Travelers have been missing Alaska Airlines flights  out of Sea-Tac Airport this week because of long lines at TSA checkpoints. The delays apparently are being caused by a combination of high numbers of summer travelers and the closure of one security gate for construction. If you're planning on catching an Alaska Air flight out of Seattle anytime soon, get to the airport early. The Seattle Times is offering  further tips for making sure you get to your plane on time.
Remember that any of the TSA checkpoints at Sea-Tac will let you get to any of the departure gates. So look for the shortest line. If you’re with more than one person, divide up to check the security lines then phone each other and head to the shortest one. See the checkpoint locations here.
Some of the busiest times are 4 p.m. to 9 p.m. when a lot of Alaska flights leave (Alaska is the biggest carrier at Sea-Tac). For your peace of mind, allow even more than two hours to get through the ticket counter/baggage check/security lines at such times. If you’re really early, you can always get a snack or shop by the gates.
