If a child aged 5 to 11 is flying alone on Hawaiian Airlines the unaccompanied minor fee must be paid This fee is thirty five dollars for inter island flights meaning flights that stay within the Hawaiian Islands If the child is flying between Hawaii and the mainland United States the fee is one hundred dollars per flight leg So for a round trip that’s two hundred dollars total The fee is the same even if the trip is short or long Hawaiian Airlines lets two children from the same family with the same drop off and pickup people fly under one fee but if more than two kids are flying each extra child will need to pay the same fee This service cannot be booked online You have to call Hawaiian Airlines to arrange it The fee is paid at the airport during check in when you also turn in the required paperwork and show ID
