The safest place for children on an airplane is in a restraint such as a car seat. The FAA strongly recommends that parents and guardians secure children in an appropriate seat based on his or her weight and size.
Travelers should fasten their seat belts immediately after taking their seats. The belts should remain buckled during the flight whether or not the "fasten seat belt" light is on. The belt should rest snugly and low across a passenger's hips.
An airline seat belt's average length is 46 inches, according to Alaska Airlines. For those who do not fit in a standard seat belt, an extender may be requested from a crew member or bought from retailers such as Amazon.com.
