Children age 12 and younger may use the TSA PreCheck® lane when traveling with a parent or guardian who has the indicator on their boarding pass.
Children between the ages of 13 and 17 who will be traveling on the same reservation as an enrolled parent or guardian may also access the TSA PreCheck® lanes, provided the children have the TSA PreCheck® indicator on their boarding pass. Children 13 to 17 may be randomly excluded from receiving TSA PreCheck® on their boarding pass. In these cases, they must go through standard security screening. Children 17 and under who will be traveling alone or without a TSA PreCheck®-eligible parent or guardian must apply for TSA PreCheck® to have access to expedited screening.
