Travel tips
Best arrival time
2 hours early usually works, but early Alaska and Delta banks need a little more margin.
Peak hours
5:00 AM to 9:00 AM and 4:00 PM to 7:30 PM.
Pro tips
- Checkpoint lines can diverge sharply, so the SEA Spot Saver mindset carries over even when you do not reserve.
- The train between the main terminal and satellites is quick, but post-security walks can still be long.
- Arrivals drive-up traffic on the lower roadway can back up around evening banks.
