Have not flown QF domestic much in recent times, so happy to report that 4 out of 4 (including one inadvertent one at a port that does not do it) PBs were passes today.
QF408 (MEL Gate 24) - approached after call in lounge, two lines of about equal distance, did not look good. Just after joining one of them I spotted some people heading down what I discovered was a somewhat obscured PB lane - however I went there and it was perfect.
QF790 (SYD Gate 7) - again, approached after call in lounge - perfect - long single line for general, PB line next to it with no-one in it
QF791 (ASP Gates 7/8) - this was the accidental one. Gate 7 was showing on the monitors but they were boarding through gates 7 and 8. Gate 7 had a long line but after I came out of the QP there was a long line at gate 7 and no-one queued at gate 8, just breezed through
QF451 (SYD Gate 13) - as I got off my ASP-SYD flight I noted boarding happening at Gate 10, and the announcement was very specific about who should use which boarding lane (i.e. J pax and WP/OWE pax in the left priority lane, the rest in the right lane). And this was exactly the announcement we got when boarding at Gate 13. And that is the way it worked.
Don't know if QF is generally lifting their game here, but all positive today for me.
