Is the Graco 4Ever Extend2Fit car seat approved for use on airplanes?
The car seat is certified for use in aircraft only when used with the internal harness system, and only on forward-facing aircraft seats. It is NOT certified for use in aircraft when used as a booster seat because aircraft do not have shoulder belts. Contact the airline for their specific policies.
