B777 Cost index
This is a question for B777 pilots. We fly B777-200ERs and the cost index initially started off roughly at around 120. Then some "expert" came in and decided to drop the index to about 18. Then he decided that, that 18 was not working so he took it back to 120.
I do understand that the cost index is variable and has a lot of things involved.....
Im wondering just what rough cost index do most of you fly on the B777-200ER?
