At what age does a child need to have their own seat on an aircraft?

A child is required to have their own seat on an aircraft starting at the age of 2 years old. This regulation is in place primarily for safety reasons, as children who have reached this age can no longer sit on a parent's lap during the flight. An individual seat ensures that they are securely restrained during takeoff, landing, and turbulence, which is vital for their safety.

In many airlines, including Air Canada, this age policy is adhered to, and parents are encouraged to book a separate seat for their child aged 2 and older to promote a safer travel experience. This helps in managing the cabin environment better as well, ensuring that there is enough space for every passenger.

The other age options do not apply for requiring a separate seat: infants aged 1 or younger can typically sit on a parent’s lap, while children older than 2 must have their own seat. Therefore, recognizing age 2 as the correct threshold helps align with airline safety protocols and passenger comfort.
