Washington Dulles has 12 lounges spread across a Main Terminal and 4 concourses, and as of mid-2026, no single credit card covers all of them. There's no Centurion Lounge, no Delta Sky Club, and no Admirals Club here, which is unusual for an airport this size. What IAD does have is a brand-new Chase Sapphire Lounge, a Capital One Lounge currently running on reduced service, and one of the best United Polaris Lounges in the network.
The result rewards knowing exactly which card to bring, rather than defaulting to whichever premium card you already carry. Here's every lounge at IAD, organized by concourse, with the cards that get you in and what's actually open right now.
IAD Terminal and Concourse Layout
Dulles operates one Main Terminal, the Eero Saarinen-designed building where you check in and clear security, plus 4 airside concourses: A, B, C, and D. A fifth concourse, E, is under construction and set to open in fall 2026 with a 40,000-square-foot United Club, one of the largest in North America.
The AeroTrain, an underground automated train, connects the Main Terminal to Concourses A, B, and C, with each hop taking about 2 minutes. Concourses C and D connect to each other on foot. All of these transfers stay inside the secure zone, so you can clear security once and reach any lounge in any concourse without a second screening.
Capital One Lounge (Main Terminal)
The Capital One Lounge sits in the Main Terminal, immediately past TSA PreCheck, open daily from 5:30 AM to 9 PM. In normal operation it's a full-service space with an espresso bar, in-house dining, a stocked bar, a parents room, semiprivate workspaces, and luggage lockers.
As of July 9, 2026, the lounge is running a limited-service model while it completes infrastructure and ventilation upgrades. Seating and the full bar are unavailable; you get grab-and-go dishes and a coffee cart with some outdoor-adjacent seating in the terminal. Capital One has said full service should return in early fall 2026.
Access requires a Capital One Venture X card for unlimited entry, or a Venture card at $45 per visit. Day passes run $65. Since February 1, 2026, guests are no longer automatically complimentary: primary cardholders need $75,000 or more in calendar-year Venture X spend to bring 2 free guests, otherwise each additional guest costs $45 ($25 for guests under 17).
The Chase Sapphire Lounge (Concourse A)
The single biggest change at IAD this year is the Chase Sapphire Reserve lounge in Concourse A near Gate A14. What used to be a standalone Etihad Airways lounge relaunched in March 2026 as the Chase Sapphire Lounge by The Club, a joint operation between Chase and Etihad. At 5,200 square feet, it's smaller than Chase's flagship locations but carries the same format: a buffet, full table-service dining, signature cocktails, showers, a family room, and a prayer room. Hours are 6 AM to 10 PM daily.
Chase Sapphire Reserve cardholders (along with J.P. Morgan Reserve and Ritz-Carlton cardholders) get unlimited access and up to 2 complimentary guests per visit, once Priority Pass is activated on the account. That's a meaningfully better guest policy than the Capital One Lounge's current $45-per-guest structure. Priority Pass members who don't carry one of those 3 cards are capped at one visit per calendar year at any US Chase Sapphire Lounge location, subject to availability, with extra visits priced at $75.
United Polaris Lounge and United Clubs (Concourses C and D)
Dulles is a major United hub, and it shows in Concourse C. The United Polaris Lounge sits near Gate C17, open roughly 5:30 AM to 10 PM, with 6 shower suites, 2 quiet rooms, and a dining room that seats 42 for full table-service meals. Access is strictly ticketed: United Polaris business class or international first/business class on a Star Alliance partner. No credit card grants direct entry, matching the pattern at every other Polaris Lounge in the network.
Below the Polaris tier, United operates 3 United Clubs at Dulles: one near Gate C7, one near Gate C17 (in the same complex as Polaris), and one near Gate D8, all generally open 5:30 AM to 10 PM. The United Club Infinite Card covers all 3, as does a $59 day pass, United Club membership ($750 to $1,400 a year), a same-day Polaris or United Business ticket, or United/Star Alliance Gold status and above. When Concourse E opens in fall 2026, a fourth club joins the lineup at 40,000 square feet, more than double the size of the current locations combined.
Priority Pass at Dulles
With no Centurion Lounge and no Delta Sky Club, Priority Pass carries more weight at IAD than at most hub airports. Three lounges accept it, and one of them, the Turkish Airlines Lounge, is regularly ranked among the best Priority Pass lounges in the country.
| Lounge | Concourse | Hours | Priority Pass Terms |
|---|---|---|---|
| Turkish Airlines Lounge | B, near Gate B43 | 7:30 AM–10 PM | Full access, 3-hour max stay |
| Air France-KLM Lounge | A, near Gate A19 | 7:30 AM–9 PM | Full access, 3-hour max stay |
| British Airways Galleries Lounge | B, opposite Gate B50 | 2:30 PM–10:30 PM | Full access, 3-hour max stay |
| Chase Sapphire Lounge | A, near Gate A14 | 6 AM–10 PM | 1 visit/year unless CSR, extra visits $75 |
Cards that carry Priority Pass here include the Amex Platinum, Chase Sapphire Reserve, Capital One Venture X, and Hilton Aspire. For the full national list of which cards include the membership, see which credit cards offer Priority Pass.
Lounges Not Currently Available
The Lufthansa Business and Senator Lounges in Concourse B, near Gates B49 through B51, are closed for an extensive renovation running from October 2025 through the end of 2026. The Virgin Atlantic Clubhouse in Terminal A, opposite Gate A32, is also temporarily closed as of this writing. Neither closure affects Priority Pass coverage, since both were ticket- and status-gated rather than card-accessible to begin with.
Credit Card Lounge Access Summary
| Card | Lounges at IAD |
|---|---|
| Chase Sapphire Reserve | Chase Sapphire Lounge (A, unlimited + 2 guests), Turkish Airlines + Air France-KLM + BA Galleries via Priority Pass |
| Capital One Venture X | Capital One Lounge (Main Terminal, limited service through early fall 2026), Turkish Airlines + Air France-KLM + BA Galleries via Priority Pass |
| Amex Platinum | Turkish Airlines + Air France-KLM + BA Galleries via Priority Pass, 1 visit/year at Chase Sapphire Lounge |
| United Club Infinite Card | 3 United Clubs (C7, C17, D8), 4th opening in Concourse E fall 2026 |
| Hilton Aspire | Turkish Airlines + Air France-KLM + BA Galleries via Priority Pass, 1 visit/year at Chase Sapphire Lounge |

Bottom Line
The Chase Sapphire Reserve is the strongest single card at IAD today, largely because its dedicated lounge is new, unlimited, and includes 2 free guests, while the Capital One Lounge works through a multi-month service reduction. That edge narrows once Capital One's renovation wraps in early fall 2026 and the two lounges compete on equal footing. United loyalists should still reach for the United Club Infinite Card, since 3 clubs plus a fourth on the way in Concourse E cover more ground than any Priority Pass card can. The Card Advisor can weigh the $795 Sapphire Reserve fee against your actual travel and spending patterns to confirm it's the right pick before you apply.
