ok then.......forget QF comparison.
Back to the EK comparison
2 x 777-300ER's on a 13 hr DUB JFK trip burn 210.6 t or 268,280 lt
Payload for both = 121 t ( I've upped the wt to dry op wt )
602 pax ( 3 class )
60.8 t cargo
= 445 lt/ pax
1 x A380 on the same 13 hr flight burns about 169 t ( according to A380-800 )
or 215,286 lt
Payload = 66 t
489 pax ( 3 class )
17.1 t cargo
= 440 lt/pax
So, the 380 just edges out by a wisker the 2 777's for fuel economy but is not close to the amount of cargo or pax carried.
So, as I said it comes down to the economy of 2 A/C instead of 1 and how much revenue you get from an extra 43.7 t of cargo.
Nighty night.
