Availability: October - early May 2017. Very select outbound availability however, return flight have more dates to choose from.
Search using Google Flights and book on Hawaiian Airlines or Alaska Airlines . This fare seems to be at least $10 higher on other travel sites.
My sample travel dates:
OAK-OGG-OAK May 11-18, 2017 (1 week) $398 on Hawaiian
SJC-OGG-SJC Nov 13-23, 2016 (10 days) $398 on Alaska
