How to avoid seing JQ "business" when search classic rewards on QF website?

This is it - when searching "multicity" to see what is available for whole month one can see "business" but upon opening it reveals that this is JQ "business" that in fact no more than PE. And while flying to, say, SIN in JQ business is OK (it is day flight) flying back is not that OK because it is overnight flight. So how I can see only "true" business in my search?

Fly with a reputable airline.

The worst is when they show business class for a domestic leg and then the international component is on Jetstar economy when searching for rewards in BC to Asia. So an hour in Qantas Domestic Business then 8 in Jetstar economy.

You can't, you can tell for Singapore because it will show cheapest business points ticket as 51,300 for JQ7 / JQ8.

They charge considerably less points of Jetstar business, so they are accepting that it is a far more inferior product and likeable to Premium Economy.

I have tried all sorts of ways to delete JQ from all of my searches with no luck, even when you only have the Qantas tab highlighted on the flights selections JQ are still there, it’s like a disease really, can’t get rid of it. I have also noticed that since classic plus started so many classic rewards are now Jetstar flights and QF are all classic plus which is not surprising, the whole business is fast becoming Jetstar, with some planes having a roo on the tail.

use a paid search engine instead of QF website, well worth it.
