Yes, Orlando International Airport and MCO are the exact same facility. MCO is the three-letter IATA (International Air Transport Association) code for the airport. Interestingly, the code "MCO" stands for McCoy Air Force Base, which occupied the site until the mid-1970s before it was converted into the commercial gateway we know today. In 2026, MCO remains the primary hub for travelers visiting Disney World and Universal Studios. It is famous for its multi-terminal layout, including the ultra-modern Terminal C, and its iconic monorail shuttles (APMs) that transport passengers from the main landside hub to the individual airside gates. When booking flights to Orlando, always ensure you are selecting MCO to avoid confusion with the much smaller Orlando Sanford International Airport (SFB).
