Complaint Review: HAWAIIAN AIRLINES

I want the traveling public to know of the deplorable service my family experienced at the Kona International Airport at the hands of the Hawaiian Airlines ticketing  agents. Hawaiian Airlines is de facto  the only inter-island air carrier these days, so they have a monopoly on the business. 
Despite pre-printing our boarding passes and despite showing up an hour before departure, we still missed our flight and in turn missed attending a very important meeting. The "topper" was the fact that 10 minutes before departure, they realized that several of us were still in the non-moving line ( several different Hawaiian departures were all herded into the same boarding line!), and proceeded to personally escort us to the gate. Great assistance, service and professionalism-- or so we thought.
It was like the Three Stooges- they were on walkie-talkies to the gate and the plane the whole time, BUT when we got to the boarding area, they told us that the plane just left!
No apologies, no assistance, no chain of command to complain to. 
Total arrogance and condescension. The old "take-it-or-leave it" attitude. "If you want to get there, we're you're only method of doing so, and we couldn't care less about your troubles or concerns."
