As the country’s eighth busiest airport and a gateway to the Pacific Northwest, Seattle-Tacoma International Airport (or Sea-Tac) services 33 airlines and over one hundred domestic and international destinations.
So if your next trip includes a long layover here, the good news is that Sea-Tac offers plenty of amenities to keep you occupied and entertained.
The airport recently completed significant improvements to one of its main concourses and added a new International Arrivals facility.
It now boasts modern amenities and technology that save passengers time and offer them more ways to spend their layovers at Sea-Tac.
The project is part of a larger, multi-billion-dollar investment to improve traveler experience by cutting wait times, expanding lounges, and adding more retail and dining options.
To help you make the most of your layover at Sea-Tac Airport, we've broken down the essentials and the best things to do here. But first, let’s get familiarized with how big Sea-Tac really is.
How Big Is Sea-Tac Airport?
Knowing how large the airport is will help you decide how much time out of your layover you can spend shopping, dining, or sightseeing.
Even though Sea-Tac is the busiest airport in the Pacific Northwest, it is relatively small, about 2,500 acres (San Francisco’s airport is almost double that size, for example).
While that’s good news for some (you don’t need as much time to commute between gates in the airport), it is bad news for others—long security lines have become standard due to the number of passengers and the lack of TSA agents and kiosks.
The airport has a main terminal with six concourses split between two wings—the north main terminal (concourses A, B, and South Satellite) and the south main terminal (concourses C, D, and North Satellite).
A train system connects all the concourses as well as the south and north terminals, so it should not take you more than five minutes to get from the north to the south terminal and a couple of minutes between the concourses.
Also, good news: most airlines operate their flights out of the same concourse, so if the same carrier operates your arrival and departure flights, you shouldn’t have to commute far to get to your gate during your layover. Here’s a handy airline location guide.
Explore Sea-Tac’s Airport Lounges
Airport lounges provide a quiet place to relax and unwind from the busy waiting and dining areas. And Sea-Tac has several that you can choose from.
Because of the pandemic and to limit the number of passengers in lounges, many airlines made lounges available only to travelers with certain types of credit cards or tickets. Here’s what you need to know:
- The Club SEA: This stylish lounge has locations at Concourse A (open daily 5 am – 12 am) and S (open daily 6 am – 7 pm), where anyone can purchase a day pass for $50. Both offer plenty of seating, complimentary food and beverages, WiFi, and TVs.
- Alaska Lounge: Alaska Airlines recently renovated both of its lounges at Sea-Tac (concourses C and D), and the airline pulled all the stops. Floor-to-ceiling views, gourmet coffee, large buffet stations, local brews, free WiFi, and chic design await Alaska Airlines members here. While purchasing a day pass is not an option here, there are other ways to get access to the lounges.
- American Express Centurion Lounge: This brand new lounge in the main terminal (open daily 5 am - 10 pm) has plenty of premium amenities to make your stay more comfortable—healthy snacks, chef-prepared food with a focus on local ingredients and flavors, a long selection of drinks, including cocktails dreamed up by one of the country’s most prominent mixologists, Jim Meehan. Plush seating, free WiFi, power outlets, and a bar with stunning views round out this lounge’s draws. No day passes are available, but you can still get in if you have certain types of American Express cards.
- United Club: Free WiFi, snacks, and a bar are offered in United’s lounge, located in Concourse A (open daily 4:15 am—10:00 pm). One-time day passes are sold for $59.
- Delta Air Lines Delta Sky Club: Take advantage of this spacious, sunlit lounge with beautiful views, comfortable seating, communal-style tables perfect for working, and power outlets if you are a Delta Sky Club member or frequent Delta Traveler (learn more ways to access the lounge here). The lounge is located in Concourse A and is open daily from 4:15 am to 12:00 am.
- USO Center: Military members and their families can access the lounge, which offers many family-friendly amenities, including a play area with games, workstations, sleeping areas, luggage storage, a movie theater, and snacks and drinks. The lounge is located in the main terminal and is open Mon, Wed, and Sat (8 am—4 am the next day) and Tues and Thur (8 am—12 am); it is closed on Fridays and Sundays, and unfortunately, it is not available to veterans.
Catch Up on Work in Sea-Tac
Need a quiet place to make a business phone call or to get some work done? You can reserve an “escape pod,” plush private cabins equipped with a table, LED lighting, WiFi, a 24-inch screen, and seating, perfect for reading, making calls, or maybe even taking a nap (just note that you can’t recline or lie down).
There are 11 Escape Pods available for booking throughout Sea-Tac Airport (exact locations here) in 15-minute intervals for up to 2 hours. Since there are few of them, we recommend you book yours well in advance.
The Best Places to Eat in Sea-Tac
Sea-Tac now has even more retail and dining options. Here are our favorite eateries out of over 45 restaurants:
- Salty’s at the SEA and BrewTop Social: This two-level dining spot offers authentic Pacific Northwestern flavors (seafood lovers, rejoice) by the iconic Seattle restaurant, as well as many local beers. The raw bar with poke, oysters, and prawns is best enjoyed with a glass of white wine. Or, if you prefer something more substantial, choose from an extensive menu featuring breakfast, lunch, and dinner options. Open daily 6 am-10 pm.
