This bill directs the Federal Aviation Administration to update its safety regulations within 90 days to allow parents and caregivers to use approved lap-held child restraints for babies under age 2 during flights. Currently, FAA rules restrict or prohibit these restraints during taxiing, takeoff, and landing, requiring infants to sit unrestrained in a parent's lap during these critical phases of flight. The legislation would eliminate these restrictions and give adults the option to use their own approved restraints to secure infants during these periods. The bill affects all commercial airline passengers traveling with infants and applies across multiple FAA regulatory sections governing different types of aircraft operations. No specific funding is allocated in the bill, as it primarily requires regulatory changes rather than new spending.
