Orlando International Airport (MCO) is the busiest airport in Florida and one of the busiest in the United States, consistently handling over 50 million passengers annually in pre-pandemic years. It serves as a major gateway for tourists visiting Walt Disney World, Universal Studios, SeaWorld, and other Central Florida attractions. The airport is operated by the Greater Orlando Aviation Authority and features a unique landside-airside terminal design connected by an automated people mover system. A major expansion, Terminal C, opened in September 2022, significantly increasing the airport's capacity and international handling capabilities. MCO's IATA code traces back to its former identity as McCoy Air Force Base, which closed in 1975 and was converted to civilian aviation use. Its central Florida location and extensive route network make it one of the most visited airports in the country.
