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 while Tuesday and Wednesday are least traveled.
  • 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.
  • Sign up for Trusted Traveler programs such as Pre-Check or Global Entry. These programs allow approved travelers to take specific designated lines for quicker service through checkpoints. Clear is another option that uses biometric technology to bypass the ID check station.
