Re: Future of the A319NEO in Airbus portfolio

Like the A320, the A319 could've used a two row stretch when they went NEO. It would not have sold great, but probably at least some. In hindsight there would've been less overlap with the A223 as well.

Re: original wing(span) of the 787-9

Thank you. From that thread at the bottom: 62.1m for the 787-9 vs 60.2m for the 787-8.

Wonder if that is any indication for the scope for the wingbox to cope with any wingspan increases related to MTOW increases of possible future developments of the 787.

original wing(span) of the 787-9

If I remember correctly the original plan was for the 787-9 to have a slightly larger wing(span) than the 787-8 and that because of reasons like cost and the performance of the 787-8 having proven to be sufficient, Boeing stuck with the 787-8 wing. Does anybody know the specs of the original wing Bo...
