Similar to other major airports of the US and the world, TSA conducts most of the security screening procedures in William P. Hobby Airport.

Hobby airport is one of the first to include Advanced Imaging Technology (AIT).

When arriving at the security checkpoint, travelers will be asked by TSA staff to enter the AIT unit with the feet slightly spread apart arms raised over the head. While in this defined position, a scan of the image allows security staff to detect threats better, such as explosives, weapons, or any other dangerous objects, concealed under the clothing.

Usually, when passengers undergo a screening procedure, they will have a possibility to decline AIT screening and instead choose a physical check. Still, some travelers will be obliged to go through AIT screening if their boarding ticket shows that they have been picked for enhanced screening, under TSA regulations, before their arrival at the security checkpoint. This will occurs in a minimal number of events.

TSA also introduced a new security screening method that is more precise. TSA agents may perform the enhanced pat-down on a random basis or when a passenger asks to be pat-down rather than being in a full-body scanner or the AIT.

If a TSA agent says that an enhanced pat-down is needed, they will work with their hands, rather than with the metal-detecting tool to inspect the traveler from head to toe. TSA agents must explain the procedure that they will perform with all the steps. Passengers have the right to ask for a private screening.
