Well, where I fly, we don't have ANY fuel policy
We take whatever we want to take, questions are NEVER asked, and we even have a new SOP that has us leaving the APU ON for flights less than 90min. We fly B737's all over Europe and make a LOT of money doing so.
Never understood and never will understand people who take less fuel then the PLOG only to be more "economical". Remember that a diversion due to low fuel always costs more than a couple of hundred kg's extra weight. Not to mention different fuel prices over Europe...(why land with min. fuel in Ljubliana for example when you know that the fuel there is 40% more expensive than in Germany?!).
Be reasonable, realistic but don't ever just bend to the beancounters just because they say so when dealing with fuel and safety issues. If you do THAT, then you are not flightdeck material. The PIC has always the ultimate say.
