With TSA PreCheck™, you can breeze through airport security. Best part, children 12 and under can accompany a parent or guardian who has TSA PreCheck™ on their boarding pass. Travelers 13 and older who do not have a TSA PreCheck™ boarding pass must go through standard security lanes or apply for TSA PreCheck™.

The rules for TSA PreCheck depend on the age of your children and the status of your wife. Children aged 12 and under can always accompany a parent or guardian who has TSA PreCheck through the dedicated lanes without needing their own membership. For children aged 13 to 17, they may also go through the PreCheck lane with you only if the "TSA PreCheck" indicator appears on their own boarding pass, which usually happens if they are on the same airline reservation as the enrolled adult. However, your wife must have her own TSA PreCheck membership (KKT) to use the lane. Unlike children, adults do not "inherit" the PreCheck status from a spouse or travel companion. If her boarding pass does not have the PreCheck logo, she will be directed to the standard security line, even if you are traveling on the same confirmation number. Many travel credit cards offer a statement credit for the $78 application fee, so it is often worth getting a separate membership for her to ensure the whole family stays together during the security process.
