Some numerical values:

Althought he didn't explain his calculations, according to Tony Webber, former Qantas Group chief economist the costs of 2 extra kilograms per person are:

Mind you, this is for every person on the aircraft carry an extra 2 kgs. As an average Quantas A380 has 484 Passengers , and with 159 liter per barrel this will cost

$ \frac{3.72 \cdot 159}{484 \cdot 2}=0.61 $ Liter per kg taken.

Or €1.81 per kg taken, using Webbers prices.
