Some interesting predictions on here. This is my take, and it is based on what we need to replace, not how we are going to grow.

We need a few more 77Ws to replace the 744.

We need a 250-300 seat trans Atlantic replacement. The 330-900 seems to fit that role the best. Its ownership cost advantage, and not over engineered for that mission. The 787-9 does best on longer stage lengths.

Next is if the company wants to keep reducing 50 seaters or not. If they do the clear path would be C100. This way they can add more e175s.

I do not see the need to add even more 190 seat airplanes like the 321. The PS birds are old but not as pressing as other needs.
