How to improve or redisign the airbus A350?

Question

Making the A350 better than the B787.

Answer 1

Put headers and cherry bomb glasspacks on that baby! oh, and flame stickers on the front...

Answer 2

Maybe try to avoid using titanium fasteners that even a huge multinational corporation like Boeing can't manage to get its suppliers to make on time to support production.

Of course Airbus needs to make sure everyone's using the same revision level on their software . . .
