Before diving into the specifics of the MCO frontier terminal, it’s helpful to understand the structure of Orlando International Airport. MCO is unique in its layout, consisting of a main terminal building (called the Landside Terminal) and four airside concourses — Airside A, B, C, and D. Each airside terminal houses a specific set of gates and is connected to the main terminal via an automated people mover (APM), a type of monorail system.
