Yes, that's a fair comparison. Someone has a comparison between a 330 and a 777?
One has to understand that Airbus designed its A340 before Boeing began boosting its Etops limitations. Before that, lots of flights were economically not useful with a twin. That's why Airbus should have started selling the A330 as the standard long haul type, whith an A330-500 and even -600.
