IMHO it's also amazing how often a newbie is "welcomed" to FT with a variety of less than encouraging responses, some highly experienced and well informed regulars find time to criticise a newbie rather than either answer the query or simply move onto the next thread if they are disinclined.

Not everyone's data mining skills are crash hot, they might not be across the basics (of fare classes), might have "innocent" expectations about how an airline like QF treats its FF'ers.

IME most folk have very low levels of knowledge on FFer matters. I am also sometimes surprised to watch some other folk, for example, in the scenario of seeking to validate facts in a "bar discussion" (even with high levels of education and a great job) struggle to "Google" information on demand.

Incidentally, data mining isn't always easy when you don't know what it is you don't know!

In this specific case the QF calculator has not been programmed to return data on the search criteria of KUL-SYD in MH in business. Some twit at QF has loaded the program without that capability! So the OP has followed the usual process of checking on the QF website, locating and applying the earning calculator, which would work in the majority of cases.

Looks to me like QF should get the criticism here, not the OP.
