United Airlines is accelerating its $22.5 billion redevelopment of Washington Dulles (IAD), adding 5 million square feet of terminal space and new concourses to support 24% seat growth

## Summary

United Airlines is significantly expanding its hub at Washington Dulles International Airport (IAD) through a $22.5 billion redevelopment project, which has been accelerated to begin immediately following a July 29 agreement. The project aims to replace dated facilities like Concourse C-D and mobile lounges with a new master plan. Key components include:
- **Main Terminal and Concourse A**: Expansion of the iconic terminal, reconfigured ticket counters, a new connector to Concourse A, and a 14-16 gate extension.
- **AeroTrain and Tunnels**: Extension of the AeroTrain to new stations and a pedestrian tunnel linking the main terminal to all concourses.
- **Concourse E**: Full build-out of the first phase opening this fall, to be renamed Concourse C.
- **Concourse D**: A new domestic concourse south of the current Concourse E.
- **Concourse B**: A new regional concourse on the site of the current Concourse C-D. The redevelopment will add approximately 5 million square feet of terminal and concourse space. United's seat count at IAD is set to jump 24% this year compared to 2019, second only to its growth at Denver International Airport (DEN)
