Question: what is the fuel consumption of a boeing 777?
Answer: 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.
