ONT Airport (Ontario International Airport) – Cargo, Address, Transit

About This Airport

The Inland Empire's warehouse economy is fed largely through Ontario International Airport (ONT/KONT), which handled about 618,000 tons of freight in the first nine months of 2025 and ranks among the busiest cargo airports in the United States. UPS Airlines runs an air hub on the field, and growth in 2025 came mainly from US mail — volumes more than doubled — while commercial freight slipped around 3.6%; full-year tonnage still finished 5.3% ahead of 2024. Unlike passenger-led airports, Ontario moves most of its tonnage on dedicated freighters, with belly capacity on domestic services as a supplement. Distribution centres in Ontario, Fontana and Riverside are typically within an hour's drive, and the container ports of Los Angeles and Long Beach lie roughly 90 km away, making sea-air and air-sea routings routine. Customs clearance is available on site for international arrivals. Los Angeles (LAX), about 85 km west, remains the alternative for intercontinental belly capacity, while San Bernardino (SBD) some 30 km away absorbs express volumes. For time-critical Asian imports, ONT often beats LAX on total door-to-door transit because the drayage leg into the warehouse belt is far shorter, even though it offers fewer direct services.
