As far as I'm aware the LHR reschedule was to "best suit business travellers with early morning arrivals..."
I've heard that line before.
And it was, is and always will be b0llocks.
As a business traveller, I f

hate early morning arrivals. Can't check into a hotel, so I feel tired & scuzzy all day. Just what you need walking into a meeting, to know you're half asleep...
Aus - Europe you're going to miss a day no matter what you do. Better to arrive at night, get a feed, a decent sleep & kick off the next morning in some kind of reasonable shape.
So QF tin the 32 and say "here SQ, here's a full A380 load of punters that we don't want any more".
