I was on that flight two weeks ago and a similar thing happened. It arrived an hour late into KOA and left an hour late. Arrived in SFO and they tried to get people with tight connections off first. Luckily, our next flight was next morning. Unfortunately, a storm that passed through earlier that led to the delays, knocked out power to our hotel. The hotel did abandon us as they loaded us on the shuttle and sent us back to the airport.
