In response to jagoffee's post we did some research and found that HA changed most of their award classes last month. This is what is currently available via ExpertFlyer:

First - Flex Award/Upgrade - P
Coach - SuperSaver Award (Inter-island/Int'l) - U*

*Coach SuperSaver Award availability is only visible for Inter-island and International flights, not for Continental U.S. To/From Hawaii flights in our testing. If you find this not to be the case, please let us know.
