Saver award availability either to or from HNL during high season=never a good time to book. The laws of supply and demand state that a high coach fare is more desireable to an airline than the lower of the two non-revenue generating tickets. You want to return to Hawaii during Christmas break, when there are blizzards in the mainland, and familys can take vacatoin, and use the non-standard award? I'm not trying to be rude, but if u find ANY date during Christmas break, I advice taking it.
DOH I didn't see the 2006 part...331 days out is earliest, and still, take ANY seat you can find, if you are lucky enough to find it.
Good luck
