- A civil airport is an airport that caters to civilian air traffic. It is open to the general public and serves as a gateway for passengers traveling by air to various destinations. Civil airports are typically operated by government authorities or private entities and offer services such as terminal buildings, runways, parking areas, and other facilities required for the safe and efficient operation of civil aviation. They can provide domestic and international flights, serve as hubs for multiple airlines, and handle various types of aircraft, including commercial airliners, private jets, and general aviation aircraft. Examples of well-known civil airports include London Heathrow Airport, Los Angeles International Airport, and Singapore Changi Airport.
