The 777 is more limited on ULR flights than a 744.
Having flown both the 744 and the 777-300 on the SIN-LHR route more than once I think we have might have to agree to disagree (though obviously the 777 doesn't do so well in terms of backsides on seats).
Unless the purchase price of the 380 and 77X are reduced substantially, I doubt and large orders are going to be made soon.
Agreed.
