TSA raising aviation security baseline with stronger domestic security measures
>WASHINGTON – To ensure the security of airline passengers and the nation’s airports, the Transportation Security Administration (TSA) is implementing new, stronger screening procedures for carry-on items that require travelers to place all electronics larger than a cell phone in bins for X-ray screening in standard lanes.
>As new procedures are phased in, TSA officers will begin to ask travelers to remove electronics larger than a cell phone from their carry-on bags and place them in a bin with nothing on top or below, similar to how laptops have been screened for years. This simple step helps TSA officers obtain a clearer X-ray image.
