Don't.
King Street Station in Seattle has bag storage (assuming you're arriving there) and you'd have gobs of time to explore the city - Pike Place Market, waterfront/ferries, Space Needle, whatever. Then the Link Light rail, which leaves from a station next door to King Street, will get you to the airport in 30 min, and runs until 1 AM or so. The Tukwila station is in the middle of nowhere, with no facilities. You'd need to take a cab to the airport.

I would be getting off at Tukwilla. We also have multiple stops like Pittsburgh, Chicago, and Portland. Also if the trains happen to run late and i happen to miss the flight would the airline re book on another flight. I don't know how this would work out.
