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.
A TSA Preâ logo or âTSA PREâ is also printed on the boarding pass near the traveler's name. When the TSA agent at a participating airport scans the barcode, eligible travelers will be directed to a TSA Preâ lane. Note that not all airports offer TSA Preâ. Children ages 12 and under may accompany an eligible traveler through TSA Preâ. The TSA will always incorporate random and unpredictable security measures throughout the airport, and in order to retain a certain element of randomness, no individual will be guaranteed expedited screening.
