An estimated 3.5 million travelers will pass through the Los Angeles International Airport this holiday season, according to Los Angeles World Airports, and if you're one of them, getting the lowdown from TSA can save you time and stress.

“We are always on the highest state of alert,” Nico Melendez, TSA spokesman, said. “We always have to find that one anomaly, that one bad guy trying to introduce something into the aviation system, and that’s every day of the year, no matter what’s happening in the world."

Since TSA is always on high alert, there are a few extra things to consider so your holiday isn't slowed down by security: 

Melendez said that preparing is key, and the best way to do that is by visiting TSA.gov to read up on all of the post-9/11 security measures. 

“Lack of knowledge is not a reason for not being prepared, because there’s a lot of knowledge out there; a lot of information out there that we’ve made available, and we’re always ready to answer your questions,” Melendez said. 

TSA's website, along with its MyTSA smartphone app and its Twitter, have outlets to find answers to various travel questions, including whether other items are OK to stow in carry-on or checked bags.
