It's been more than a decade since hi-jacked planes crashed into the World Trade Center and the Pentagon. It was an event that changed airport security forever. But now some of those rules are being relaxed.
Box cutters were used to take over those planes and while they are and will still be illegal, small knives will soon be allowed on planes.
It's a change that has many people worried.
"I think it's ridiculous," passenger Janae Tostenson said.
When you think of going through airport security, you probably don't think brining a knife is a good idea. But on April 25, knives with blades shorter than 2.36 inches and no wider than half an inch will be allowed.
"I actually didn't believe it. A co-worker was reading the news and blurted it out and I was like you're kidding. So, I was very shocked to hear it," Tostenson said.
Tostenson and her husband are traveling with two young children. She says she would much rather see some of the liquid amount guidelines relaxed rather this one.
"Especially if you've got picky kids that like certain juices or if you've got kids with allergies or things like that and if the planes don't have that on there, then you're kind of stuck," Tostenson said.
The knives can't have locking or fixed blades and can't be made from a molded handle. It's a change that brings one thing to Ashley Dwyer's mind.
"Safety and being precautions of those measures, really just thinking why they had it in place in the first place and now they're reversing that rule. I guess the main thing would be what would happen if you were on a plane and someone would use that in a bad way?" Dwyer said.
While she's not excited about the changes, Dwyer does hope there is a positive outcome.
“I hope it’s just to increase people getting through the lines, getting on the planes and ensuring that it’s fast moving. It’s a fast moving world. We just want to get going, no one wants to stand around and wait so hopefully it does help that. But the safety concerns me a little bit,” Dwyer said.
Many groups, including flight attendants and air marshals, have asked the TSA to reconsider the changes.
Some lawmakers have also taken a stand against the new knife policy.
