Yes you are right about the cost over run around $3.0 Billion…
divided by close to 1000 airplane back log will amount to 2%…not too bad for a superior product that will save better than around 10% in airlines operating cost in fuel alone…:k:
If you are travelling to Newzealand this coming Jan, the 787 will not be in service, you will most likely travel by 777.
Good Luck!
