- A public airport is an airport that is open to the public for usage and operated by a government agency or authority. These airports provide services to the general public, including domestic and international flights. Public airports are usually funded by government investments and generate revenue through various sources, such as landing fees, passenger facility charges, and concessions. They play a crucial role in facilitating the movement of people and goods, as well as contributing to the local economy through job creation and tourism. Examples of public airports include John F. Kennedy International Airport in New York City, Charles de Gaulle Airport in Paris, and Sydney Airport in Australia.
