BOAC used to fly to HNL, en route to Tokyo.
I really can't see it happening. I go there for business but there isn't very much of that happening on any route going into HNL, the fares relate to the tourist trade and I can't see it being competitive or strategically interesting to BA. Best left to Virgin unfortunately. At the various BA events I've been to, and questionnaires I get, it has never been mentioned.
