Sorry Tuner,
Yes I see your point.
If the tech crew costs savings are a MAXIMUM of 1.6% then the fuel savings of 25% are insignificant compared to the imperative to obtain a B scale for pilots flying it.
So the question therefore, is that if the margin is that thin, then what are other groups such as the executive doing with such a burden?
Or does ideology dictate savings can only come from pilots?
I.E it is good enough for one group but not another?
What grants them immunity from this margin you profess to know to the %
