They’ll pass on the 321neo and wait on the max 11 to give everyone something to Grumble about.
I doubt that Boeing is going to make the 797 any time soon and there isn’t really a cost effective replacement for the 767. They may be forced to buy a bunch of 787’s to replace the 767 flying. The 321 neo’s may turn out to be an efficient replacement for the 757 fleet if the price is right. We’ll have our answer about the time the Florida base opens.
