United Airlines and the Metropolitan Washington Airports Authority opened a new concourse at Washington Dulles International Airport (IAD) on November 10, 2026. The brand-new Concourse E is the first facility of this type to open at Washington Dulles in nearly two decades. The opening marks the completion of the first of four construction stages, which will see Concourse E fully replacing the existing Concourse C/D.
The first stage includes a new 435,000-square-foot facility with 14 boarding gates, which will be used by United Airlines. Passengers using the new terminal will also be able to enjoy direct AeroTrain access, new dining and retail options, and a state-of-the-art, 40,000-square-foot United Club lounge, which will offer passengers 70% additional lounge space and is decorated with motifs inspired by the landmarks and sights of the US capital and its surrounding regions. United will see another 36 gates added at a future stage, as well as one of the world's largest Polaris lounges and an expanded customs processing area.
The new Concourse E will also support the carrier's further growth at the airport, including the launch of several new European destinations operated with the carrier's new Airbus A321XLR aircraft, such as Amsterdam (AMS) and Dublin (DUB) in December 2026, and Toulouse (TLS) and Milan (MXP) at a later date. The opening marks an important milestone in an ongoing $20 billion program to modernize Washington Dulles International Airport, jointly backed by the Airports Authority, United Airlines and the US Department of Transportation.
