Well if you re-read my posts above I did say that any final comparison will depend on the overflight and landing charges. The 380 would lose money half empty ( 245 pax ) for sure and 1 777 would kill it ( 245 pax ).
So, yes I say that POSSIBLY 2 777's are better than 1 A380.
I don't want to start comparing 2 330's to 1 777. Off the top of my head the 330 would possibly win.
