Will my infant need a car seat on an plane?
Ultimately the answer to this question comes down to how important your baby or toddler's safety is to you.

The Federal Aviation Administration (FAA) does strongly recommended that you use an approved child restraint device when travelling with infants less than 2-years old. Car seats are the safest and most comfortable way for infants to travel on a plane. But, in saying all of that, you are not legally required to use a car seat on the plane, so it does come down to your own decision.
Here is the FAA Baby and Toddler Car Seat Regulations for Airplanes:
For a child less than 40 lbs. : Secure your child in an FAA approved car seat for the duration of the flight. Follow the manufacturer’s instructions. This would typically be in the rear-facing position.
For a child 22lbs – 44 lbs. :The CARES Child Safety Device is the only FAA approved harness restraint for children weighing between 22 and 44 lbs (kids 1-year and older). The benefits of a CARES harness is of course that it is small and portable enough to carry in your carry-on bags. The negatives are that your child will be required to sit up pretty straight on the airplane seats and the harness is really uncomfortable to sleep in.
