The Southwest Terminal MCO is located in Terminal A , specifically in Airside 1 . Orlando International Airport is divided into two main airsides: Airside 1 (Terminal A) and Airside 2 (Terminal B). Southwest Airlines operates exclusively from Airside 1, which is easily accessible from the main terminal via the airport's automated people mover system. This system, known as the Hyatt Regency Orlando International Airport People Mover , connects the main terminal to both airsides, making it quick and convenient to reach your gate.
