No, I'm saying planes often fly with less than a full tank, when it's
not needed to fly to the destination. If a plane takes of with a full
tank of fuel, when only half a tank is sufficient, then they're carrying
all that fuel at great expense and may also decrease available payload.
Don't forget, fuel consumption depends on weight, so if they carried
far more fuel than they needed, they'd burn significanly more fuel to
carry it. In that Gimli Glider incident, they goofed in calculating how
much fuel they needed.
