Best guess is that Qantas may know that it's an inefficient use of the aircraft's time. But they couldn't get the slots for a morning departure.

Obviously. But i seem to recall that the aircraft used for project 'sunrise' would have a regular economy cabin.

I suppose that it was a matter of time before Airbus would bring this up. With Singapore, only doing Business and Premium Economy on the 900 ULR. Airbus would need to work extra hard to sell the 350 to Qantas.

And this is why i carry my valubles in my pockets on a flight.

The distance between Sydney and Beijing is 8943 kilometers. The A330-300 has a range of 11,300 kilometers. Therefore the 300 has the range to fly the route.
