For me, when I do it, it will be a mark off my bucket list, something to try.
If they (Qflink) is still flying the E190 BNE - ADL, I would probably go with that, even tho they are very old now, have done to 2 J and QP lounges at BNE, and prem sec screening, so that part is done.
Cheaper I guess to go MEL - CBR in Y, on the A220 (in my case), then CBR - ADL in an E190.
Wish they would bring the A220 into MEL - ADL several times, just for me to try it.
