Please don't get me wrong, I meant the A330-300 only, and again only on flights longer than 9 hours. As far as I know Air Canada uses its A333 only from and to YYZ and YUL which can be reached in less than nine hours, but well, I'm not sure about the MUC-YYZ flight. LTU used to fly the A330-300 to the Caribbean in the winter months but they suffered from payload restictions.
Nevertheless, the A333X can do long hops now and there will definitely be more airlines to use that advantage. But that could also weaken the A343's position.
