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.
Age restrictions for flight applicants. Applicants must be older than 18 but not more than 32 years of age at the start of flight training (32 years of age is defined as not having reached your 33rd birthday). Requests for age waivers are considered on a case-by-case basis. USAREC will forward the completed application packet for any applicant requesting an age waiver to the Organization and Personnel Force Development Directorate. Everything included in the packet is considered.
