In the army this kind of thing was called "Throwing smoke". That is, if something f*cks up and you've got the finger pointed at you, you make some extravagant counter claim that is completely off-topic and duck for cover while everyone talks about the counter claim you just made.
This all started with AJ complaining about something that happened well over 12 months ago. Why? To take the pressure off him due to the high amount of SYD-CBR cancellations.
CBR airport went public with the cancellation rate. Rather than address the issue of cancellations (i.e. the fact that Qlink turboprop and 717 operations have crew shortages, as well as the 717 debacle late last year when due to management, four 717's were grounded in CBR), AJ simply tried to divert the issue by bringing up something that happened over a year ago.
Judging by the debate going on here, mission accomplished.
