When travelling to Hawaii by plane, what documents do minors need?

If a minor is traveling to Hawaii by plane and it’s a domestic trip from another US state they usually don’t need a government ID Minors under 18 flying with an adult just need a boarding pass and it’s recommended to carry a copy of their birth certificate or school ID just in case If the child is flying alone they need to be registered as an unaccompanied minor for ages 5 to 11 Hawaiian Airlines requires a completed unaccompanied minor form and the parent or guardian dropping off or picking up the child must show valid photo ID For teenagers aged 12 and up traveling alone ID is not required but again a school ID or birth certificate is smart to have If the flight to Hawaii is international like from another country then the child will need a valid passport and possibly a notarized letter from the parents especially if only one parent is traveling Check with the airline before the trip to be safe
