The OGG trip had a huge upgrade list and I had no chance of clearing a CPU, though I think we booked the trip fairly last minute. On the LAX-HNL trip, my girlfriend and I cleared into first at 48 hours before check-in. It was a very light load on a 753 and they only filled FC at the last minute, presumably with non-revs and buy ups. I know it's not exactly the route you are flying, but based on my experience, Hawaii routes are either packed to the gills and impossible to clear for upgrades, or they're half empty and I clear as soon as I'm eligible (FWIW, this is also my exact same experience with DL Hawaii flights; on SEA-LIH flight had 69 people on a 752 and we had 4 empty seats in FC).
