Flying Into Ontario International Airport

Flights into Ontario International Airport are for passengers destined for the Inland Empire region of California. Located 35 miles from downtown Los Angeles on East Airport Drive, the airport is actually a part of the LAX system. A medium-sized hub, the airport has the capabilities to service a full slate of commercial flights. Airlines found within the terminals include international carriers Aero Mexico as well as popular domestic carriers like United, Southwest, Delta and American Airlines. Seven airlines service LA/Ontario International, and they operate more than 114 flights each day.

Finding Transportation From the Airport

There are several ways to get to the many cities throughout the Inland Empire region. Hotels in and around Ontario offer hotel shuttles, free of charge, that run from the terminal to the hotel lobby. You can take a taxi to downtown Ontario for a little more than $10 or go all the way to downtown Los Angeles for around $100. Private shuttles are also available and will cost about the same fees. Private shuttles, however, must be reserved. Rental cars are also available. With Orbitz.com, you can buy tickets and reserve a rental car at the same time.

What to Expect From the Weather

The weather is always sunny. The temperatures rarely dip below 70 degrees Fahrenheit and are usually below 90 degrees Fahrenheit. Temperatures in July and August may exceed this range, but never stick around for long. Don't expect the threat of rain to ruin your plans or dictate the calendar when booking tickets on Orbitz.com.

Ontario's Offerings for Visitors

When in Ontario, check out the outdoors in Cucamonga-Guasti Regional Park. You can also take in a concert at the Ontario Convention center or have a cultural experience at the Museum of History and Art, Ontario. Don't just race through the city on your way to Los Angeles or the surrounding cities. Booking bargain flights to Ontario with Orbitz.com will save you some major cash, so spend it exploring what the city has to offer.
