I flew into OGG +/- 20X last year and gate space is a super-common issue. I've personally waited an hour+ when arriving and once saw my arriving plane (that I was set to depart on) wait for over two hours. One quirk with Alaska is that, for whatever reason, they absolutely REFUSE to change a gate. Planes will sit on the runway for hours while other AS planes come and go from other gates. I suppose delaying departures is a (small) step in the right direction as I'd rather sit in an airport than on the runway after landing.
