The full guide

Your ride into the city can begin right at the airport, aboard a train heading north through the Rainier Valley toward Downtown Seattle and beyond. Catching Seattle light rail from SeaTac is simple: the 1 Line stops at SeaTac/Airport station, and you can pay with an ORCA card, a paper ticket from a station machine or a mobile app. Keep proof of payment handy, since fare inspectors check riders at random.

Riding from SeaTac to Downtown Seattle

Think of the 1 Line as the backbone of Sound Transit's Link light rail system, a 41-mile route with 27 stations reaching from Lynnwood City Center in the north to Federal Way Downtown in the south. The airport sits along the southern half of that route, so any northbound train carries you straight toward the city.

Settle in as the train rolls through the Rainier Valley before arriving in Downtown Seattle. Westlake, in the Downtown Seattle Transit Tunnel, was one of the original end points when the line opened in 2009, and the airport station joined in December of that same year, so the rail link to the terminal is well established.

You will be riding a busy, proven service. In 2025 the line carried more than 35.5 million passengers, averaging close to 103,000 riders on a typical weekday.

Paying Your Fare

For anyone watching their budget, the key point is that light rail lets you skip pricier ways into town and pay a standard transit fare instead. Fares no longer depend on how far you travel, since distance-based pricing ended in August 2024. Check Sound Transit for the current fare before you ride, because amounts can change.

ORCA card, paper ticket or app

Pick from three ways to pay. The regional ORCA card works across the system and suits anyone planning more than one ride, while paper tickets come from the vending machines found at every station. Prefer your phone? A mobile app is the third option and works well if you like to buy on the go.

Proof of payment and fare checks

You will not find turnstiles to push through. Sound Transit relies on a proof of payment system instead, with fare ambassadors and transit police carrying out random inspections on board. Buy or tap before you ride, and keep your card, ticket or app screen ready until you step off.

When Trains Run

Trains run about 20 hours a day on weekdays and Saturdays, with a shorter day of roughly 18 hours on Sundays and holidays. At peak times, a train can arrive as often as every six minutes. Landing very early or very late? Confirm first and last train times with Sound Transit before you count on the train.

Room for Bags, Bikes and Wheelchairs

Most trains run with three or four cars, and each car holds 194 people, with 74 seats plus space for wheelchairs and bicycles. That capacity helps when you are rolling luggage aboard, though peak hours can still feel crowded.

Going Beyond Downtown

Stay on board past downtown and the same train continues north to the University District, Shoreline, Mountlake Terrace and Lynnwood. Ride south instead to reach Kent, Des Moines and Federal Way. Every station offers bus connections and bike parking, and several have park and ride lots, which helps if you are meeting someone who drives.

Getting Outside Once You Arrive

After a long flight, a walk among trees can be the best reset. Head to Discovery Park in Magnolia, where 534 acres of forest and bluffs open onto Puget Sound views. For a gentler stroll, follow the mostly level loop at the Washington Park Arboretum past the wetlands of Union Bay.

Bird watchers often make for the interior trail at Seward Park on Lake Washington. In northwest Seattle, Carkeek Park traces Pipers Creek through dense woods toward views of the Sound.
