In addition to the airline terminal, several facilities at the airport serve the general aviation and corporate aviation community. General aviation operations outnumber commercial operations. The only other general aviation airport in Orange County is Fullerton Municipal Airport.
John Wayne Airport has two runways. The main runway, 2L/20R, at 5,701 feet (1,738 m) in length, is one of the shortest of any major airport in the United States, and passenger airliners at the airport have never been larger than the Boeing 757 (though some larger cargo aircraft fly from SNA, such as the FedEx A310/300). Runway 2R/20L is 2,887 feet (880 m) long and serves general aviation aircraft. No wide-body passenger airliners have ever been scheduled at SNA.
