From pax point of view, the new longhaul product looks great - but I guess still no crew rest on the 763 for you guys.
I did LGW-CUN with AMM last year - can't speak highly enough of the crew, who did their best to make it tolerable, but that 8 across/29" pitch config is a bugger for a 10hr+ sector.
The new fit will definately be the best on a UK longhaul charter (and looks better than some scheduled economy
).
