Hi Linktrained,

If one takes Airbus average FH per a/c and figures (above) for its fleet, Mach .82 at cruise :

A340 = 5,000 FH/year => ~ 2400 (1000 NM)*380 kg = 912 tonnes saved per a/c.
-> 912*367 (a/c operational) => 334,704 tonnes of fuel.

A330 = 3,000 FH/year => ~ 1425 (1000 NM)*220 kg = 313 tonnes saved per a/c.
-> 313*791 (a/c operational) => 247,583 tonnes of fuel.

Total = 582,287 tonnes saved per year for the fleet.
Quite a few bucks then at today prices.
