"You loaded max fuel available at that density and landed with near minimum for the conditions. If you loaded more freight you would have had a higher fuel burn, so you could NOT have loaded anything more in either fuel OR freight!"
Intruder,
So let me get this straight ... The maximum that the 744 can operate is always 30 tonnes below the MGTOW? I think you may be mistaken.
Nowhere did it say that max fuel was loaded. None of the figures quoted above are maximum weights except for the MGTOW of 396,893. They were actual weights for that flight.
Certainly the burn will be somewhat higher with additional payload, but the point is that that flight could have carried 30t more fuel and freight - no matter how that combination would have been divided up it is still unused capacity.
