It is considered to be one of the least expensive mode of transportation which runs between the different hotels of Seattle and the SeaTac airport. You can purchase the tickets for the Airporter from the select downtown Seattle hotel concierge or Downtown Airporter drivers. You will be also able to get the tickets from the Gray Line of Seattle desk located at the south end of the Seattle-Tacoma International Airport main terminal.
