Interesting post from

It seems that Airbus is
not offering a ULR A350-1000. Boeing is in a tough spot right now as they are seemingly unable get the 777X off the ground in time. Airbus seems to be taking advantage of this. After all, why engineer a bespoke plane for one small customer?
It appears that Airbus will offer a weight restricted A350-1000 with minor efficiency improvements. Given at Boeing isn't developing the 777-8 at all at the moment it seems that Qantas may not have any other realistic choices.
What's missing from that article is the detail that (as everyone reminds me) AJ has said there will be an F cabin on the Project Sunrise aircraft.
So the QF configuration will be 4 class not 3 class, and should have even fewer than the 300-320 the article envisages.
The A350-1000 cabin is only 5 inches wider than the B787-9 cabin so that won't make a huge difference and I can't see QF doing 10 abreast in Y on this aircraft.
It is 11 metres longer. It seems to me this doesn't offer the chance to do much more than add an F cabin of 12-14 seats similar to the A380 F cabin.
Adding that to the 789's 42 J, 28 PE & 166 Y would give you about 250 seats.
If you made the F cabin much smaller - say as few as 6 seats - then being optimistic you could increase the J seats by about 16 or PE by 21 or Y by 27.
Or some combination thereof, which might be influenced by doors, bulkhead, galley and toilet placement.
Of course extra toilets and possibly galley space dedicated to first would eat into the room for extra seating.
But on these rough calculations you would be looking at between 250 (14 F), 258 (6F, 58J) or at most 269 seats if you have an F cabin at all.
You could squeeze more in but that would be inconsistent with AJ's stated "premium heavy" aproach.
At 270 or fewer seats the range of the A350-1000 would be looking pretty good!
