- Make sure that the name on your boarding pass and your government-issued ID match. This is a TSA requiremnet. So when you confirm your flight, make sure the name on your airline reservation matches whatever I.D. you plan to use (driver's license or passport, for example).
- Ask about baggage policies for your airline: How many bags are allowed; what the fees are; and what are the size and weight restrictions.
Use Web Check-in. Most airlines offer it. You can print your boarding pass at home; if you don't have luggage to check you can bypass the ticket counter completely and go straight through the security checkpoint and your gate.

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.
- Peak hours can mean TSA checkpoint lines are longer, so please plan accordingly.
- 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.
- 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. (See the tip under "At home" above.)
- 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.
