I want to clear up something. Many people do not know the 787 competes with the A330Neo, the -9 and -10 compete with the 330-Neo. the -8 is by itself.
The A350 competes directly with the 777. here is a comparison chart.
The 777-300ER Absolutley dominates the A350-900ULR so here is it against the 777-200LR.
Boeing 777-200LR Worldliner versus Airbus A350-900ULR
Here is the A350-1000 against the 777-9
here is the 787-9 Up against the A330-800
Here is the 787-10 against the A330-900
That’s kinda not even…
But people don’t know its the 777 VS A350.
