I don't think there's anything wrong with making sensible commercial decisions, with regard to fuel. It costs money, and we are duty-bound to be safe, but also commercially aware. I don't want my company to go bust, and despare of these morons who clearly don't understand fuel policy, and load extra on every sector, and probably not enough when they really need it.
I'll give you an example. The other day, I was flying back to LGW, late at night. It's a new company route, so no stats were available, and hence we were planned 15 mins of contingency. We had a very generous taxy fuel, for what was a very quiet airfield. I reasoned that we'd almost certainly get shortcuts on the way, probably a straight-in on 08R, and that we'd not need all that taxy fuel, so loaded 300 Kgs less than flight plan. Reserves were 2.2, planned remaining 2.8, and I landed with 3.4, as everything happened as predicted. Frankly, if it hadn't, my 300 Kgs that I didn't have, would have equated to an extra 8 mins in the air. Big deal.
All you are doing by loading extra fuel, is avoiding having to make a decision, which is what you are paid for. By all means load extra, when the weather is bad etc. But loading extra all the time "just in case" is pathetic, moronic, and you don't deserve your job if you do.
Oh, and do you ever fly with those idiots who load an extra 100 Kgs? What, exactly are you going to do with your extra 2-3 mins? As I say, I despare, sometimes.......
