This may be comparing apples and oranges but for those in the know some rough figures would be help full..
A boeing 747-400 RR eng in a 3 class config 300 pax flying Sydney - Singapore
7h:45 min flight time
Fuel load approx 88,000 kgs
With this amount of fuel I assume there is also extra cargo other than pax bags but not sure how much cargo weight to assume.
A 777 in 3 class config same pax (cargo) etc
What would the fuel order be on same sector??
