Overview
- MWAA and United opened Concourse E to passengers on Tuesday, Nov. 10, 2026, delivering a 435,000-square-foot facility with 14 flexible gates and direct AeroTrain access.
- The concourse includes a nearly 40,000-square-foot United Club with seating for more than 600 people, increasing United’s lounge space at Dulles by roughly 70 percent.
- United says the added gates will let it scale operations toward about 300 daily departures next summer and support A321XLR transatlantic launches from Dulles to Amsterdam and Dublin in December 2026.
- Concourse E is the first phase of the Dulles Global Gateway program, a more-than-$20 billion multi‑phase modernization that will add dozens more gates, new customs processing and extended AeroTrain service over the coming years.
- Passengers gain more seating, upgraded restrooms, 44,000 square feet of dining and retail tenants, and reduced crowding at older temporary concourses, while long-term financing and airline charges will shape the pace and cost of future phases.
