- DOW 299t vs. MZW 366 is 67 tons payload, (big difference, sorry).
- Both aircraft are 3 class configured in similar proportions, meaning naturally that there are more high yield pax on the AB, but again: proportionally.
- no additional fuel on both flights.
The A380 might carry more luxury deadload and it might even be worth it. But AB propagated it beeing the most environementally friendly bird - looking at the burn vs. kg or pax in it's current versions on SQ or EK it seems simply not.
