Is it that hard not to book the JQ flight? Or are you drawn to JQ whenever it is presented like a dog is drawn back to its own vomit? Do you need to join JQA, that is JQ Anonymous for those who cannot help themselves but to fly JQ? Perhaps you should consider using a different web site or a travel agent if that is the case.
Regardless;
The JQ 332 has the exact same pitch as the QF744.
QF FF get lounge access when flying JQ in the same way they would have when flying QF
The entertainment of JQ may actually work and if you get an iPad may have more content than the old QF744 and the prone to freeze Rockwell Collins system
It is made very clear which flights earn FF and which do not on JQ and how to get points
QF don't sell codeshare/ JQ business class so your rant must be about travelling Y
