What airport code does Chicago Midway have?

Chicago Midway International Airport is identified by the airport code MDW. This code is unique to Midway and is part of the International Civil Aviation Organization (ICAO) and International Air Transport Association (IATA) coding systems used for aviation purposes. Each major airport has its designated code which helps in the identification and operational processes at airports.

In this case, MDW directly corresponds to Chicago Midway, ensuring clarity and efficiency in booking, coordinating flights, and managing air traffic. The other codes mentioned—GSO (Piedmont Triad International Airport in Greensboro, North Carolina), HSV (Huntsville International Airport in Alabama), and MBJ (Sangster International Airport in Jamaica)—do not pertain to Chicago Midway, thus confirming that MDW is indeed the correct answer for this question.
