Best terminal location (proposed)
The Ontario International Airport multimodal district. Ontario International Airport is the IE's airport — 7 million passengers a year and growing fast, with vast parking and cargo lands. A terminal integrated with the airport creates a true air-rail interchange, the model that makes European HSR work. The catchment is the IE's 4.7 million people, the airport's travelers, and the surrounding logistics workforce.
