Cheap flights from St Louis to Seattle

The easiest way to explore everything in Seattle, including the Seattle Center, the University of Washington campus and Pioneer Square, is with a car. The Seattle-Tacoma International Airport (SEA) is the best place to find an affordable rental car. After picking one up, you might want to drive out to Mount Rainier National Park for the stunning views, some fresh air and the chance to stretch your legs. When you've shaken off the jet lag, head for the Seattle Aquarium, located right on the waterfront.

Key Facts

Although Seattle is known for its gloomy days and coffee association, there's also a thriving music scene, numerous farmers markets with organic produce, and a variety of restaurants serving authentic international cuisine.

Travelers can check out the history of the Seattle music scene at the Experience Music Project Museum. Let your imagination run wild at the Chihuly Garden and Glass Museum where massive art installations are created from blown glass.

Hints and Tips

It takes about six hours to reach Seattle from the Lambert-St. Louis International Airport (STL). SeaTac Airport offers many travels the chance to connect to other flights and has several terminals, on top of a large central area with food and shopping options.
