Airbus appears to be dismissing the possibility of a further stretch to the A350, despite the capacity gap between the A350-1000 and the A380 (as shown in this Boeing´s chart).
The A350-1000 will be capable of seating 350 passengers in a typical 3-class configuration. High-density arrangements could lift this to 440. And the A380 has configurations of 400 to 525 seats.
While Airbus positioned the A350-900 as the central platform for the 3-member family, the backlog of the smaller A350-800 is eroding in favour of the larger variants.
Airbus does not see room for a further stretch beyond the A350-1000; "A double stretch has never been shown to work in this industry," claimed Airbus chief operating officer for customers John Leahy, speaking in Toulouse on 16 January. "We couldn't do it. And we don't think [Boeing] could do it either."
The A350-1000 underwent a redesign in 2009 to improve its thrust and range capabilities but Airbus resisted stretching the fuselage. The -1000 has yet to achieve convincing sales - a matter Leahy attributes to slot availability - but the aircraft has attracted orders from Cathay Pacific and Qatar Airways.
