The Transportation Security Administration (TSA) has acknowledged that its new Analogic screening machines are causing significant delays at airport security checkpoints. These machines, which use 3D imaging technology, were intended to expedite the screening process by reducing the need for manual inspections. However, a software glitch has resulted in increased manual interventions.

The TSA initially anticipated that the new technology would enable them to eliminate the 3-1-1 liquid rules, which restrict passengers to carrying liquids in containers of no more than three ounces within a 100-milliliter bag. While similar regulations have been phased out in the U.K. and Europe due to advancements in screening technology, the glitches with Analogic machines have led to a reversal of this trend.

According to TSA officials, they aim for consistent rules across all airports and have decided not to lift the liquid ban until every checkpoint is equipped with these new machines. This nationwide rollout is projected to be completed by 2040.
