The 764 fuel usage is just a little bit over a 763, which was shown from the tanker contest to use 1000 lb / hr less than A332F. So it's highly unlikely that a 764 is less fuel efficient than an A330. Payload is not an issue, the charts show 55 tons (50 metric tons). But range is an issue. The wings are an issue, the 767 optimal cruise is M0.8, versus M0.83 for the A330. And the 764 does not have a real big brother, which the A332 does.

764 has 13t higher OEW, 16t higher MZFW. (+ ~18%) you won't get by with "just a little bit over a 763".
As I shew further up the 764 needs ~6% more fuel around MZFW than the A330.
the A330 will fly further (~500nm) due to higher MTOW. for same range the difference will be bigger.

Delta ordered the 764 as a replacement for the L10 (not L15) to use primarily on high density domestic US routes. IIRC it wasn't until several years later that they deployed them on TATL flights.
Correct. It flew mostly Hawaii and Florida flights(maybe some Carribean too?) in a high density configuration before they were retasked to international flying.MrHMSH wrote:I'd batten down the hatches: you're in for a real storm! Suggesting the 764 may not be perfect is an extreme opinion to hold on here!
Of all the idiocy I've seen on this website in the past 12 years, the child threatening to sue people for "defamation of character"(!) because they had a critical opinion of the 764 has to take the cake.
