Airlines at a growing Dulles International Airport will see higher operating costs in 2026 under a new budget adopted Nov. 19 by the Metropolitan Washington Airports Authority (MWAA).
The $889.5 million package, adopted unanimously by the authority’s board of directors, estimates that the “cost per enplanement” at Dulles will rise from the $11.17 budgeted in 2025 to $12.77 in 2026 — an increase of about 14%.
