I believe some other carriers at times have lie-flat premium cabin service from the mainland to Hawaii on certain routes, but don't know what those are offhand.
HA is running lie-flats to lots of major airports on the mainland, including JFK, SEA, SFO, LAX, and PHX. UA has them from EWR and ORD, and AA from DFW. NYC to Hawaii is over 9 hours. That's longer than most TATLs. I'd certainly say J/F are worth the miles, if you can find saver availability.
