Getting to Seatac Airport from downtown Seattle has been easier -- and cheaper -- since the Airport light rail station opened in December. Operated by Sound Transit Link Light Rail takes you from Westlake Center in downtown Seattle to the airport in 37 minutes. There are 10 stations along the route including stops in the International District, Pioneer Square and at the Stadium.
One-way adult fares are $2.50 and youth ages 6 -18 are $2. (Keep your ticket handy to show to a Fare Inspector on board). Tickets can be purchased from vending machines at the station that work much like automated bank teller or parking ticket machines.
Passengers need only walk from the airport staion along a covered, lighted, level walkway on the mezzanine level to the terminal. At Westlake Center's transit hub connections can be made to buses. Or most hotels are within a few blocks of the station.
After arriving home from Hawaii, we took a taxi home, slightly over 20 miles from the airport and the fare with tip was $61. Next time using Light Rail and connecting to the Metro bus, the cost per person will be $4.50 or $9 for the trip.
