How do I reach the SeaTac Rental Car Facility via Link Light Rail using Tukwila Station, and how does the walk compare to using the terminal shuttle connection?

The SeaTac Rental Car Facility (3150 S 160th St, SeaTac, WA 98188) is accessible via Link Light Rail, but the optimal route depends on your luggage and weather. If you alight at Tukwila International Boulevard Station (the stop immediately before SeaTac/Airport Station), you can walk directly to the facility via a paved pedestrian path along International Boulevard. The distance is approximately 0. 97 km), taking 10–12 minutes at a normal pace. This route avoids the need to enter the airport terminal and wait for a shuttle. However, the path is exposed to the elements and crosses several driveways; it is best suited for travelers with carry-on luggage only. Alternatively, if you continue one more stop to SeaTac/Airport Station (the terminal station), you can take the free Rental Car Facility Shuttle from the designated pickup area on the third floor of the parking garage. The shuttle operates every 5–10 minutes during peak hours (4:00 AM–1:00 AM daily) and the ride takes 3–5 minutes. This option is climate-controlled and ideal for families, heavy suitcases, or rainy conditions. Note that the shuttle may occasionally experience delays of up to 15 minutes during high-traffic periods. For time-sensitive travelers with minimal luggage, the walk from Tukwila Station is often faster by 5–8 minutes compared to the shuttle route. Both options are free and operate 24/7, though the shuttle frequency drops to every 15 minutes between 1:00 AM and 4:00 AM.
