Idiots are using outdated numbers when trying to compare Jumbo Fuel burn via the 2 is better than 4 logic. Plenty of these twerps out there, mostly Airbus fags. Take a look at the numbers for the A350, then read the entry for the 747. ;)
Here is some stuff from Quora
An Airbus A330-200E burns ~5.2t of fuel an hour at 870km/h @ 30,000 ft. Airbus A330-300E burns ~5.46t of fuel an hour in comparison. The A330-800neo will burn some ~4.8t of fuel an hour while the A330-900neo will burn ~5.2t of fuel per hour. That leads to an operating cost of about $6,862.05 to $7,188.00 per hour. Per seat that's $27.12 per hour for the -800neo and $23.96 per hour for the -900neo.
An Airbus A350 burns ~5.49t of fuel an hour at 900 km/h, and ~5.56t of fuel per hour at 910 km/h. That's equal to about $7,841.00 per hour. Per seat that's about $24.89 per hour.
A Boeing 777, specifically the 777-200LR burns ~6.8t of fuel per hour while the 777-300ER burns ~7.5t of fuel per hour while cruising at 892 km/h @ 30,000 ft. A 2016 upgrade package increases fuel efficiency by 2%. This decreases fuel consumption on the -200LR to ~6.66t per hour and the -300ER to ~7.35t per hour. That's 8,297 L/hr (-200LR) and 9,206 L/hr (-300ER).
Boeing states that under regular conditions, the 777-200LR should cost around $9,750.00/hour to operate, with the 777-300ER at a cost of $10,250.00/hour to operate. In a two class configuration this is around $32.39/hour per seat for the -200LR and $27.12/hour per seat for the -300ER. About 60% of that is the cost fuel of fuel alone.
The Boeing 747-8I/F burns ~8.83t per hour or about 10,114 L/hr at 929 km/hr @ 32,000 ft. That's a fuel cost of about $7,150.00 per hour or approximately $15.31 per seat per hour. Boeing states the total operating cost is closer to $13,450.00 per hour or about $28.80 per seat per hour.
