The Transportation Security Administration will soon allow more items to be carried onto planes including bats, corkscrews and even some knives.
From lighters, to liquids and a long list of other items, many flyers have gotten used to packing their bags without prohibited items.
That will change on April 25, when small pocket knives will no longer be taken away from travelers.
Some sports equipment, including hockey sticks and billiard cues will also be allowed in carry-on bags.
After confiscating any potential weapon for years, TSA is making the change so screeners can focus their efforts on finding higher threat items such as explosives.
Knives on planes was an explosive issue for some travelers at the Honolulu International Airport Tuesday night. After hearing of the changes, passengers worried about the safety of future flights.
"The knives are scary. It's very much dangerous and a concern to me," said former Hawaii resident Ann Kwak.
"We know in the past something as simple as a box knife has caused major problems. I don't think allowing small knives or corkscrews is safe for passengers," added Oahu resident Cynthia Reed.
Under the TSA regulations, only knives with blades less than 2.36 inches long and 0.5 inch wide would be allowed, among other restrictions.
