How should I properly install my car seat on an airplane?



All of our rear facing car seats are certified and safe for use on an aircraft. Convertible car seats are certified and safe for use on an aircraft as long as they are used with the internal 5-point harness. 

When installing your approved Safety 1st car seat on an airline, here are some tips to follow:

  • Install/use your car seat only with FAA certified equipment.
  • The car seat should be installed in the aircraft seat in the same way that it is installed in the vehicle with a lap belt.
  • Use on forward-facing aircraft seats only and in a position where the lap belt can be tightened securely.
  • It is suggested to install the child restraint in a window seat to avoid blocking the aisle. 
  • If the aircraft lap belt is too short, ask the flight attendant for a belt extender.
  • Store lower anchor belt and tether strap when using aircraft belts.
  • It is always advisable to contact the airline for their specific policies prior to taking a car seat on board.

Some airlines may ask to see a label stating that this child restraint is certified for aircraft
use.  There is an airplane certification label located on your child restraint as shown.

When installing your car seat on an airline, follow your manual for lap-belt installation.  Below is a general step-by-step guide:

  • Select the appropriate direction to install your car seat on the airline seat(rear facing or forward facing). Follow your car seat manual regarding age/height/weight requirements for installation via lap belt. 
  • Place the car seat on the airline seat flush against airline seat back.If rear facing, ensure the car seat is level-to-ground (based on level line located on side of car seat).
  • Route airline lap beltthrough the appropriate belt path for your installation.
  • Reach under pad and pull lap belt across the shell. Do NOT twist belt.  When rear facing, lap belt MUST be in front of the crotch buckle strap.
  • Buckle airline belt.
  • Tighten belt: Place hand in car seat. Firmly push car seat down and back towards the airline seatback while pulling free end of the belt to tighten.
  • Check belt tightness: Hold child restraint at the belt path with weakest hand.  Push and pull from side-to-side.  Your seat should not move more than 1” at that belt path.
