Anna emailed us with a link to the Port of Seattle website, which says that Sea-Tac’s parking garage is currently full, and all nearby parking lots are also full.
The Airport Parking Garage is currently full. Parking is also full in off-airport lots; even parkers with reservations are being turned away. If you have a reservation, call ahead to your lot. Travelers should use alternate transportation to get to Sea-Tac Airport.
So, call a cab or ask a friend to drive you. And keep checking that link to see if the lots open up.
