On the weekend, I had a look at some fares MEL-HNL for some relatives (via SYD of course). In comparing fares, I did notice that flights on QF metal were not that different in price to flights booked through JQ on JQ metal. However I did notice that flights booked on the QF website using the QF codeshare on JQ metal cost $200 more than exactly the same flights using the JQ code booked through the JQ site. It is clear that flights booked using the QF codeshare do not earn any QF points (apart from the 2000 pts on the MEL-SYD/vv sectors) and further when clicking on the flight details it indicates that Meals are "Available for Purchase". Which makes me think that ignorance would be the only reason anyone would book such flights. Any other reason?
