It seems that Qantas is starting to fly the A350 again to HK later this month....but only as they are short of aircraft.
They did this early in the year.... for about 4 weeks and i don't believe the 350 will be long on the route this time ether. I suspect the 787 next year on the route
The A330s are in all honesty pretty clapped out in the cabin and the food is not great either according to Australian friends.
