I am soon flying Sydney-Oahu-Kauai-Oahu-Sydney with Hawaiian Air all the way. I'll change flights once I get to Honolulu for Kauai & return. I'm aiming to take my 8'6 PSH & paddle over. The Hawaiian Air website & paperwork says it's fine to take it over & back, with a charge of $50 or so for each leg of inter-island flights.
I just thought I'd get your advice on whether this seems right to you, since I had unexpected costs last time I flew Hawaiian Air & a seperate inter-island aircraft.
