No slam taken, but you need to research the truth:
PHX: KONA on HI 31 Mar rtn 12 Apr RT coach $1150ish, Business $1,870
Delta, same dates and destination: Economy RT $1450, Business class $3,700 And they use HI as interisland transfer.
Not an LCC? Think again.
Hawaiian averages higher fares than any other airline. That came from an investor presentation by the company. You can't hardly expect comparing one day says anything. Fares fluctuate more than my first wife's moods.
Hawaiian attracts it's customers primarily because the are "Hawaiian". Not because they are perceived as being a low cost ticket.
