I'll be the odd one out. I fly BNE-CNS every week or two. I much prefer QF J to VA. To the extent that I only slightly care if I am Y or J with VA. I guess it's all about priorities.
Lounges - I rarely use. I only take carry on, and I rock up to the airport as close to boarding time as possible.
Seats/legroom - I'm short. I can comfortably stretch my legs out in Y, so not really important. I do have a substantial bum, so J is obviously more comfortable, but I still fit comfortably in Y seats. VA doesn't have leg rests. I love my leg rest! Same with lumbar support. Not a necessity, but I like it.
Food, I much prefer QF's choices.
The single most important factor for me... pillows and blankets . Whenever I get on a QF flight (J or Y), the first thing I do is ask for them. In Y on QF, you get a thin blanket and thin pillow. In J, you get an awesome doona style blanket and nice fat pillow. Ocassionally some lovely FA will get me J blanket and pillow when I'm in Y.
VA don't do blankets or pillows at all on flights less than 3 hours. So I have to take an extra backpack with my own.
I always sit window and never go to the toilet on planes, so the toilet traffic from Y doesn't bother me. I have seen a FA send a Y pax back before though.
So yes. Minimal attraction to J on VA for me. In fact, if my choices were Y window, or J isle, I'd choose Y.
