The Orlando International Airport has a hub-and-spoke layout with a large main terminal building and four airside concourses accessible via elevated people movers, with a total of 129 gates.
The main terminal building is divided into two terminals; Terminal A (on the building's north side) and Terminal B (on the building's south side).
There are passenger check-in and baggage claim facilities in both terminals, which also share two security checkpoints, one in the West Hall leading to Airsides 1 & 3, and another in the East Atrium, leading to Airsides 2 & 4.
Unlike the similar setup used in Tampa, passengers are required to go through security before accessing the people movers.

Airsides 1 and 3, and later Airside 4, were designed by KBJ Architects, while Airside 2 was designed by Hellmuth, Obata and Kassabaum, Helman Hurley Charvat Peacock Architects, and Rhodes + Brito Architects.
C.T. Hsu + Associates and Rhodes + Brito Architects designed renovations that were made to Airsides 1 and 3, which were completed by April 2010.
