United Airlines opens new Concourse E at Washington Dulles Airport 

United Airlines and the Metropolitan Washington Airports Authority is set to open a new concourse at Washington Dulles International Airport (IAD) on November 10, 2026. 

The brand-new Concourse E, which is the first facility of this type to open at Washington Dulles International Airport in nearly two decades, was previewed on November 9, 2025, and will now be open to the public. 

This opening represents 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.  

The new United Club, which will be decorated with motifs inspired by the landmarks and sights of the US capital and its surrounding regions, will offer passengers 70% additional lounge space. 

United AirlinesUnited Airlines, which has Dulles Airport as one of its main US hubs, 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. 

As well as offering a more elevated experience to its passengers, the new Concourse E will also support the carrier’s further growth at the airport. This will include 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 which seeks to modernize Washington Dulles International Airport and bring the passenger experience it offers in line with contemporary standards. The airport revamp project is jointly backed by the Airports Authority, United Airlines, and the US Department of Transportation (DoT).
