Extensive studies by CX have shown that a CI of 20 does save fuel on long flights ( 15 hrs )
It wouldn't be too hard to examine the results of CI 80 flts v CI 20 flts on the ER with 6 ULH flights per day for the last 8 months. ( 1,440 flts, of which every one is tracked ) And this is just our ER fleet.
So don't go getting too involved or worried over it, just do it !!
