What happened
The Metropolitan Washington Airports Authority board unanimously approved a capital program under which Washington Dulles cannot retire its mobile lounges until a connector from the Saarinen terminal to Concourse A-B and an AeroTrain extension are finished in 2034. Those projects are part of the airport’s $19.9 billion redevelopment.
United gets new gates far sooner. A 14-gate section of Concourse E over the Concourse C AeroTrain station is scheduled for September and should be open to United passengers before the end of the year. It includes a 40,000 square-foot United Club. International arrivals will keep riding the lounges to customs until the later work is done.
Connecting and long-haul passengers at IAD, especially United customers, will keep using the mobile lounges well after the new gates and club open. Assume the mobile lounges remain through the mid-2030s and treat Concourse E later this year as the United upgrade to watch.
