Denver International Airport serves as a major United Airlines hub and a key connecting point for travelers across the western United States. With lounges spread across Concourses A, B, and C, frequent flyers with tight connections need a clear transfer timing checklist to know which lounges are accessible and how much time to budget. Here is the DEN lounge landscape and the transfer timing variables for 2026.
The United Club operates three locations at DEN, with the largest in Concourse B West near gate B32 and a second in Concourse B East near gate B44. A smaller United Club operates in Concourse A. The American Express Centurion Lounge is in Concourse C near gate C46, accessible post-security. The Capital One Lounge is located in Concourse A on the mezzanine level. Delta Sky Club operates in Concourse A near gate A25.
Concourse A is accessible from the main terminal via the underground train, while Concourses B and C are further along the same train line. Walking between concourses is possible via the bridge at the mezzanine level between A and B, but moving from B to C or A to C requires the train or significant walking time.
For a thirty-minute connection at DEN, skip the lounge entirely and proceed directly to your departure gate. The United Clubs in B are your only realistic option for connections of forty-five to sixty minutes if you are flying United and your gates are near the lounge. The Centurion Lounge and Capital One Lounge require at least one hour between flights to be usable, factoring in train transit time and lounge check-in queues during peak afternoon hours.
For a seventy-five to ninety-minute connection, the Centurion Lounge in C and Capital One Lounge in A become feasible. Budget ten to fifteen minutes each way for train transit from B to C or A to B. Peak times between two p.m. and six p.m. see the longest Centurion Lounge waitlists, so build in extra margin if traveling during those windows.
If your connection exceeds two hours, all DEN lounges are within reach regardless of departure concourse. Use the extra time to sample the Capital One Lounge grab-and-go options for a quick bite before settling into another lounge closer to your gate.
United Club access requires a same-day United boarding pass and either a United Club membership, one-time pass, or eligible premium cabin or Star Alliance Gold status. Centurion Lounge access requires an American Express Platinum or Centurion card and a same-day boarding pass. Capital One Lounge access is available to Venture X cardholders with a same-day boarding pass, and Delta Sky Club access follows Delta’s published access policies including eligible credit cards and premium cabin tickets.
This checklist reflects lounge locations, access policies, and transfer logistics at Denver International Airport as of July 2026. Lounge access rules and operating hours are subject to change. Confirm current details before travel.
Q: Which DEN lounge has the best food? A: The Centurion Lounge and Capital One Lounge generally offer superior food and beverage quality compared to United Clubs, with the Capital One Lounge featuring a tapas-style menu and craft cocktails.
Q: Can I access multiple lounges during a long connection? A: Yes, with the right access credentials, you can visit multiple lounges. The Centurion Lounge and Capital One Lounge are in different concourses, so plan train transit time accordingly.
