I seem lucky enough to work for an airline (at LHR) who never put pressure on Captains about fuel and who never question the fuel decisions of any of thier crews. When I did my command course, one of the trainers, now retired (Jenx, if you are reading this, thanks a lot) gave me the following advice. "Regardless of the what the company may want you to do, never load less fuel than you personally feel comfortable with." Any airline that creates an environment which means that skippers feel they shouldn't follow that advice is treading a dangerous path.
