So the A339 is far from being dead, good news.
The only place where anyone actually assumed it was, is here.
Like the A35K and 779, it's fairly poorly timed, as the bulk of the aircraft it'd replace (A333s and 772s) have either already been replaced, or are relatively new and still have another decade of life.
But there's really nothing else that sits in its portfolio area for the OEM, so very little reason for them to discontinue offering if any time in the remotely foreseeable future.
Airlines like TK, DL, CX, CA, MU, etc still have massive A333 fleets, that this aircraft could easily be called upon to replace.
Yeah but the thing with the 351 and 779 is that the plane they're aiming to replace hasn't entered it's mass retirement age yet. In around late 2020s, these planes should have a far higher number of orders than they do now. The A330neo on the other hand has an uncertain future as many big A330ceo operators have the 787 in their fleet and a huge chunk of A330ceo have gotten quite old already. So there's still a fair amount of chance that those airlines will just use the 787 that they already have to replace all A330ceo eventually.
Sorry, but that is not correct.
The 5 biggest years for A330 deliveries were 2011 to 2015, when over 500 were delivered.
There are 750 A330 CEO's less than 10 years old
You look at widebody deliveries overall, and there was a massive (possibly ridiculous) surge in the 2010's, with nearly 3,500 being delivered in the decade.
In 2013, 2014, and 2015, all 3 of the A330, 777, and 787 were in 3-digit delivery mode, or virtually so (99 in the case of the 777).
It is little wonder that widebody demand is particularly flat at the moment, for all types
