A $3 direct bus makes transportation from SeaTac to Tacoma much cheaper than many airport transfers. Sound Transit Route 574 runs from Seattle-Tacoma International Airport to Tacoma Dome Station without a transfer, and scheduled trips usually take about 31–36 minutes.

Route 574 is the practical default for solo travelers staying near downtown Tacoma. A rideshare, taxi, or reserved shuttle earns its higher price when luggage is heavy, several people can split the fare, or the final address sits far from Tacoma Dome Station.

What Is The Cheapest Way From SeaTac To Tacoma?

Sound Transit Route 574 is the cheapest straightforward option from SEA Airport to Tacoma. The adult fare is $3, eligible reduced fares are $1, and riders age 18 or younger travel free.

The southbound bus stops at SeaTac Airport Terminal Bay 2, Federal Way Downtown Station, and Tacoma Dome Station before continuing toward Lakewood. Current scheduled airport-to-Tacoma Dome running times range from roughly 31 minutes early in the day to about 36 minutes around midday, but freeway traffic can add time.

Service covers early arrivals and late flights better than many visitors expect. Current terminal departures begin around 4:40 a.m. and continue until about 12:40 a.m., with buses commonly spaced 30 or 60 minutes apart depending on the hour.

How To Catch Route 574 At The Airport

Route 574 picks up at the south end of SEA Airport’s main terminal on the lower drive, at SeaTac Airport Terminal Bay 2. The stop is on the terminal roadway, not at the Link light rail platform across the parking garage.

1. Collect checked bags and follow signs toward ground transportation and the lower drive.
2. Walk toward the south end of the main terminal and locate Bay 2.
3. Confirm that the bus display shows Route 574 toward Lakewood.
4. Pay while boarding with an ORCA card, contactless bank card, Transit GO Ticket, or exact cash.
5. Exit at Tacoma Dome Station, normally Zone H on southbound trips.

Allow extra walking time from baggage claim to Bay 2, especially after an international arrival or a gate at the north end.

Sound Transit posts live arrivals, service alerts, fares, and the full timetable on the official Route 574 schedule. Check it after landing because traffic, holidays, and temporary stop changes can alter the trip.

SeaTac To Tacoma Transportation: Every Route Compared

Route 574 wins on price, while a rideshare or private vehicle wins when the destination is not close to Tacoma Dome. The right choice depends more on the final Tacoma address and party size than on the airport pickup itself.

Road times swing with Interstate 5 traffic, airport congestion, and the exact Tacoma neighborhood. North Tacoma, Point Defiance, and University Place add distance beyond downtown, so a door-to-door estimate should use the actual address rather than “Tacoma” alone.

When A Car Or Shuttle Makes More Sense

A car-based transfer makes more sense for three or four travelers, late-night arrivals with a long wait for the next bus, or Tacoma addresses that require another ride from Tacoma Dome. Splitting a $60–$90 ride can narrow the per-person gap enough to justify door-to-door service.

App-based rideshare pickup is in the third-floor Ground Transportation Plaza, in marked stalls 1–34. SEA Airport warns that evening pickup traffic is often heaviest from 8 p.m. to midnight, so the driver may need extra time to reach the garage.

Metered taxis also wait on the third floor of the parking garage, on the north and south curbs. A reserved door-to-door shuttle can be useful for passengers who want luggage help or a confirmed vehicle, but shared service may take longer if other riders are dropped off first.

Rental cars fit travelers continuing beyond Tacoma or visiting places poorly served by local transit. Every airport rental company operates from SEA Airport’s off-site facility; free shuttles run 24 hours a day, and the ride from the terminal takes about five minutes before counter and vehicle pickup time.

Stay Near The Right Tacoma Stop

Downtown Tacoma and the Dome District are the easiest bases for travelers using Route 574. North End and waterfront stays offer different surroundings, but they add a local bus, T Line connection, or rideshare after the airport bus.

Use the map to compare Tacoma hotels against Tacoma Dome Station and the places you plan to visit:

Where Will You Arrive In Tacoma?

Route 574 arrives at Tacoma Dome Station, a regional transit center east of downtown Tacoma. Tacoma Dome is convenient for the Dome District and onward transit, but it is not the front door of most downtown, waterfront, or North End hotels.

From Tacoma Dome Station, travelers can connect to the T Line, Pierce Transit buses, or a short rideshare. A downtown hotel may be reachable by local transit, while Point Ruston, Proctor, Point Defiance, and many residential addresses usually need a longer local connection.

Travelers arriving after a long flight should compare the total trip, not just the airport leg. A $3 bus plus a local rideshare can still cost far less than an airport rideshare, but waiting for two separate vehicles may not suit a late arrival or a family carrying several bags.

Pick The Right Route For Your Trip

Route 574 is the right pick for most solo travelers and anyone focused on cost. A rideshare or taxi is the stronger choice for direct delivery, while a reserved shuttle suits passengers who value a confirmed pickup and luggage help.

• Lowest cost: Take Route 574 to Tacoma Dome for $3.
• Fastest door to door: Check Uber, Lyft, or a taxi using the full Tacoma address.
• Families and small groups: Compare the total rideshare fare against separate bus fares and the last-mile connection.
• Heavy luggage or mobility needs: Reserve a door-to-door vehicle and confirm accessibility before arrival.
• Trips beyond Tacoma: Rent a car only when the wider itinerary needs one, since downtown parking adds cost.

The clearest overall verdict is Route 574 for budget, rideshare for direct access, and a reserved private vehicle when schedule certainty matters more than price.
