Seattle to Boston Flights

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.

Boston Airport Information

Visitors to Boston usually fly into Logan International Airport, located roughly three miles across the harbor from downtown Boston. When you book flights to Boston through Orbitz.com, you will be able to choose from one of the many major domestic and international air passenger carriers that service the airport.

Ground Transportation in Boston

Logan Express bus service runs nonstop from Logan to Braintree, Framingham, Woburn and Peabody. For travel to all areas of Boston, take the MBTA's blue line subway service or silver line bus service. To get a view of Boston from the water, take the MBTA ferry to the commuter boat terminal in Quincy. A taxi from the airport to the downtown area should only cost you around $20, but if you have used Orbitz.com to book and purchase cheap tickets, your savings might be enough to warrant renting a car while you are there.

Boston Area Weather Information

Summers in Boston are beautiful, with average temperatures ranging from the mid-60s to the low 80s. Winters, however, can be brutal, with temperatures that can go from the low 20s to the mid-30s. When packing for your Boston trip, be sure to bring clothes that you can layer, and don't forget the warm jacket and snow boots if you plan to be there during the winter months.

Boston is a mecca for history buffs. The Paul Revere House, King's Chapel Burying Ground, Bunker Hill monument, Old North Church and Old South Meeting House are must-see attractions.
