Here are a few practical tips to help you get through security faster: 1. Arrive Early
For domestic flights, arrive at least 2 hours before departure; for international flights, give yourself at least 3 hours. 2. Use TSA PreCheck

Whenever possible, book flights that depart during off-peak hours, such as mid-morning or early afternoon on weekdays. 4. Pack Smart
Make sure your carry-on complies with TSA rules. Have liquids under 3.4 oz in a clear bag and remove electronics if you're not in a PreCheck lane. Terminal Differences at Seatac
Seatac has multiple checkpoints—some terminals experience more congestion than others. Knowing which security checkpoints are closest to your gate and which are less crowded can help you choose wisely. Airport staff or posted signs usually provide this guidance once you arrive. Final Thoughts
Staying informed about Seatac security wait times is one of the best things you can do to ensure a smoother travel experience.
