Getting To & From Seattle–Tacoma International Airport
The Link light rail (1 Line) provides fast, traffic-free transit between downtown Seattle and the airport in roughly 38 minutes. The SeaTac/Airport Station connects directly to the 4th floor of the airport parking garage via a covered skybridge. Taxis, app-based rideshares (Uber/Lyft), and regional buses also service the ground transportation zones on the lower arrivals drive.

Terminals & Getting Around
Terminals
Seattle-Tacoma International Airport operates out of a single main terminal building paired with four linear concourses (A, B, C, D) and two detached satellites (North Satellite and South Satellite). Concourses A through D are accessible on foot from the Central Terminal. The North and South Satellites are linked via the automated underground train system (SEA Underground), with inter-terminal transfers typically taking under 10 minutes once onboard.
Hours of Operation
The terminal facilities remain accessible 24 hours a day, though federal noise rules mean flight operations continue overnight without a formal curfew. Airside dining options and retail outlets largely close overnight.
Know Before You Go
Practical Tips
- Arrive at least 2 hours before domestic departures and 3 hours before international flights to account for heavy passenger volumes and security queues.
- Utilize the complimentary SEA Spot Saver program to reserve a specific time slot for TSA screening and bypass standard queue lines.
- Check wait times across multiple checkpoints via airport digital boards or mobile updates, as lines vary significantly by location.
- If connecting from an international flight, factor in time to clear U.S. Customs and Border Protection at the International Arrivals Facility before re-checking bags.
