President Trump's support of a $22.5 billion, 10-year renovation of Dulles International Airport in Loudoun County, Virginia is raising questions from industry observers about how the new debt will be serviced along with costs about existing outstanding bonds.
"Roughly doubling of airline cost per passenger at Dulles is already in MWAA's own published forecast before a dollar of the new program is added to it," said John Van Yperen, founder of the Aviation Financial Intelligence Database.
The Metropolitan Washington Airports Authority operates Dulles International Airport, which is about 25 miles east of downtown Washington D.C.
MWAA also operates Reagan National Airport, which is just across the Potomac river from the city and the Dulles Toll Road.
Airlines pay fees to airport authorities known as "cost per enplanement." CPEs can vary over time and according to industry sources, the current rate at Dulles is $12.77.
Forecasts from MWAA's Official Statement accompanying its 2025 $714.4 million bond sale will lead to CPEs rising to $20.71 by 2030.
Last year, CPEs at Los Angeles International were $33.85, Chicago O'Hare were $29.84 and $4.48 at Hartsfield Jackson in Atlanta.
Industry observer Edward Russel has postulated that financing a $22.5 billion renovation would translate into a $90 CPE at Dulles.
Dulles already had capital improvements teed up before the White House took an interest.
"The investment of more than $20 billion represents a significant increase over the $7 billion previously allocated for the Dulles International modernization program," said MWAA.
"The Airports Authority, working with airlines serving Dulles, will finance the new concourses and terminal facilities through municipal bonds, which offer significantly lower interest rates than bonds available to private-sector firms."
"Other portions of the new development will offer opportunities for public-private partnership investments."
MWAA operates Dulles and Reagan National Airport under a lease from Congress. It also operates the Dulles Toll Road which is owned by the state of Virginia.
"This new construction effort builds upon the multiyear Dulles Master Plan, developed in consultation with our airline partners, that will modernize Washington's main international airport," said MWAA president and CEO Jack Potter.
Dulles is a major hub for United Airlines, which is presumed to be bearing most of the costs for debt service.
The plan calls for 32,000 parking spaces, five million square feet of new or renovated space, including new and modernized concourses, an expanded main terminal with walkable access to gates, and new train service that will retire Dulles' "mobile lounge vehicles."
The mobile lounges or "people movers" are part of the airports original design by Finnish American architect Eero Saarinen.
They were intended to eliminate long walks to concourses. One of the lounges crashed last November, sending 18 people to the hospital.
The airport's new design was selected among 30 others and presented to the President by MWAA and United.
The plan has also been endorsed by Department of Transportation Secretary Sean Duffy and Va. Gov. Abigail Spanberger.
Dulles and Reagan National typically handle about similar numbers of passengers per year. By combining 2024 and 2025 the two airports accounted for over 53.9 million passengers.
"Significant growth in travelers at Dulles was enough to offset a slight decline in Reagan National passengers compared with its record-setting year in 2024," said MWAA.
Dulles recorded the highest rate of passenger growth among the nation's 50 largest airports in 2025, putting in 22nd place for the busiest airport. Atlanta, Ft. Worth and Chicago O'Hare are the top three.