- Lucky Louie Fish Shack: This is another eatery focused on offering fresh, sustainable seafood (creamy clam chowder, shrimp salad, honey salmon teriyaki), as well as their famous fish-shaped creamy cheesecake waffles with sauces. Open daily from 5:30 am—10 pm (and 8 pm on Tue, Wed, and Sat)
- Beecher’s Handmade Cheese: Get your Beecher’s cheese fix at this walk-in spot, including a variety of grilled cheese sandwiches and melts, mac&cheese, as well as soups and salads. Open daily from 6 am—8 pm.
- Africa Lounge: It’s arguably one of the most popular restaurants in Sea-Tack. This eatery serves Congolese fare, such as spicy beef sambusas, African-inspired cocktails, and décor that couldn’t be more on theme. Open daily from 6 am to 9 pm.
- Floret: Vegetarians will love Floret’s meat-free options, including black bean and corn quesadilla, avocado toast, black bean burger, grain bowls, and citrus and snap pea panzanella. A selection of local coffees and kombuchas is also available. Open from 4:30 am to 8 pm.

Listen to Live Music and Explore the Airport’s Art Collection
Sea-Tac has an impressive cultural program that immerses travelers in local art and music, making their layovers more pleasant.
The airport’s concert series, which was canceled during COVID-19, is now back. Live performances by four artists are held daily from 9:00 am to 2:30 pm at multiple locations throughout the airport. Check out the latest schedule here.
A self-guided art walk is also available through the airport’s app for those looking to stretch their legs and peruse the airport’s top-notch public art collection, featuring glass, sculpture, mixed media, and photography by local and international artists.
Where Can I Store My Bag in SeaTac?
Smarte Carte’s Baggage Storage operates a storage facility on the arrivals level of Baggage Claim 9.
You can drop off your luggage and larger items such as strollers, wheelchairs, bicycles, and frozen or refrigerated items (nursing mom, take notice), so you don’t have to lug them around.
Rates are available here.
Traveling with Children?
Sea-Tac airport also includes nursing rooms and suites, which offer a quiet, private place with adjustable lighting, rocking chairs, power outlets, and more.
Nursing rooms are in Concourse A inside the children’s play area and Concourse D on the lower level near Gate D24. Learn more about Sea-Tac’s nursing rooms here.
Things to Explore Outside Sea-Tac
If your layover falls during rush hour, consider areas outside downtown, where traffic can slow you down significantly.
West Seattle, for example, is an excellent option with its boardwalk, stunning waterfront views, and sandy Alki Beach. The 1913 lighthouse is also available for tours in the spring and summer.
Hit The Junction is a lively commercial area packed with stores, coffee shops, and restaurants. And if you’d like some quiet (and get some steps in), head to Lincoln Park, Seahurst Park, or Angle Lake Park (a short 5-minute drive from the airport).
Another great option if you’re short on time is Highline SeaTac Botanical Garden, a serene 11-acre park with two spectacular gardens, including a Japanese one bursting with colorful blooms.
Lastly, if you have your mind set on visiting places like Pike Place Market or the Space Needle, your best and safest bet is a private Seattle town car service with a chauffeur to pick you up and drop you off at the airport.
Things to Keep in Mind When Leaving the Airport
As we mentioned, Sea-Tac is smaller than other airports that service a similar number of passengers, which unfortunately results in notoriously long wait lines.
So before you decide to leave the airport, make sure your layover is long enough and give yourself plenty of time for security and luggage check-in — ideally, at least six hours on a typical day.
During busy travel seasons, holidays, or weekends, unless you travel with only a carry-on and have expedited check-in, such as TSA Pre-Check, you will need much more time since security lines sometimes extend outside the airport.
Sea-Tack has five checkpoints:
- The main terminal checkpoint is open 24 hours for general screening and limited hours for CLEAR (6 am - 4 pm) and TSA Pre-Check (10 pm to 4 am).
- Checkpoints 1 and 2, most convenient for gates A and S, are open from 4 am until 1 pm for checkpoint 1, and 11 pm for checkpoint 2.
- Checkpoint 4, convenient for gates C and D, is open from 4 am to 10 pm.
- Checkpoint 5 is operational from 4 am to 8 pm for gates D and N.
Travelers at Sea-Tac can take advantage of expedited screening programs (TSA Pre and Clear, which are membership-based) and SEA Spot Saver, which enables them to schedule a screening appointment in advance via the airport’s app.
Transportation Options to Downtown Seattle from Sea-Tac
While there are many ground transportation options from Sea-Tac to Seattle and Bellevue, the best way to ensure you return to the airport on time is to hire a car service with a professional driver who knows the city’s traffic patterns very well.
Public transportation can be unreliable and slow (the Light rail trip to Pike Place, for example, could take about 40 minutes). At the same time, taxis or ride-share apps have one significant disadvantage—you never know who the driver is and how well they know the region.
