Saturday : From these four cancellations of QF9 MEL-PER & QF10 PER-MEL : yesterday's QF10 PER-MEL sector, today & Sunday's QF9 MEL-PER sectors and Sunday's QF10 PER-MEL sector, it appears that the delayed QF10 LHR-PER (B789 VH-ZNI) operating as QF7010 arriving in Perth at 19:45 AWST this evening, 32 hours 5 minutes late and today's QF10 LHR-PER departure (B789 VH-ZNE) which is currently showing an 8 hour 20 minute delay, will turn around in Perth and operate today's and tomorrow's QF9 PER-LHR flights respectively, with the following delays ...
Today's QF9 PER-LHR is currently shown as delayed 1 hr 25 minutes with a revised departure of 21:15 AWST - a 90 minute turn around for VH-ZNI, while tomorrow's QF9 PER-LHR is currently showing a 1 hour 40 minute delay for a 21:30 AWST departure, also with a 90 minute turn around.
In the past where a B789 turn around has occurred in Perth, Qantas has operated the QF9 MEL-PER & QF10 PER-MEL sectors with A332's, so not sure what happens for those passengers booked from/to Melbourne on these flights.
