American Express Platinum and Centurion cardholders can use the Amex Centurion Lounge on Concourse C. Check current Amex terms and guest rules, and note the Centurion network's same-day-departure and entry-window policies before you rely on it.

American Express

The Capital One Lounge on Concourse C is open to eligible Capital One cardholders. Entry rules depend on your specific card; some cardholders get complimentary visits, while others can buy in. Confirm your card's current Capital One Lounge benefit before travelling.

Several Denver lounges sell paid entry on the day — the Capital One Lounge offers paid day passes alongside cardholder access, and United Club and Admirals Club day passes are available to eligible travellers. Buying ahead is usually cheaper and guards against capacity caps.

A premium-cabin or eligible international ticket on United, Delta or American gets you into that carrier's Denver lounge directly — the simplest route if you're flying a long-haul or transcontinental premium fare out of DEN, with no separate membership needed.

One terminal, three concourses

• —DEN has a single landside terminal (the Jeppesen Terminal) feeding three airside concourses, A, B and C — all lounges are airside.
• —An underground train connects the terminal to all three concourses; Concourse A is also reachable on foot via the pedestrian bridge.
• —Concourse C is the furthest from the terminal, so leave extra time if your lounge or gate is out there.

United is the big player

• —United operates its main hub here, with several United Clubs across Concourses A and B — its flagship is the Concourse B East lounge near Gate B44.
• —The Concourse B United Club has a mezzanine bar pouring local Colorado craft beer, a nod to Denver's brewery scene.
• —If you're flying United, match your lounge to your concourse rather than backtracking across the airport.

Card lounges as a route in

• —No airline status? The Amex Centurion and Capital One lounges on Concourse C give you a way in via an eligible credit card.
• —The Capital One Lounge opened in November 2023 and also sells paid day passes, useful if you don't hold the card.
• —Centurion access depends on same-day-departure and entry-window rules — check the current Amex policy before counting on it.

Timing & crowds

• —Denver is one of the busiest airports in the world and the lounges fill at the morning and late-afternoon United banks — arrive early for a seat.
• —The card lounges (Amex Centurion, Capital One) can hit capacity at peak and may hold a queue; build in buffer time.
• —Families travelling oneworld can use the Kids Zone at the Concourse C Admirals Club.
