On June 7, 1987, Washington Dulles International and Washington National Airports were transferred to the Airports Authority under a 50-year lease authorized by the Metropolitan Washington Airports Act of 1986. All property was transferred to the Airports Authority and the Federal government holds title to the lease. The Airports Authority operates a two-airport system that provides domestic and international air service for the mid-Atlantic region. The organization consists of more than 1,400 employees in a structure that includes central administration, airports management and operations, and police and fire departments. In addition to operating Reagan National and Dulles, the Airports Authority is responsible for capital improvements at both airports. The Airports Authority is not taxpayer-funded but is self-supporting, using aircraft landing fees, rents and revenues from concessions to fund operating expenses at both Airports. The Dulles Development Program is funded by bonds issued by the Authority, Federal and State Airport Improvement Program funds, and Passenger Facility Charges.
