What is the most common airport ownership type in the U.S.?

Municipalities, including cities and counties, are the most common owners of airports in the United States. This ownership structure is prevalent because many airports serve as critical infrastructure for local communities, facilitating economic growth and providing essential transportation services. Local governments often manage airports to ensure they meet the community's needs, which can lead to enhanced regional connectivity and support for local businesses. This model allows for public funding and investment into airport facilities and operations, making them accessible and aligned with local transportation goals.

Private companies tend to own a smaller number of airports, often focusing on specific operational types like general aviation or niche services, while state and federal government ownership is less common due to the logistical complexities and scope of responsibility involved. These ownership types can influence airport management, funding, and operational priorities, making the municipality model a practical choice for the majority of airports in the U.S.
