Onan!
I have to agree with the thought that onan is a gutter journo looking for scraps. In 30 years of flying I have never heard of anyone being unduly pressurised to take the absolute minimum fuel on each and every occasion. We, in our moderately large airline here in UK, do have a carefully researched and well written fuel policy booklet but nowhere does it 'tell' us to stick to the PLOG fuel, regardless. It does point out, as you might expect, the costs of carrying extra fuel (moderately expensive) against the costs of the annual diversion rate (quite small)
Having said all that, I find on our European routes, using the longest SID and Star we almost always have a buffer of a few hundred kilos which gives one a warm feeling of confidence!
