On commercial flights in 2026, the seatbelt rules for babies depend on whether they are traveling as a "Lap Child" or in their own seat. If a baby (under 2 years old) is sitting on an adult's lap, they do not wear a standard aircraft seatbelt; instead, many international airlines provide a "Loop Belt" (an extension that attaches to the adult's belt), though this is notably not permitted by the FAA in the United States due to safety concerns during sudden deceleration. For the highest level of safety, the FAA and the American Academy of Pediatrics (AAP) strongly recommend that parents purchase a separate seat and use an FAA-approved Child Restraint System (CRS), such as a car seat or a CARES harness. In these cases, the baby is secured with a multi-point harness similar to a car's. Babies who are unrestrained are at significantly higher risk of injury during severe turbulence, which is why aviation authorities are increasingly moving toward recommending that all children, regardless of age, have their own restrained seat.
