Quick Answer
For most travelers, the best way to get from Sea-Tac Airport to Seattle University is the Link Light Rail. It's the cheapest ($3.00) and most reliable option, taking about 45-50 minutes total. Ride from Sea-Tac/Airport Station to Capitol Hill Station, then walk 15 minutes or take a short bus ride north to campus. For direct door-to-door service, a taxi or ride-share takes 20-40 minutes but costs $35-$50+.
1. Link Light Rail: The Best Public Transit Option
The Link Light Rail is the top recommended transport for its unbeatable combination of low cost, reliability, and proximity to Seattle University. It bypasses Seattle's notorious traffic and drops you just a 15-minute walk from campus.
| Key Metric | Details |
|---|---|
| Total Travel Time | ~45-50 minutes (35 min train + 10-15 min walk) |
| Cost (One-Way) | $3.00 for adults (Capitol Hill Station fare) |
| Operating Hours | 5:00 AM – 1:00 AM (Daily) |
| Frequency | Every 8-15 minutes |
| Closest Station to SU | Capitol Hill Station (0.7 miles / 15-min walk south of campus) |
Step-by-Step Guide:
- Find the Station: From baggage claim, follow green “Link Light Rail” signs to the parking garage. Take elevators/escalators to the 4th floor. The covered walkway leads directly to the airport station (5-8 min walk).
- Purchase Ticket: Buy a ticket at the vending machine (cash/credit/debit) or use an ORCA card (highly recommended for transfers). Select “Capitol Hill Station” as your destination ($3.00).
- Board the Train: Take any northbound train (towards “Northgate”). The ride to Capitol Hill takes about 35 minutes with 7 intermediate stops.
- Final Leg to Campus: Exit at Capitol Hill Station.
- Walk: Walk north on Broadway E for 0.7 miles to the main campus at 901 12th Ave.
- Bus Transfer (Free with ORCA/Transfer): Catch King County Metro Bus Route 9, 49, or 60 heading north on Broadway. Ride 2-3 stops to E Jefferson St & 12th Ave E, right at campus edge.
Depth Analysis: Pros, Cons & Who It's For
Pros: Extremely cost-effective; immune to road traffic; frequent service; luggage-friendly; safe and well-lit stations; free Wi-Fi on platforms; seamless connection to city transit.
Cons: Not door-to-door; requires a walk/bus transfer; can be crowded during peak commuter hours (7-9 AM, 4-6 PM).
Best For: Solo travelers, students, budget-conscious visitors, and anyone arriving during daytime or evening hours. It's the default smart choice.
2. Bus & Shuttle Services
While the Light Rail is superior, direct bus and shuttle services offer alternative routes, especially if your final destination is on the west side of SU campus.
A. King County Metro Public Bus (Route 124 + Transfer)
A slower but functional public bus option. Take Route 124 from the airport (Stop at International Blvd & S 176th St) to downtown Seattle (4th Ave & Pike St). Transfer to a eastbound bus like the Route 12 which goes directly past Seattle University on E Jefferson St.
- Cost: $2.75 (with ORCA card, includes free transfer).
- Time: 60-80 minutes, highly variable with traffic.
- Verdict: Only use if you need a bus-specific destination. The Light Rail + short walk is almost always faster and simpler.
B. Shared Airport Shuttles (e.g., Shuttle Express)
Shared van services that drop off at specific hotels or addresses. You can book a drop-off near Seattle University.
- Cost: $25-$40 per person, depending on promotions.
- Time: 40-60 minutes (depends on other drop-offs).
- Best For: Travelers who prefer a pre-booked, managed service but find taxis too expensive. Less efficient than ride-share for groups.
4. Shared Ride Services (Uber Pool, Lyft Shared)
A hybrid option between public transit and private ride-share, offering lower costs by sharing the ride with others heading in a similar direction.
- How it Works: Request a shared ride via the app. You may be matched with 1-2 other passengers. The route may have minor detours for pickups/drop-offs.
- Cost: Typically 20-30% cheaper than a standard UberX/Lyft. Expect $25-$35 to Seattle U.
- Time: Adds 5-15 minutes to the standard ride-share time.
- Best For: Solo or duo travelers wanting door-to-door convenience at a lower price than a standard ride-share, and who are flexible on time.
- Drawback: Not ideal during a pandemic or if you have excessive luggage. Availability can be limited at off-peak times.
5. Rental Car & Driving Directions
Renting a car at Sea-Tac is straightforward, but driving and parking at Seattle University is challenging and expensive. Only recommended if you plan extensive travel outside Seattle.
Rental Process at Sea-Tac:
After collecting baggage, take the Blue Rental Car Shuttle from the center island on the 3rd floor of the parking garage. Shuttles run 24/7 to the off-site Rental Car Facility, which houses all major companies (Hertz, Avis, Enterprise, etc.).
Driving Route to Seattle University:
- From the rental facility, follow signs to I-5 North.
- Take I-5 N for about 15 miles.
- Take Exit 166 for James Street.
- Turn right onto James St, then left onto 12th Ave. The campus will be on your right.
