Personally I can't imagine driving 4-5 hours to get on a Dash 8 when you can be in ADL in an hour on Rex. I flew ADL-CED on ZL for work a few years ago and it's no better or worse than any of the QF Dash flights I've been on.
QF pulled this carp on us a couple years ago. It took a formal complaint to get us back on the original flight, which was then cancelled on the day 🤦🏻♂️
I have no issues with using my phone, but IME handing over a stack of paper BPs is infinitely easier when wrangling children than trying to scan multiples off my phone as the children do not have phones.
