across two stories. The menu features Colorado regional cuisine, the cocktail program leans into Western whiskeys and high-altitude wines, and the outdoor terrace overlooks the Rockies on clear days.
Access requires an Amex Platinum, Business Platinum, or Centurion card with a same-day boarding pass. The Delta SkyMiles Reserve grants access when flying Delta. No Priority Pass entry.
Guests cost $50 per adult and $30 per child (ages 2 to 17). Free 2-guest access requires $75,000 in eligible Amex purchases in the current or prior calendar year. A 5-hour pre-departure time limit applies across the Centurion network as of 2026.
This is the only Centurion Lounge on Concourse C. If you are departing from Concourse A or B with an Amex Platinum, you will need to ride the train both ways.
Delta Sky Club (Concourse A)
The Delta Sky Club at DEN is on the mezzanine level of Concourse A near gate A39. The space includes complimentary food, a full bar, Wi-Fi, and shower suites. Delta runs DEN as a focus city rather than a hub, so the Sky Club here is mid-sized and not on the scale of the flagship clubs at JFK or ATL.
Access requires a same-day Delta boarding pass plus one of the following: Delta Sky Club membership, the Delta SkyMiles Reserve (15 visits per program year, unlimited with $75,000 spend), or the Amex Platinum (10 visits per year when flying Delta, unlimited with $75,000 spend). Basic Economy tickets are excluded.
The 3-hour pre-departure rule applies. Connecting passengers are exempt.
United Clubs (Concourse B)
DEN is one of United's largest hubs and the airport has three United Clubs, all on Concourse B. United Club B-East near gate B44 and United Club B-Center near gate B32 are the two larger locations, while United Club B-West near gate B17 serves the western end of the concourse. All three offer hot food, a full bar, shower suites, Wi-Fi, and quiet workspaces. The Center location was renovated most recently and is generally the best of the three.
Access is through United Club membership, the United Club Card (which includes membership), Star Alliance Gold status on a same-day international Star Alliance flight, United Polaris passengers, or a day pass starting around $59. The Chase United Quest and United Explorer cards do not include United Club access by themselves; they offer two annual one-time passes for the Quest and lounge access only on international Polaris flights.
DEN does not have a United Polaris Lounge. United Polaris passengers on international long-haul flights from DEN use the standard United Clubs.
Admirals Club (Concourse A)
The American Airlines Admirals Club at DEN is in Concourse A near gate A39. It is one of the smaller Admirals Clubs in the network and is generally quieter than the Capital One Lounge or Delta Sky Club a few gates away. Standard amenities apply: complimentary food, drinks, Wi-Fi, and showers.
Access is through Admirals Club membership, the Citi AAdvantage Executive (which includes membership for the primary cardholder), AA elite status on a same-day international itinerary, or a $79 day pass. American operates only a limited DEN schedule, so the lounge primarily serves connecting passengers.
USO at DEN
The USO Lounge at Denver International is on Level 5 of the Jeppesen Terminal and is free for active-duty military, retirees, and their families. It offers food, drinks, Wi-Fi, and a quiet space to rest before flights.
Priority Pass at DEN
Priority Pass coverage at DEN is limited compared to airports like DFW. Since Priority Pass ended its restaurant credit program in 2024, the dining options that used to count (Timberline Steaks & Grille, Grand Hyatt Pub 1144) no longer accept the membership. There is currently no traditional full-service Priority Pass lounge at DEN.
Cards that include Priority Pass: Amex Platinum, Chase Sapphire Reserve, Capital One Venture X, Hilton Aspire, Bilt Palladium.
If Priority Pass is your only lounge access at DEN, expect to fall back on the broader credit card airport lounge access guide for nearby airport options. For the strongest DEN lounge access, the Capital One or Centurion routes are the only meaningful paths.

Bottom Line
The Capital One Venture X is the strongest single card for lounge access at DEN. The Capital One Lounge on Concourse A is one of the best-designed in the network and the Venture X's $395 annual fee comes with a $300 travel credit and 10,000 anniversary miles, making the effective cost low. The Amex Platinum is the alternative if you fly Delta or want the new Centurion Lounge in Concourse C, but its $895 annual fee only makes sense if you use the broader travel credits. For frequent United flyers based in Denver, the United Club Card covers all three Concourse B clubs and is the most direct path to the gate.
