Seattle Flights

Ready for an adventure? Book flights to Seattle, Washington, and discover why they call it “The Emerald City.” Known for its lush forests, the heart of Seattle is conveniently located just 13 miles north of the Seattle-Tacoma International Airport (SEA).

Sea-Tac Airport strives to make your traveling experience a comfortable one. Hungry? Choose from cafes, bars, bakeries, sit-down restaurants, and fast-food stops to satisfy your taste buds. Bored? Relax at one of the massage parlors, shop for souvenirs, or pick up some snacks and magazines for your next flight. The airport even hosts live musicians, who play throughout the terminals. From bookstores to nail salons, you’ll find plenty to keep you entertained at this airport.

Airport Transportation

If you’re booking airfare to Seattle, don’t forget to arrange for transportation to and from the airport. Fortunately when you’ve traveling through Sea-Tac Airport, you have a number of options to consider.

For starters, you can always book one of our Seattle car rentals right here to have a vehicle waiting for you as soon as your flight lands. With your own set of car keys, you have the freedom to explore “Jet City” without worrying about timetables or cab fares. Another option is to take advantage of the airport’s ground transportation options.

The airport includes a Link Light Rail station, which connects the terminal to downtown Seattle. The King County Metro Transit and Sound Transit buses service the airport as well. If you’re still looking for other transportation options, flag down a taxi or schedule a shuttle to transport you to your final destination.

Seattle Activities

While you’re browsing Seattle flights, start imagining all the fun you’ll have once you let loosen vacation. If you’ve never experienced the Space Needle, place this attraction at the top of your itinerary. Ascend 520 feet to arrive at the observation deck, which features 360-degree views of the cityscape, from Mount Rainer to the Smith Tower. Next, head to the legendary Pike Place Market. One of the country’s oldest markets, Pike Place boasts nine acres of vendors serving fresh fish, produce, pastries, and more. Buskers serenade on the corners, while the smell of baked goods wafts through the alleys. Before resting up at one of the best hotels in Seattle, don’t miss Olympic Sculpture Park, Chihuly Garden and Glass, and Waterfront Park.

The rainiest months are between October and April, though even in winter there’s always a chance for some sunshine. The colder months tend to be wetter, and sometimes the city even gets some snow. Summer usually sees the best weather, with sunny days that linger in the mid-70s F.
