Chase and Hawaiian Airlines

I like using my Chase UR points for first-class tickets as normally I won't spend the cash on such a luxury. I live near Sacramento and there are only two airlines that fly direct to Hawaii which are Hawaiian and Southwest. Southwest doesn't have first/business class and Hawaiian isn't on the Chase system. I can sometimes transfer points to JetBlue and get Hawaiian flights that way but they charge more points for the flight and very few flights are available.

Does anyone have any ideas on the best way to handle this? I could fly United but then I have to bounce through somewhere like SFO and that turns a five-hour trip into a nine-hour trip with multiple planes and layovers which kind of defeats the point.

I guess I could switch over to the Amex platform but I like keeping my points all in one system.

Thoughts?
