Ontario International Airport (ONT) is a full-service commercial airport located in Ontario, California, approximately 35 miles east of downtown Los Angeles in the heart of the Inland Empire region. It serves as a convenient alternative to Los Angeles International Airport (LAX) for millions of residents in San Bernardino and Riverside counties. The airport was returned to local control in November 2016, when the Ontario International Airport Authority (OIAA) took over management from Los Angeles World Airports (LAWA). This transition marked a significant turning point, allowing the airport to pursue its own growth strategy independently. Since then, ONT has seen consistent passenger growth and expanded airline service. Ontario International handles both passenger and cargo operations, with its cargo facilities serving major logistics companies. The airport's strategic location near major freeways and distribution hubs makes it a critical node for air freight in Southern California.

The airport features two passenger terminals, Terminal 2 and Terminal 4, connected by a shared ticketing and baggage claim area, accommodating domestic and limited international flights.
