Overrun
"I'm sure no-one over 6 foot tall can stand up straight in an Airbus toilet in any cabin class." - I am exactly 6 foot tall and I have never noticed a problem with the height of LH's or AC's A330 toilets. I also find the cabin quieter than any other plane beside the A340, but then I have not flown in a 777 yet.
"Evaluating the suitability for airlines outside the G8 countries. The 777 wins hands down." - Care to elaborate? It boils down to cost per seat for a given route, inside or outside the G8, doesn't it?
I must admit I am surprised by these numbers. I would have thought the 777 to be more efficient. After all, it is a quarter generation ahead...
