Children 17 and under can use PreCheck with a PreCheck adult when what appears?

PreCheck on the child's boarding pass.

  1. A kid's passport
  2. PreCheck on the child's boarding pass ✔
  3. A note from school

Why: Kids 17 and under may join a parent's PreCheck lane if PreCheck shows on their boarding pass. That is not guaranteed on every trip.

Huh, didn't know that: TSA uses unpredictable security measures, so PreCheck screening is never guaranteed.

My kid loves the PreCheck line. It's the only line with no snack requests.
