The $20 Billion Airport Transformation Planned Around United's Washington Hub
Dulles just tripled its modernization budget to more than $20 billion, with Concourse C and D set for replacement.
The Metropolitan Washington Airports Authority (MWAA), United Airlines, and the US Department of Transportation unveiled a capital investment plan worth more than $20 billion for Washington Dulles International Airport (IAD). The announcement outlines a wide-scale program spanning the next decade.
The project encompasses more than 5 million square feet (464,515 square meters) of new or renovated space as part of the effort. It is described as roughly tripling the $7 billion modernization outlined in MWAA’s master plan from May 2025.
A key element of the plan is the retention of Eero Saarinen’s Main Terminal, which will remain in place. In contrast, Concourse C and D, which host a central portion of United’s hub operations, are slated for replacement.
The collaboration between MWAA, United Airlines, and the Department of Transportation focuses on transforming facilities linked to United’s hub at IAD, with the long-term goal of enhancing capacity and operations across the airport.
No specific dates beyond the decade-long scope are provided in the announcement, and no details on potential impacts to passengers, construction phasing, or rollout timelines are included in the supplied material.
