1) Know Before You Go
Over 30 airlines serve the Seattle airport, flights traveling nonstop to over 100 destinations. The Main Terminal leads directly back to the Central Terminal, where one can find restaurants and stores after passing through security.
The airport is easy to get to from I-5 via Highway 518 and 509. The approaches to the arrivals and departures, short- and long-term parking areas are well-labeled, so driving in by car is also easy, as long as the pick-up area is not too crowded.
3) Where to Eat and Drink
You will not lack opportunities to buy a great meal or a delicious snack at SeaTac Airport. Many of the sit-down restaurants and fast-food counters are local businesses featuring local foods, and prices are consistent with what you'll find outside the airport.
4) Where to Shop
For magazines and snacks, one will find Hudson News shops throughout the airport, both pre-and post-security. Several specialty shops are located in the central terminal, including ExOfficio, Fireworks, and Made in Washington.
5) How to Spend Your Layover
There is plenty to keep you entertained, from the original art scattered throughout the terminal to the spa treatments available at the Massage Bar. For an overnight layover, peruse some nearby airport hotels like the Hilton Seattle, Red Roof Inn, or Red Lion Hotel, all of which offer a free airport shuttle service
