Idea for back-up plan. www.2hawaii.com Pleasant Holidays sells AIR ONLY (on ATA). They currently have your travel dates available (out of SFO) for $418 RT. PHH fares don't fluctuate too much and they don't have the same advance purchase rules that major airlines have. Only hitch is getting from PDX-SFO cheaply.

I have used PH several times over the past 20 years, including for a group airfare booking last June for our family/friends to travel to Maui for our wedding
