Agreed this does not appear to be a UA issue. And Near Misses (aka Loss of Separation) do happen more than people think due to how a near miss is defined.

But a Near Midair Collision, which occurred at EWR earlier is a different story. Those are more rare and more dangerous. I do not know if they have classified the Hawaii incident as a Near Miss (loss of separation) or a Near Midair Collision. I think they are still reviewing. But it it also was a Near Midair Collision, then having 2 of those a few weeks apart does concern me.
