Cheap flights from Boston to Seattle

Seattle is a great city to explore, and having a vehicle at your disposal makes it easier to get to all the fun venues. After picking up your keys at the car rental desk at the Seattle-Tacoma International Airport (SEA), you can drive to one of the many local coffee shops that make this city their corporate headquarters. When the caffeine buzz kicks in, it's time to make your way downtown and begin exploring the city.

Key Facts

One of your first stops should be Pike Place Market to enjoy the flying fish. At this local market, fishermen bring in the catch of the day and sell it directly to you off the boat. As part of the fun, workers toss the fish through the air from one to another before wrapping it to go. Make sure to get a picture with the famous bronze pig to add to your scrapbook. For amazing views of the whole city, visit the observation deck of the Space Needle, or head to Kerry Park on Queen Anne.

Hints and Tips

Your flying time from Boston's Logan Airport (BOS) to Seattle is just shy of six hours. Upon arrival, you'll find the Seattle Airport serves as a hub for many people making connections to other locations. If you are traveling on from this airport, make sure you visit some of the local eateries available within the airport.

*Price based on the lowest price found within past 24 hours and based upon one night stay for two adults over the next thirty days. Prices and availability subject to change. Additional terms may apply.
