A330-200 has the same wing and fuel tanks as the A340-300 (the A330-300 doesn't have the centre tank). That is well over 100 (about 108 I think) tonnes of fuel. Only trouble with that is the payload with full fuel is you me and a lunch box! So TOU-MEL on a delievery no problem. I don't think the 777's (with possible exception of -200LR) are as over tanked.
