Before 1974, the land the airport now sits on was largely owned by the United States Air Force who operated an airbase there. The base was known as McCoy Air Force Base and the civilian airport was known as the Orlando Jetport at McCoy. Commercial service to the Jetport began in 1962 as flights were migrated from the old Herndon Airport, now the Orlando Executive Airport. The airport was under control of the city of Orlando for just one year, and in 1975 the Greater Orlando Aviation Authority (GOAA) was founded. Their mission was to manage and build the Orlando International Airport and the Orlando Executive Airport. The airport gained its current name and international airport status a year later in 1976, but kept its old IATA airport code MCO and ICAO airport codeKMCO.
Eastern Airlines used Orlando as a hub during the 1970s and early 1980s, and became "the official airline of Walt Disney World." Following Eastern's demise, Delta Air Lines assumed this role, although it later pulled most of its large aircraft operations from Orlando and focused its service there on jet feederliner flights.
On February 22, 2005, MCO became the first airport in Florida to accept E-Pass and SunPass toll transponders as a form of payment for parking. The system allows drivers to enter and exit a parking garage without pulling a ticket or stopping to pay the parking fee.
Orlando International Airport has a single main terminal connected by people mover to four airside terminals. Airsides 1 and 2 use baggage claim "A", while airsides 3 and 4 use baggage claim "B."
