If flight 9 is running late, HA will almost always hold the last OGG and LIH flights for the night, to make sure the connecting guests are accommodated.
True that. I catch HA9 every now and then and they do a good job of making sure guests are accommodated from holding the last flight to even asking everyone on HA9 to remain seated upon arrival to kindly allow connecting guests to get off the plane first so they can get to the gates. This happened to me once after a delayed departure from LAX...about a half hour before landing in HNL, the lead FA asked everyone who was connecting to the interisland flights to raise their hand. He then asked everyone else to look around for those who have their hands raised and to kindly remain seated once the jet arrived at the gate to first let those off who had connections. Thankfully, pretty much everyone did so and I was very thankful since I was on the last LIH flight along with about 8 others from HA9.
