Ontario International Airport (ONT) is a medium-hub, full-service airport with commercial jet service to major U.S. cities and through service to many international destinations. ONT is located in the Inland Empire, approximately 35 miles east of downtown Los Angeles in the center of Southern California. The airport is the centerpiece of one of the fastest-growing transportation regions in the United States. ONT's service area includes a population of six million people living in San Bernardino and Riverside Counties and portions of north Orange County and east Los Angeles County. In 2015 4.2 million passengers used the airport and 509,809 tons of air freight were shipped.
ONT's more than 64 daily flights provide service to major cities in the U.S. ONT's airlines include AeroMexico, Alaska, American, Delta, Southwest, United/United Express, and Volaris. The "new" Ontario International Airport opened September 27, 1998. The $270 million project includes two new terminals at 265,000 square foot each for a total of 530,000 square feet, a new ground transportation center, an additional parking lot and new roadway system, airfield improvements, landscaping, and a site storm-drain system. The new terminals are eight times larger than the former terminal and can accommodate up to 10 million passengers a year. When passenger traffic at ONT reaches 10 million in two consecutive years, a third terminal will be constructed.
ONT is also the center of a rapidly developing freight movement system that includes the airport, two railroads, four major freeways, and an expanding network of freight forwarders. ONT is served by major U.S. air freight carriers including Ameriflight, Empire Airlines, Federal Express, Kalitta Air, West Air and United Parcel Service. ONT is ideally situated as an airfreight center for Pacific Rim and European cargo. The airport is less than 50 miles from Los Angeles and Long Beach Harbors.”
