Ontario International Airport is located about 35 miles east of downtown Los Angeles, in Ontario, California. It has a modern terminal with multiple concourses handling domestic and some international flights. The airport offers a spread of shops, eateries and travel services designed to serve a mixed crowd of business and leisure travelers.

One of Ontario’s strongest appeals is the ease of navigation and often shorter security lines compared to LAX or other major hubs. However, some visitors note parking can be costly and road traffic congestion around the airport during peak hours can add significant time to journeys. The terminal layout is functional but less vibrant than larger airports.
