I'm still surprised though. Back then they were still trying to force the 380 to replace the 747 at HND (yes i know about the restrictions which QF was trying to get HND to change).
And surely they were already thinking about replacing the JNB 747 with a 380 potentially.
At this point, I don't think we'll see the 380s retire until QF gets a lot more planes. I'm sure there's a bunch of routes QF would like to try out or increase frequency if they had more midsized widebodies and 380s can free up 787/330s (like MEL-SIN consolidation).
