Construction is moving along on United Airlines’ new concourse at Dulles International Airport, a 14-gate expansion that officials say will usher in a “new era of growth” for the D.C. region’s largest airline.
Expected to open in late 2026, the 435,000-square-foot Concourse E will directly connect to the airport’s underground Aerotrain station, add capacity for international flights and offer new amenities, including retail, concessions and a 40,000-square-foot United Club for the airline’s members.
