Working for an ACMI Operator, it is frequent that client airlines demand to know why any fuel in excess of CFP requirements is carried. We have no problem providing this information. It's called professionalism, guys!
Regardless, it is up to the crew, how much, if any, extra fuel is carried.
Maybe, if the bean-counters had to justify "extra" fuel carried in their Jags or Benz's on their way to deposit their paychecks..... hmmmmmm?
I stand by my first flight instructor's admonition that
"the only time you have too much fuel is when you are on fire"
Cheers
