DEN Airport Lounges by Concourse: Hours and Who Gets In

DEN has lounges on all three concourses. The airport's dining directory lists them, with the gate each is nearest:

• Concourse A: Capital One Lounge (Plaza Premium) near gate A-34 on the mezzanine, daily 5 a.m. to 9 p.m.; Delta Sky Club on Level 4, north side of Center Core, daily 4:15 a.m. to 0:15 a.m. as listed; United Club A West near gate A-25, daily 5 a.m. to 8:30 p.m.
• Concourse B: United Club B East near gate B44, daily 5 a.m. to 9 p.m.; United Club B West near gate B32, daily 5 a.m. to 9 p.m.; United Club Fly B East near gate B-60, daily 7 a.m. to 8 p.m.
• Concourse C: American Airlines Admirals Club near gate C-30 on the mezzanine, daily 4:30 a.m. to 11:30 p.m.; American Express Centurion Lounge on the mezzanine between gates C46 and C48, daily 5 a.m. to 10 p.m.
• Jeppesen Terminal: no lounge listed.

The Delta Sky Club hours print as 4:15 a.m. to 0:15 a.m. in the directory. That most likely means closing just after midnight, so confirm on delta.com or in the Fly Delta app.

United runs the most lounges at DEN: three clubs plus United Club Fly.

• United Club B East (near gate B44) is the biggest. DEN's page says it has 35,000 sq. ft. across three levels and more than 600 seats, which United calls the largest club in its network. It has a mezzanine feature bar with 10 local and craft beers on tap, free high-speed Wi-Fi, self-scan entry gates, agent kiosks and wellness rooms.
• United Club A West (near gate A-25) is a 24,000 sq. ft. club with two premium bars and 400 seats across two levels, a game lounge with shuffleboard and two fireplace lounges.
• United Club B West (near gate B32) and United Club Fly (near gate B-60) are listed with hours only. For access rules and day-pass prices on any United club, check united.com or the United app.

American's Admirals Club is on Concourse C on the mezzanine level near gate C-30, daily 4:30 a.m. to 11:30 p.m. DEN's page lists a phone number for the club, (800) 237-7971, and says it offers PCs with internet access, complimentary Wi-Fi, food for purchase and conference rooms.

British Airways passengers in Club World, and Gold and Silver Executive Club members, can use the Admirals Club (and the United Club on Concourse A) when departing on flight BA218 to London Heathrow, according to DEN's pages.

For Admirals Club day-pass prices and membership rules, check aa.com.

• American Express Centurion Lounge: Concourse C, on the mezzanine between gates C46 and C48 (take the escalators up), daily 5 a.m. to 10 p.m. per DEN's directory. American Express says access is not guaranteed and depends on space, and visitors must be 18 or older unless with an adult. American Express lists the lounge for Delta SkyMiles Reserve Card members; check your card's terms on americanexpress.com for guests, fees and arrival windows.
• Capital One Lounge (Plaza Premium): Concourse A, on the mezzanine near gate A-34, daily 5 a.m. to 9 p.m. Check capitalone.com for who gets in and what guests pay.
• Delta Sky Club: Concourse A, Level 4, north side of Center Core. Delta says Reserve Card members get 15 visits each Medallion Year, and Executive Membership allows up to two guests. Delta does not publish a walk-in price on that page, so check delta.com before you plan on buying entry.

Chase Sapphire Lounge: as of October 9, 2026, Chase's lounge page does not list Denver among its open or coming Sapphire lounges.

Priority Pass lists two Denver spots, both on Concourse A, on its Denver International Airport page:

• Mercantile Dining and Provision, 6:00 a.m. to midnight, listed under dining with a restaurant voucher.
• Golf DEN, 7:00 a.m. to 7:00 p.m., a play-and-reset space.

DEN's directory puts Mercantile Dining & Provision in the Center Core and Golf DEN on the Center Core Mezzanine Level, west side. For voucher value, visit limits and guest rules, check your Priority Pass app. Priority Pass does not list a traditional lounge at DEN.

DEN's pages list no prices for any lounge, and the Delta and American Express lounge pages show no Denver walk-in price. Do not count on buying a walk-in pass without checking first.

What to do: check the airline's or card issuer's lounge page for your lounge, or ask at the lounge desk. Amex says Centurion access depends on space, so arrive with a backup plan.

If you have no lounge access, DEN lists a few other places to relax.

• Rest & Recharge Area: Concourse A, Mezzanine Level, north side, always open.
• USO Denver: Concourse A, Level 4, above the Mezzanine Level of the center of Concourse A, daily 7 a.m. to 7 p.m. DEN's directory does not say who can use it, so ask at the desk or check uso.org.
• Sky Lounge: this is a bar at the Westin Denver International Airport hotel, Level 6, daily 3 p.m. to 12 a.m. It is in the hotel, not an airline or card lounge.

Concourse C is a train ride from the terminal, and so is B. Concourse A has the post-security walkway, 1,100 feet above the taxiway, that DEN describes as a good alternative to the train for passengers on all A gates.

If your lounge is on A, plan for the walkway or the train. If it is on B or C, take the train from the terminal after security.
