Flights to Ontario

Seattle Airport

While Seattle is home to several airports, the only one that handles commercial flights is the Seattle-Tacoma International Airport. Also known as Sea-Tac, this airport is responsible for all incoming flights, along with flights from Seattle. Alaska Airlines, Air Canada, Delta Air Lines, Southwest Airlines, and US Airways are a few airlines that operate out of this airport. Located in SeaTac, Washington, the airport sits along the intersection of three state routes: 99, 518, and 509. Though the airport has three terminals, only the Concourse Terminal and North Satellite Terminal handle domestic flights. The South Satellite Terminal specializes in international flights. It's just a short drive from the airport to downtown.

Transportation

When you need to reach your hotel quickly, head for the public transportation system, which consists of Sound Transit and Metro Transit. The buses and light rails only cost a few dollars, and you can visit the sales counter at any station to purchase tickets for your trip. The light rail system drops passengers directly at some of the top hotels in the downtown area. Seattle uses a grid system for its roads, which makes finding your hotel easy if you drive. You can use the Orbitz.com sign to look for rental cars from the airport.

Weather

If you visit during the spring, winter, or fall, you need a warm coat and an umbrella. Though the city does not get snow, it does get a high amount of rain during these seasons, and temperatures that can drop below 40 degrees Fahrenheit. The summer is much warmer, with temperatures in the high 70s and less rainfall.

Popular Attractions

Seattle is home to dozens of cultural activities and attractions, including the Seattle International Film Festival, the Henry Art Galley, the Woodland Park Zoo, and the Seattle Underground Tour, which takes you through older parts of the city. When you look for flights from Seattle on Orbitz.com, take a few minutes to look for other low-cost attractions in the city.

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.
