Re the 787 the main concern for me is how well they can be repaired. Taking China Airlines 611 as an example, there are others.
That aircraft was damaged 22 years before it crashed but at the time of the first accident it was not repaired correctly even though
the damage was very clear.As I understand it the composite hull of the 787 might not easily show damage, damage which could cause
a major crash in a few years time. Now that is the reason why I don't wish to fly on a 787 not the battery issue.
In spite of my very original PPRuNe post moaning ( over the top on reflection 2 years on
) I like Air NZ. Snag is now however that
they are buying several 787's so I might have to fly with another non 787 airline.
