Interisland connections look unremarkable provided you're not checking a bag (see the other thread on Hawaiian's interline policy if you are), but 71 minutes in HNL the first time through isn't going to give you much time in the Skyclub before you need to get yourself over to the interisland terminal. Better to go for the later HNL-ITO flight if the club time is important to you. Also keep an eye on the ITO-OGG and OGG-LIH flights. Initial indications seem to be that the OGG hub isn't working as well as hoped, so schedule changes wouldn't be shocking.
