EK actually manage ok at NCL with the 77W, cargo is nearly always full and pax are averaging about 65% lf which is increasing quite quickly now. On the first flight for the 75th anniversary the aircraft had 419 passengers on and I think it had quite a bit of cargo and that was ok too. Fuel tanks will only be about 50% full if you think about it, that saves a couple of tons.
How about LS, LBA-ISB with a 767/A330
