I honestly do not understand what is attractive about 5/4. Like the above poster states it is not for your benefit it is so they can maximise your productivity. I appreciate everyone's family situation and partners schedule is different, however I have never once been rostered 5 days of actual flying in a row at J2, I think I was rostered 4 once! Never done more than 2 sectors, it simply does not happen here unless you have to position an aircraft off an ASB.
I can book all of my kids school holidays off in a brilliant/simple online system with instant approval subject to the availability, which I can see on a separate page.
J2 is not perfect, but it's light years ahead of RYR
