Can the Extend2Fit be used on aircraft?

This child restraint is certified for use in aircraft when using the harness system on forward-facing aircraft seats only. 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.
