Ontario International Airport

Overview

Ontario International Airport (ONT) serves as the primary air gateway for Southern California’s rapidly growing Inland Empire region, covering San Bernardino and Riverside counties. It is a medium-sized, full-service airport that handles a mix of domestic passenger flights and substantial cargo operations. For travellers heading east of Los Angeles — or seeking a less congested alternative to LAX — ONT offers a streamlined experience with shorter lines and easier ground access. The airport also plays a critical role in global logistics, with major freight carriers like UPS and FedEx operating large hubs on site. While most flights are domestic, a handful of international routes connect to Mexico and Canada.

Location & Access

Ontario International Airport is situated approximately 35 miles east of downtown Los Angeles, within the city of Ontario, California. It lies just off Interstate 10, the major east–west freeway that links the region to Los Angeles, San Bernardino, and beyond. The airport’s address is 1923 E Avion Way, Ontario, CA 91761. Major nearby cities include San Bernardino (10 miles east), Riverside (15 miles southeast), Pomona (10 miles west), and Rancho Cucamonga (5 miles north). Driving is the most common way to reach the airport; the journey from downtown Los Angeles typically takes 40–60 minutes outside peak traffic. Ride-hailing services (Uber, Lyft) and taxis have dedicated pick-up zones at the terminal. Public transit options include Omnitrans bus routes that connect to the airport, and the Metrolink commuter rail station at East Ontario — roughly two miles away — with a shuttle service for rail passengers. For those driving, the airport offers several paid parking lots, including short-term, long-term, and economy options, with a free shuttle connecting the long- term lots to the terminal.

Facilities

The airport provides a range of amenities focused on accessibility and passenger convenience. The entire terminal — from the car park to the entrance and restrooms — is wheelchair accessible. Wheelchair rental is available on site, and baggage storage services allow travellers to store luggage for short or long periods. Free Wi-Fi is available throughout the terminal, with no login required. Restrooms are equipped with changing tables, making the airport family-friendly. A variety of on-site services include an information desk, lost and found, and assistance for travellers with disabilities. Parking is entirely paid, with multiple lots offering different rates. The terminal also features standard waiting areas, though specific shops, restaurants, and lounges are not listed among the confirmed amenities; visitors will find a limited but adequate selection of dining and retail options operating within the secure zone. Note that while the airport grounds are open daily, terminal access and TSA security checkpoint hours may vary, so passengers should confirm their flight’s operating schedule.

About the Region

The Inland Empire is one of the fastest-growing regions in the United States, known for its sprawling logistics and warehouse districts, affordable housing, and a booming distribution economy. Historically, the area was a centre for citrus farming, and remnants of that agricultural past remain in small groves and roadside stands. Today, the region is a critical hub for freight transport, with major rail yards and the nation’s largest concentration of warehouse space. For travellers, the Inland Empire offers a mix of business and leisure opportunities. Business visitors often come for the region’s industrial parks and corporate headquarters. Leisure travellers use the airport as a starting point for exploring the San Bernardino Mountains (skiing and hiking), Joshua Tree National Park (about 90 minutes east), or the desert resort city of Palm Springs. Closer to the airport, attractions include the Ontario Mills shopping mall, Toyota Arena for concerts and sports, and the historic Mission Inn in nearby Riverside. The climate is Mediterranean desert with hot, dry summers and mild winters, making the area a year-round destination for outdoor activities.
