It costs about 10kg of fuel for an extra ton of fuel on an hour sector. Ie sweet F.A.
To put in perspective to carry 2 hours extra fuel over destination costs you about 40kg or 1 minute of cruise fuel.
It's ridiculous the drive to push min fuel when it costs so little for the insurance of extra fuel. (737 figures)
Or in dollar terms to carry 2 hours of insurance about $40
