For sheer convenience, I'd fly the Hawaiian Airlines direct flight to Honolulu. No connections, decent seats. You can also earn JetBlue miles booking it on Jetblue.com which is a nice way to get some points. Given that you're usually out of JFK/HPN, JetBlue is a good option for tons of flights p much everywhere. I'm biased because I fly p much 90% of the time with them.
A direct RT is about 780-820 right any day of the week.
You can get inter-island pretty easily and as Xno said, the other islands are a bit cheaper and honestly nicer.
