A Fair comparison. I am asking a Fare comparisson .

The 777 was marketed as a replacement for airlines flying clapped out old 747 classics.
I for one could not see the comparison between the 2 when the 777-200 emerged as it was a (3 class config) 300 seater but the 777-300 is a 350 seat (3 class config) with more cubic cargo space than a 747.

Lets assume the aircraft will be based at the ass end of the earth (to quote a former prime minister) and many of your airlines cash earning routes are 6 - 8.5 hour flights to asia which would be well suited to the 777.

These routes for years have been serviced by 747 classic and 747-400 due to the fact that no new/efficient type aircraft were purchased in the 90s.

I am asking difference in fuel burn from a 777 to 747 as a 747 classic burns over 100K fuel to Japan and a 744 around 90K.

It would appear but I can not confirm that a 777-300 full pax and cargo over these distances would burn about 30K kgs less fuel

The Fair comparison is about commercial reality with the price of fuel souring thru the $70 US and more.

Can anyone help with these figures?
