TSA Requirements. The TSA requires that adult passengers ages 18 and older show valid photo ID at the security checkpoint. Children, however, are not required to present such identification. This does not mean, however, that children will be able to fly without it.
ID Requirements & Piercing Age Restrictions. You must be at least 18 years old (or 16 years old, with a parent or guardian present) for any service from our piercers. We need your ID every time you request any procedure, even if you have shown it on a prior occasion.
