So HA does the flight I think 3 times a week, departing HNL Tue Thur Sat, return Weds Fri Sun. Yes you can get miles on flights from HNL to SYD on HA in the higher fare classes. Though it's much more expensive. My BF was going to try to get miles but was $1800 FT from HNL for fare classes that you could get miles vs $550 without. He there for is going to do LAX-DL-HNL-HA-SYD and the same return, $550 on HA without miles then $319 on DL with miles.
