To and from SEA

Avoid the hassles of driving and parking. Consider alternative modes of transportation to/from the airport like a Link Light Rail, bus, taxi, ride share options, shuttles, airporters, or door-to-door options.

A busy parking garage makes airport parking a challenge. Be aware that during busy travel periods you may need extra time to find a parking stall.

If you decide to drive and park, the new automated parking guidance system marks available and occupied stalls with green and red lights.

It's dangerous to park on the shoulder of the airport drive. Use the newly reconfigured Cell Phone Lot.

At the airport

Get here early! Depending on your needs, you may need more time. Passengers should arrive two hours before domestic travel and three hours before international travel. 

Upgrade SEA highlights more than $5 billion in improvements underway over the next five years.

Construction for safety and accessibility improvements unfortunately means temporary closures along garage skybridges.
