Ahhhh HNL. One of the true black holes for non-revvers. Nonrevs of the female single kind have been known to go there for a flight and get married, have a kid and be divorced by the time they actually get on a flight.

Back ups and then more of them is the way to treat HNL unless you have access to detailed lists that show you stand a good chance.
I know on my carrier last October it took me 4 days to get through HNL as there were upwards to 100 nonrevvers each flight.
(Although I almost bought a USD99.00 one way web special on HA for a mainland flight. At that price for confirmed seating, why would you bother with nonrev if those sort of offers are still there?)
