The Metropolitan Washington Airports Authority (MWAA) is an independent airport authority, created with the consent of the United States Congress to oversee management, operations, and capital development of the two major airports serving the U.S. national capital: Ronald Reagan Washington National Airport and Dulles International Airport. The Airports Authority was established to operate as a financially self-sustaining entity with the mission to manage and enhance Washington, D.C.'s two-airport system. The authority leases the airports from the United States Department of Transportation. The U.S. government originally built the airports and continues to own the underlying airport property except for property acquired by MWAA subsequent to the lease.
