Which airport code is used for Orlando, Florida?

The airport code for Orlando, Florida, is indeed MCO, which stands for Orlando International Airport. This airport serves as the primary airport for international and domestic flights in the Orlando area, making it one of the busiest airports in Florida. MCO is derived from the airport’s previous name, McCoy Air Force Base, which it was built upon and renamed when it transitioned to a civilian facility.

The other codes provided refer to airports in different locations: PTY is the code for Tocumen International Airport in Panama City, Panama; CDG refers to Charles de Gaulle Airport in Paris, France; and PNS is the airport code for Pensacola International Airport in Pensacola, Florida. Each of these airports serves its own unique regions and does not relate to Orlando, thereby confirming MCO as the correct choice for this question.
