Insider tips and tricks 

The following insider info and tips will help expedite your next trip through Sea-Tac Airport:
  • Arrive Early! Travelers are encouraged to arrive a minimum of two hours before domestic and three hours for international flights – give yourself time to park, check-in and get through security. Additionally, if you’re checking bags, add some extra time on top of it. It’s always better to be early.
  • The busiest times at TSA checkpoints typically are between 5 -11 a.m., while increased flights during the evening create another busy period between 7 - 9 p.m. The days of sleepy evening hours is no longer the reality at Sea-Tac.
  • Peak hours may mean TSA checkpoints are longer, so please plan accordingly and arrive with plenty of lead time. 
  • Thursday and Fridays are the busiest days during the week.
  • Pack Safe: know before you travel what items are and aren’t allowed in carry-ons and checked bags.
  • Print boarding passes ahead of time or use self-serve kiosks at ticketing.
  • Travelers can reach their gates from any TSA security checkpoint. The central checkpoint is open 24/7.
  • Empty liquids before you get into TSA lines.
  • At security checkpoints, have your boarding pass and ID ready and remove laptops from their bags ahead of time.
