As a pax (but FSX experienced) it concerns me that less fuel=less weight=more profit. Where does safety come into it, can a Captain insist on having adequate reserves of fuel? Is there pressure in this current economic climate to cut corners? If a Captain has to declare a Mayday due to insufficient fuel, is their employer going to stand by the Captain and say they were complying with our SOPs? I doubt it, they will say Captain is solely responsible for the safety of their aircraft. I would rather pay more for my ticket and get to my destination (or near to my destination e.g. Ryanair) in one piece and I'm sure most pax would say the same. Wasn't there a fatal crash in the U.S. a few years ago due to lack of fuel, and the crew not making enough noise to atc they were running out of fuel?