- Total Drive Time: 25-50 minutes (highly traffic-dependent).
The Major Challenge: Parking
Seattle University has limited visitor parking that is expensive and often full. Daily rates in campus garages (like the Broadway Garage) can exceed $20-$30 per day. Street parking is metered and time-limited. Recommendation: Unless necessary, use public transit to reach campus and consider renting a car later for a weekend trip if needed.

| Shared Ride (Uber Pool) | 30-55 min | $25 - $35 | Medium-High. Cheaper ride-share with potential detours. | Cost-conscious solo travelers |
| Shared Shuttle Van | 40-60 min | $25 - $40 | Medium. Must book ahead, multiple stops. | Pre-booked, hotel drop-off |
| Public Bus (Route 124 + Transfer) | 60-80 min | $2.75 | Low. Slow, traffic-dependent, requires transfer. | Only if near specific bus line |
| Rental Car | 25-50 min | $40 - $80/day + Parking ($20-$30/day) | Low for campus. High for exploration. Parking is costly/difficult. | Those exploring outside Seattle extensively |
Our Verdict: The Link Light Rail is the undisputed best value. For ultimate convenience, especially in groups or with lots of gear, a ride-share is worth the premium.
7. Insider Tips & Traveler Experience
- Get an ORCA Card: If you'll use any public transit in Seattle, buy a reloadable ORCA card at the Light Rail station. It works on trains, buses, and ferries, and offers free transfers within 2 hours.
- Free Airport Train to Light Rail: If your baggage is heavy, use the free Airport Train (SAT) from the main terminal to the “Airport Station” stop, which is right at the Light Rail entrance.
- Rush Hour Reality: Weekdays 7-9 AM and 4-6 PM, I-5 and downtown streets are clogged. The Light Rail becomes the fastest option during these times, not just the cheapest.
- Weather Preparedness: Seattle is rainy. Have a rain jacket or small umbrella accessible for the walk from Capitol Hill Station. The walk is along busy Broadway with covered awnings part of the way.
- Campus Layout: Seattle U is an urban campus integrated into the Capitol Hill neighborhood. The main administrative address is 901 12th Ave, but buildings are spread between E Jefferson St and E Cherry St, from 12th to 14th Aves.
- Luggage Storage (If Early): If you arrive before check-in, some campus offices (like Student Activities) may hold luggage temporarily—call ahead. Alternatively, use a service like Bounce to find secure luggage storage locations in Capitol Hill.
- Student Move-In Days: If arriving for fall move-in, expect extra congestion around campus. The university often has volunteers and specific traffic patterns; check communications from SU Housing.
FAQs: Sea-Tac Airport to Seattle University
What is the cheapest way to get from Sea-Tac Airport to Seattle University?
The absolute cheapest way is to take the Link Light Rail from the airport station to Capitol Hill Station, which costs only $3.00. From there, it's a short 10-15 minute walk or a quick bus ride (using a free transfer) north to the Seattle University campus.
What is the fastest way to get from SEA Airport to Seattle University?
During daytime light traffic, a taxi, Uber, or Lyft is the fastest door-to-door option, taking 20-30 minutes. However, during rush hour (7-9 AM, 4-6 PM), the Link Light Rail is often more reliable and faster, taking about 45-50 minutes total, as it avoids road congestion.
Is there a direct train from Sea-Tac to Seattle University?
No direct train stops on campus. The Link Light Rail gets you very close. You must disembark at Capitol Hill Station (the closest stop) and then walk 0.7 miles (15 mins) north or transfer to a local bus (Routes 9, 49, 60) for one stop to campus.
How do I get to Seattle University late at night or very early in the morning?
The Link Light Rail operates from 5 AM to 1 AM daily. For flights arriving between 1 AM and 5 AM, your only options are taxi, ride-share (Uber/Lyft), or pre-booking a private shuttle. Ride-shares are readily available 24/7 at Sea-Tac.
Is the Link Light Rail easy to use with luggage?
Yes, it's very luggage-friendly. Trains have level boarding, wide aisles, and designated spaces for suitcases and bags. Elevators and escalators are available at both Sea-Tac and Capitol Hill stations. Avoid peak commuter hours for a more comfortable ride with luggage.
Where exactly do I catch the Light Rail at Sea-Tac Airport?
The airport station is connected to the main terminal via a covered walkway on the parking garage level. Follow the green and white "Link Light Rail" signs from the baggage claim area. It's about a 5-8 minute walk from any carousel. You can also take the free Airport Train to the station.
What's the best option for a group of 4 or more?
For a group of 4+, splitting a Lyft XL or Uber XL (which accommodates 6) often becomes cost-competitive with buying multiple light rail tickets, especially if you have lots of luggage. It offers direct, door-to-door service. Compare the total cost of 4x $3 light rail fares ($12) vs. a $35-$45 ride-share.
Can I use my ORCA card on the Light Rail from the airport?
Absolutely. Using an ORCA card is the most convenient way to pay. Tap your card when you enter the station at Sea-Tac and tap again when you exit at Capitol Hill. The fare is automatically deducted. Transfers to King County Metro buses within 2 hours are free.
