Boeing 8X8 Series?
Airbus A5XX Series?
Airbus A5XX Series?
I don't expect much from Boeing in the next year or two. Boeing are in trouble. The 777x is behind schedule. Test flights just resumed but at best it will be six years between first flight and first 777-9 delivery.
Boeing 's new middle sized aircraft is supposed to arrive in the mid-2030. That is if they build it at all. It might be a 797 or it might never happen.
