In the United States, most commercial airports are owned by local or state governments (or regional "port authorities"), not the federal government. However, there are a few notable exceptions in 2026. The most prominent are Ronald Reagan Washington National (DCA) and Washington Dulles International (IAD); these are owned by the federal government but operated by the Metropolitan Washington Airports Authority (MWAA) under a long-term lease. Additionally, the Atlantic City International Airport (ACY) is owned by the South Jersey Transportation Authority but sits on land shared with the FAA's William J. Hughes Technical Center. Many smaller airfields on military bases or federal research sites (such as those owned by NASA or the Department of Energy) are also federally owned. Outside the U.S., many countries have moved away from federal ownership toward "privatization" or "semi-autonomous" state-owned corporations to increase efficiency and infrastructure investment in the post-2020 aviation recovery era.
