Overview
- The 435,000-square-foot Concourse E opened to travelers on Tuesday, Nov. 10, 2026, and provides 14 new United gates with direct access to the airport’s AeroTrain.
- Concourse E houses a nearly 40,000-square-foot United Club with seating for more than 600 people, increasing United’s lounge space at Dulles by about 70 percent and improving passenger seating, power access and retail options.
- Each new gate can handle one widebody or two narrowbodies so United can mix domestic and international flights, and the airline plans A321XLR service from Dulles to Amsterdam and Dublin beginning in December 2026 with further long-haul routes planned for 2027.
- Concourse E is the first of four planned phases in the Dulles Global Gateway program, which will add more gates, a new U.S. customs processing facility and an AeroTrain extension while C and D replacements remain dependent on later construction and financing.
- The project relieves current crowding at United’s older gates but will be financed mainly with airport bonds and airline charges, a shift MWAA warns could raise carrier costs per departing passenger over time and change long-term airport economics.
