Orlando International Airport (IATA: MCO, ICAO: KMCO) is a major international airport located 6 mi (9.7 km) southeast of the central business district of Orlando. It is the second-busiest airport in Florida, after Miami International Airport. It is the 13th-busiest airport in the United States and the 29th-busiest airport in the world by passenger traffic.The airport serves as a focus city for Southwest Airlines and JetBlue Airways. Southwest is currently the airport's largest carrier in terms of passengers traveled; in 2006, SWA carried one-fifth of MCO's passenger traffic.
The airport code MCO stands for the airport's former name, McCoy Air Force Base, a Strategic Air Command (SAC) base. Because KMCO is the largest major airport near Disney World, its code is sometimes jokingly described as "Mickey's Corporate Office."
