Thanks, it is clearly less work,
Your company's policy does mean it is less fuel. However, I guess there must be a limit... I mean, would flying at KT220 for 150 NM out be less fuel? Of course, I always mean clean acft, if you lower flaps or anything I am sure it is more fuel.
I know it is not the same, but with a car you do need more gas if you go 20 mph than if you go 55 mph...
