Three years ago we were using cost index's of 150.
As the price of fuel has gone up the cost index has come down.
Today we are using for the:
B777-300 CI 75
B777-200 CI 65
These cost index are the same whether long haul or short haul and our sector's range from 30 mins to 16 hours.
In my experience on the B777 any speed below .83 doesn`t save fuel and there has been another thread running with the BA guys in the main forum, discussing this.
