Ontario International Airport – 5700 Airport Drive, Ontario, California

Ontario International Airport (IATA: ONT, FAA: ONT) is a full-service commercial airport located at 5700 Airport Drive in Ontario, California, serving the Inland Empire region of Southern California. Situated approximately 35 miles east of downtown Los Angeles and 23 miles west of San Bernardino, ONT occupies a strategic position in one of the nation's fastest-growing metropolitan corridors. The airport covers roughly 1,600 acres and operates two parallel runways — Runway 08L/26R at 12,198 feet and Runway 08R/26L at 10,200 feet — capable of handling wide-body international aircraft including the Boeing 747 and Airbus A380.

The facility is managed by the Ontario International Airport Authority (OIAA), an independent authority established in 2016 when the City of Ontario and the County of San Bernardino reclaimed operational control from Los Angeles World Airports (LAWA). Since regaining local governance, ONT has undergone significant investment in infrastructure, passenger experience, and air service development. The airport's two terminals — Terminal 2 and Terminal 4 — collectively offer over 25 gates and have been modernized with upgraded concessions, expanded seating, and enhanced security checkpoints operated in coordination with the Transportation Security Administration.

Ontario International handled approximately 5.8 million passengers in 2023, reflecting continued recovery and growth following the pandemic-era travel disruptions. The airport serves as a key alternative to Los Angeles International Airport (LAX) and John Wayne Airport (SNA), offering shorter security lines, closer parking, and easier ground access via Interstate 10, Interstate 15, and State Route 60. Business and leisure travelers from communities including Riverside, San Bernardino, Rancho Cucamonga, Fontana, and Corona routinely choose ONT for its convenience.

Airlines operating at Ontario International include American Airlines, Delta Air Lines, Southwest Airlines, United Airlines, Alaska Airlines, Frontier Airlines, and Volaris, among others. Nonstop service connects ONT to major hubs such as Dallas/Fort Worth (DFW), Denver (DEN), Seattle-Tacoma (SEA), Chicago O'Hare (ORD), Atlanta (ATL), and Phoenix Sky Harbor (PHX), as well as key leisure markets including Las Vegas (LAS), Cancún (CUN), and Mexico City (MEX). Cargo operations are equally robust, with UPS, FedEx, and Amazon Air maintaining significant freight activity that supports the dense logistics and warehousing sector in the Inland Empire.

Ground transportation from 5700 Airport Drive includes the ONT Airport Connector, a free shuttle linking the terminals to the Ontario-East (Milliken Avenue) station of the Metrolink San Bernardino Line, providing rail access toward Los Angeles Union Station. Rideshare services from Uber and Lyft operate from designated curb zones on the lower level of each terminal. Multiple rental car companies — Hertz, Avis, Budget, Enterprise, National, Alamo, and Dollar — operate from the on-airport Consolidated Rent-A-Car facility accessible by shuttle. Long-term and short-term parking structures adjoin both terminals, with rates structured to remain competitive with regional alternatives.

For travelers connecting through Southern California's broader airport network, Ontario sits within reasonable driving distance of several general aviation facilities. Livermore Municipal Airport (LVK) lies roughly 375 miles north via I-5, while Meadowlark Airport in Huntington Beach is approximately 45 miles southwest near the Orange County coast. Clean Energy Oakland International Airport (OAK) and Oakland Airport Security operations are accessible from Northern California, serving as alternative Bay Area gateways. Direct Airport Shuttle provides scheduled shared-ride ground transportation linking Ontario with surrounding Inland Empire communities, LAX, and select Orange County destinations.

The Ontario International Airport Authority continues to pursue long-term master planning initiatives aimed at increasing annual passenger capacity to 12 million and expanding international service. Terminal improvements, a proposed consolidated hotel, and enhanced cargo infrastructure are among the priority projects under review. The airport's location in San Bernardino County — one of the largest counties by area in the contiguous United States — positions it as a critical node in Southern California's aviation and logistics ecosystem for decades ahead.
