Dulles International Airport could more than triple its annual passenger traffic by the 2080s under a sweeping new master plan that envisions additional gates, another runway and major commercial development.
The Metropolitan Washington Airports Authority board approved the plan July 16, sending it to the Federal Aviation Administration for review and concurrence. It is Dulles’ first new master plan in 40 years and looks more than half a century ahead.
The airport handled a record 27 million passengers in 2024. Its long-range target of 90 million represents an increase of about 230%, though officials have not set a firm deadline beyond an estimated 2080-to-2090 time frame.
MWAA Engineering Deputy Vice President Keith Autry described the plan as a flexible road map rather than a fixed construction schedule. Board Chair Thorn Pozen similarly acknowledged the uncertainty surrounding such distant projections.
Work on the 700-page plan began before the Covid pandemic, stalled during the public health crisis and later resumed. Its development also had to account for the opening of Metro’s Silver Line station, United Airlines’ expansion plans and a new agreement extending through 2039 with most carriers serving Dulles.
The airport’s recent rebound has been propelled by United’s growth and a sharp increase in international travel. Dulles currently operates 130 aircraft gates, including 79 used by United and 51 serving other airlines.
Under the plan’s projections, Dulles would reach 38 million annual passengers and 154 gates by 2040. Of those gates, 93 would serve United and 61 would accommodate other airlines.
Traffic is projected to climb to 45 million passengers by 2045 without another increase in gates. By the estimated 2080-to-2090 horizon, the airport could serve 90 million travelers through 218 gates.
The expansion sequence includes building, redeveloping and eventually demolishing terminals. AeroTrain service would be extended to a new Concourse F, planned for completion by 2040.
Concourse F would build upon the new United Airlines Concourse E now under construction. That facility is expected to open in late 2026.
A fifth runway is also included, although Autry said its timing and other decisions would depend on future traffic and airport needs. The plan additionally proposes upgrades to general aviation facilities, parking and roads throughout the airport.
Beyond aviation infrastructure, MWAA foresees mixed-use offices, stores, hotels and entertainment venues near Autopilot Drive. Light industrial development, potentially including data centers, could be added around the airport’s outer grounds.
The board’s approval came weeks after MWAA sold $714 million in capital bonds. About $410 million will finance new projects, while the rest will refinance debt issued in 2015.
Investors submitted $4.8 billion in bids during the June 5 offering. The bonds carried an average interest rate of 4.88%, which authority officials viewed as a strong reception despite volatile markets.
MWAA retained its existing ratings from the three major bond-rating firms: AA-minus from Fitch and S&P Global and Aa3 from Moody’s. All three assigned stable outlooks and found the authority’s growing debt burden manageable.
The sale closed July 10, with some of the new bonds extending to 2050.
