Info iconSea-Tac Airport is the fastest growing large airport in the U.S. Sea-Tac has added staff and made several other changes to speed up TSA lines. Here are some tips to make your trip a smooth one beginning the moment you step out of your front door to your arrival at your gate.

  • Arrive Early! Arrive a minimum of two hours before domestic and three hours for international flights.
  • TSA security checkpoint lines may be longer during peak hours.
  • Peak times through TSA checkpoints typically are between 5 - 11 a.m., while increased flights during the evening create another busy period between 7 - 9 p.m.
  • Thursdays and Fridays are the busiest days of the week while Tuesday and Wednesday are the least traveled.



Traffic Advisory
From 8PM - 11PM nightly, avoid traffic congestion and consider using the airport's Departures Drive for arriving passenger pick-up.
