Shorter distances such as the Atlantic, we can load up more in cargo, for a mgtow of 870,000 lbs. We usually bulk out first. In cruise depending on weight and altitude, I've seen FF from 4.0 to 6.0 per engine.
Some one told me a 777 can carry 90% of what a 744 can do. Don't know if they were referring to bulk or density.
