I think if they airframe could offer a stretch and with new fuel efficient, 7E7 technology engines, they might have themselves a winner. Yes, it will NOT compete with the A380, but possible create its own little niche market in the pax market between the 777-300ER and the A380.
Yes !! Even Lufthansa is looking for a plane between 744 and A380 !! They are absolutely interested in a plane of that size. Guess some other airlines like e.g. Singapur, AF
, Emirates; Quantas would be, too. Of Course not to mention non A380 customers like BA
