757/767 cost index
Sorry if this has been covered in the past,
We have been operating a fixed CI for the last 6 or 7 years- it came about to give a sensible(280+ kts ) descent when fuel was enormously expensive. Obviously this was a bit daft considering the descent is only a minor portion of the flight. Finally things are starting to change,but I was looking for any info on how other airlines operate with regard to CI/econ (or not) and any useful links anyone might have,
I didnt make the rules,before anyone launches off- I can see its not the best idea in the world!
Thanks in advance
