Hi,  if you do your homework properly, expect to land the 777 in a straigh in approach with 20-21,000 lbs of residual fuel at the end of a flight.
This is 106 minutes of reserve plus an alternate within 75 nm

Under the same condition the 757 will land with 9000 lbs of fuel.
I dont know why but the 57 carries 19 minutes more in reserve

Please dont come home with the FMC message  "Insufficient fuel. "
meaning FMC predict 2000 lbs or less at destination   :(  :'(

Happy flying   ;D
