What is the airport code for Mexico City?

The airport code for Mexico City is MEX, which stands for "Benito Juárez International Airport." Each airport around the world is assigned a unique three-letter code by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA). MEX is specifically designated to identify the main international airport serving Mexico City, making it easy for travelers and airlines to refer to this airport in scheduling, ticketing, and check-in processes.

Options such as LIT, MEM, and MCO belong to different airports located in Little Rock (Arkansas), Memphis (Tennessee), and Orlando (Florida) respectively. These codes were created based on geographic and historical factors, but they are not related to Mexico City or its airport, which reinforces why MEX is the only correct choice in this context.
