Once you factor in additional expenses such as the airport concession fee recovery, local taxes, and the cost of gas (approximately $5. 00 per gallon), the baseline cost easily exceeds $70 daily. Furthermore, if you plan to park at or near Tukwila International Boulevard Station, daily parking fees can add another $5 to $15.

For solo travelers or couples not carrying excessive cargo, the Link Light Rail is unequivocally the most economical and efficient choice, saving over $60 per day compared to a rental car.
