Travelers navigating the vast expanse of Southern California often find themselves at a crossroads when planning their flights. While Los Angeles International Airport (LAX) might be the first name that comes to mind, a significant and increasingly popular alternative serves the region: LA/Ontario International Airport (ONT). Often simply referred to as Ontario Airport, its precise location and strategic importance make it a critical gateway for millions.
Locating Southern California’s Inland Empire Gateway
LA/Ontario International Airport is situated in the city of Ontario, within San Bernardino County, California. This places it approximately 35 miles east of downtown Los Angeles, positioning it firmly within the expansive Inland Empire region. The Inland Empire, encompassing Riverside and San Bernardino counties, is one of the fastest-growing metropolitan areas in the United States, boasting a vibrant economy and a burgeoning population.

For many travelers, ONT offers a compelling alternative to the often-congested and sprawling LAX. Its location provides easier access for residents and visitors to the eastern and northern suburbs of Los Angeles, Orange County, and destinations further east such as Palm Springs or the mountain communities. The airport itself is modern, efficient, and typically offers a smoother travel experience with shorter lines and less traffic, making it a preferred choice for those prioritizing convenience and reduced stress.
The airport’s full name, LA/Ontario International Airport, reflects its dual identity: serving the immediate Inland Empire population while also acting as a crucial secondary international airport for the broader Los Angeles metropolitan area. This strategic position underscores its role not just as a local airport, but as a vital component of Southern California’s overall transportation infrastructure, easing the burden on other regional hubs and facilitating travel for millions.
Connectivity and Accessibility: Navigating To and From ONT
Accessibility is a cornerstone of ONT’s appeal. Its proximity to major freeway systems and various transportation options ensures that reaching the airport or departing from it is a relatively straightforward process, distinguishing it from the more complex logistical challenges sometimes associated with other large urban airports.
Road Networks
ONT is exceptionally well-connected to Southern California’s extensive freeway system. The Interstate 10 (I-10) freeway runs directly alongside the airport’s northern perimeter, providing a direct east-west artery. The Interstate 15 (I-15), a major north-south corridor, is just a few miles to the east, offering connections to Las Vegas and San Diego regions. Additionally, the State Route 60 (SR-60) freeway is easily accessible, linking the airport to other parts of the Inland Empire and Orange County.
Driving times to key areas are generally favorable:
- Downtown Los Angeles: 45-60 minutes (without heavy traffic).
- Orange County (e.g., Anaheim for Disneyland Park): 30-45 minutes.
- Riverside: 20-30 minutes.
- Palm Springs: 60-90 minutes.
- San Bernardino: 20-30 minutes.
The airport hosts a comprehensive array of major rental car companies within its consolidated rental car facility, easily accessible via free shuttle buses from the terminals. This centralized approach simplifies the process of picking up and dropping off vehicles, further enhancing the airport’s user-friendliness.
Public Transportation
While not as extensively connected by rail as some larger airports, ONT does offer public transportation options. Omnitrans, the public transit agency for San Bernardino County, operates several bus routes that connect the airport to nearby transit centers and cities like Ontario and Montclair.

For travelers heading towards Los Angeles or Orange County via rail, the Metrolink commuter rail service is an option. The closest Metrolink stations are in Ontario and Rancho Cucamonga, requiring a short bus or taxi connection to the airport. Plans are continually underway to improve direct transit access, including potential extensions of the Metrolink system or dedicated airport rail links, which would significantly enhance connectivity in the future.
Ride-Shares and Taxis
All major ride-sharing services like Uber and Lyft, as well as traditional taxi services, operate at ONT. Dedicated pick-up and drop-off zones are clearly marked outside both Terminals 2 and 4, ensuring efficient and organized service for travelers utilizing these popular options.
ONT as a Travel Hub: Destinations and Airlines
Over the past few years, LA/Ontario International Airport has experienced significant growth, transforming into a bustling travel hub for both domestic and international routes. Its success is a testament to its strategic location and the increasing demand for air travel within the Inland Empire.
The airport serves a wide array of airlines, offering competitive pricing and diverse route options. Major domestic carriers include Southwest Airlines, American Airlines, Delta Air Lines, United Airlines, Alaska Airlines, Frontier Airlines, Spirit Airlines, and JetBlue Airways. These airlines connect ONT to key cities across the United States, making it easy to reach destinations like Denver, Phoenix, Las Vegas, Dallas, Chicago, Seattle, Atlanta, and many others. The availability of multiple carriers often translates to more choices and better fares for travelers.
Beyond domestic flights, ONT has expanded its international footprint. Travelers can fly directly to Mexico City via Aeromexico, to Taipei with China Airlines, and to Panama City through Copa Airlines. These international connections are particularly valuable for business travelers and tourists alike, providing direct access to important global hubs without the need to transit through LAX. The international terminal at ONT is well-equipped to handle customs and immigration procedures efficiently, ensuring a smooth transition for arriving and departing passengers.
