Ontario International Airport (ONT), one of the fastest growing airports in the country, is expected to play a significant role for the economic development of the Inland Empire. Two identical terminals were designed, each with capacity to handle five million passengers annually, mitigating demand imposed upon Los Angeles International Airport (LAX).

JGM, in conjunction with a local firm, was responsible for terminal design and planning, as well as on-site construction administration. The design consists of a linear structure effectively utilizing the narrow north/south site parallel to the airfield and allowing the integration of a single level roadway and double-level terminal. Alternating enplaning and deplaning functions are extended over the entire length of the terminal area, resulting in added convenience for commuters and flexibility for airline operations.

The Master Plan includes space to build two more terminals and improved cargo facilities. Designed for efficiency, imageability and constructability, the Ontario Terminals were completed ahead of schedule and under budget.
