You cannot compare a 380 burning 13,000kgs of fuel per hour and carrying 480 odd pax with a 777 burning 4,500kgs per hour carrying 400 pax. Those extra 80 pax are consuming 8,500kgs per HOUR every hour the jets are in the air. To put that another way, every flight QF takes to LAX they are selling an extra 80 odd seats but burning 120,000kgs of jet fuel extra to just about all their major competitors. London it's 240,000kgs. One way.
Close. The 777 Burns 8600kg per hour on long haul and carries 350 in a 3 class config.
