Overview
- Airport and United officials unveiled Concourse E on Monday and confirmed it will open to travelers Tuesday, Nov. 10, 2026, with regular passenger service beginning that day.
- The facility spans 435,000 square feet, includes 14 gates with jet bridges, direct AeroTrain access, upgraded restrooms and about 44,000 square feet of dining and retail space.
- Concourse E houses a nearly 40,000-square-foot United Club with seating for more than 600 customers, increasing United’s lounge space at Dulles by roughly 70 percent.
- United will use all 14 gates exclusively and says the extra capacity will let it push departures above 300 daily next summer and support new A321XLR transatlantic flights starting in December.
- The concourse cost about $745 million and is the first funded phase of the Dulles Global Gateway program, which leaders estimate will exceed $20 billion and may add up to 36 more gates, a customs facility and an AeroTrain extension in later phases.
