Security Screening

TSA uses millimeter wave advanced imaging technology and walk-through metal detectors to screen passengers. Millimeter wave advanced imaging technology safely screens passengers without physical contact for metallic and non-metallic threats, including weapons and explosives, which may be concealed under clothing. Generally, passengers undergoing screening will have the opportunity to decline AIT screening in favor of physical screening. However, some passengers will be required to undergo AIT screening if their boarding pass indicates that they have been selected for enhanced screening, in accordance with TSA regulations, prior to their arrival at the security checkpoint. This will occur in a very limited number of circumstances. The vast majority of passengers will not be affected. See the responses to frequently asked questions.

Safety: Advanced imaging technology is safe and meets national health and safety standards. This technology uses non-ionizing radio-frequency energy in the millimeter spectrum with no known adverse health effects. It does not use X-ray technology.

Privacy: TSA has strict privacy standards when using advanced imaging technology to protect your privacy. Advanced imaging technology uses automated target recognition software that eliminates passenger-specific images and instead auto-detects potential threats by indicating their location on a generic outline of a person. The generic outline is identical for all passengers.

Light Outer Garment / Bulky Clothing: Any individual wearing a light outer garment or bulky clothing when screened through Advanced Imaging Technology (AIT) will be asked to divest their light outwear or bulky clothing. A light outer garment is defined as an outer layer of clothing which has a full front zipper or buttons used to fasten the outer garment, excluding button shirts. Examples include, but are not limited to, windbreakers and vests, suit/sport coats, blazers, and light jackets. Bulky clothing is a garment that is very loose or doesn't conform to the contour of the person. Examples include but are not limited to, oversize pullover hoodies, large sweaters, cardigans, and ponchos. If an individual cannot or is not willing to remove a light outer garment or bulky clothing, let the officer know and additional screening may occur.
