The TSA will soon be testing new bag screening technology at security checkpoints at several airports, including Philadelphia International.
The so-called CT scanners can more easily spot explosives and weapons hidden in carry-on bags.
They also speed up the screening process.
Passengers will be allowed to keep liquids and laptops in their carry-on bags at the checkpoints with the CT technology.
