The aircraft was B789 VH-ZNE that arrived PER two minutes early on Thursday 17 January 2019 on QF9 ex MEL. Naturally as at 1300 AEDT on Friday 18, it remains on the ground in Perth.
QF10 will still operate between PER and MEL on Saturday 19 January.
moa999, if my memory is correct, QF10 has been cancelled at least once, but I don't recall QF9 having been given the chop. Your contention may be correct. Too hard for me to search 100 plus pages of this thread covering since these flights were rerouted via PER. Unlikley that all of us would have missed any previous cancellations of this very high profile flight.
Normally journalists are able to obtain passenger loading numbers from airlines when flights are affected (or in an occasional worst case, when there's an accident). The QF sensitivity must be because it is finding it hard to reacommodate passengers on other flights.
The relative claiming one passenger has been asked to wait three days seems credible given that this route is only daily. One wonders if QF is using EK to try to accommodate some of the stranded passengers? I bet not all are on flights ex PER by tonight.
The delay must be not just because parts have to be flown from MEL to PER, but the installation time and then the OK to again operate. That plus no replacement crew available in PER, and the existing crew out of permitted hours surely make it impossible to solve by say 0600 this morning PER time.
BITRE figures indicate that about three quarters of 'the 9/the 10' patronage' bound for or coming from LHR originates or finishes their journey in PER. not MEL, as the number of passengers shown making MEL - LHR journeys (only possible in the way BITRE records these to be on QF9/10 as all other options including QF35/QF36 or Asian/Middle East competitors require a change of aircraft).
It's an even greater headache for QF given that there are fewer airlines offering flights to PER via other hubs than is the case ex or to MEL or SYD.
