Book Your Flight from Seattle to Chicago

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.

Weather in Chicago

Summer temperatures in Chicago range from 66 to 84 degrees Fahrenheit, and the temperatures during the winter months range from 18 to 35 degrees Fahrenheit.
