Orlando Airport's official code is MCO, not OIA
Orlando International Airport's official code is MCO, not OIA. The airport was originally a military base called Pinecastle Army Airfield, which was constructed to serve the US military during World War II and the Korean War. In 1958, the airfield was renamed McCoy Air Force Base in honour of Colonel Michael Norman Wright McCoy, who died in a flight demonstration.
The airport gained its current name in 1976, a year after the McCoy Air Force Base was decommissioned and transformed into a civilian airport. Despite the name change, the airport code remained MCO, in tribute to Colonel McCoy. The airport's MCO designation is rooted in its military past, with the base name McCoy forming the basis of the code.
OIA is not a suitable alternative code for Orlando International Airport as it is already in use by another airport. OIA stands for Ourilândia do Norte Airport, an airport in Brazil that is now closed. Airport codes are designated by the International Air Transport Association, a trade group for the air travel industry that governs airport policies. Each three-letter designation is unique to an airport for convenience and ease of communication.
Orlando International Airport is one of the largest commercial airports in the United States in terms of land area, covering 47 square kilometres. It is also one of the busiest airports in the country, handling over 57 million passengers in 2022. The airport serves as a central hub for various airlines and is a major international gateway for the Florida region.

MCO derives from the airport's former name, McCoy Air Force Base
Orlando International Airport's IATA code is MCO, which is derived from the airport's former name, McCoy Air Force Base. The airport was originally constructed as a US Army Air Forces facility, and military operations began in 1942 as Orlando Army Air Field #2. In January 1943, it was renamed Pinecastle Army Airfield, serving as a crucial US military airfield during World War II and the Korean War.
In 1958, the airfield was renamed McCoy Air Force Base to honour Colonel Michael Norman Wright McCoy, a former pilot who died during a bombing and navigation competition. The airport transitioned to a civilian and military facility after the Vietnam War, gaining international status in 1976. Despite the name change, the airport code MCO was retained to commemorate Colonel McCoy.
McCoy Air Force Base was decommissioned in 1975 as part of a general military drawdown following the Vietnam War. The Greater Orlando Aviation Authority (GOAA) was then established to manage and oversee expansions to the airport, which became known as Orlando International Airport.
Today, Orlando International Airport is one of the largest commercial airports in the United States in terms of land area, covering 11,605 acres (4,696 hectares). It is a significant international gateway for Florida, serving over 170 domestic and international destinations. With its central location, the airport is within a two-hour drive of more than 60% of Florida's population, contributing to the region's dynamic economic growth.

McCoy Air Force Base was renamed in 1958 to honour Colonel Michael Norman Wright McCoy
Orlando International Airport, also known by the airport code MCO, was originally constructed as a U.S. Army Air Forces facility. Military operations began in 1942, and the airfield was initially named Orlando Army Air Field #2. In January 1943, it was renamed Pinecastle Army Airfield, and after the establishment of an independent U.S. Air Force in 1947, the airfield was briefly placed in caretaker status.
On 9 October 1957, Colonel McCoy was killed in the crash of a B-47 Stratojet of the 447th Bombardment Squadron, 321st Bombardment Wing. The aircraft suffered wing failure northwest of downtown Orlando while taking part in a practice demonstration during the annual Strategic Air Command Bombing Navigation and Reconnaissance Competition at Pinecastle Air Force Base. At the time of his death, McCoy was the commander of the 321st Bombardment Wing, and he was buried at Arlington National Cemetery.
In memory of Colonel McCoy, Pinecastle AFB was renamed McCoy Air Force Base on 7 May 1958. Formal dedication ceremonies were held on 21 May 1958, and an estimated 30,000 Floridians attended. The airport code MCO is derived from the former name of the airport, McCoy Air Force Base, and it continues to be recognised by this code today.
