a380 vs 777

Ok i will try again, i think my last try went astray.

I will post some interesting fuel burn comparison figure re 380 vs 777.

These numbers are for EK who operate the PW engine on the A380, but i wouldnt think the RR would be too much different?

Perhaps our pilot members can add coments.

And remember QF operate A380 on long hauls !
