Four engine jets including the Boeing 747 and the Airbus A380 put Qantas, Korean Air, and Asian Airlines at the bottom of the airline fuel efficiency ranking of transpacific flights. While Hainan Airlines and All Nippon Airways (ANA) are said to be the most fuel efficient with 36 passenger kilometers per liter of fuel. This claim was made by the International Council on Clean Transportation (ICCT) in the white paper in 2016. These low fuel uses are accomplished in very different ways. Hainan Airlines is an extremely advanced fleet with 81% of its available seats were on the Boeing 787 Dreamliner aircraft. While the All Nippon Airways (ANA) have a higher amount of burning fuel but carried more cargo.
Qantas was at the bottom of the ranking with only 22 passenger kilometers per liter of fuel due to it being the most fuel intensive with very low load capabilities with both cargo and passengers. The average passenger kilometers per liter of fuel within airlines is 31. Even lower than Qantas, was China Southern Airlines, China Eastern Airlines, Cathay Pacific, Philippine Airlines, and Singapore Airlines with 20 passenger kilometers per liter of fuel.
The International Council on Clean Transportation’s (ICCT’s) aviation program director, Dan Rutherford found that the fuel burn per passenger rises with the size and weight of the aircraft, which is why the 747s and A380s look so bad in this report. Qantas is looking to replace the 747s with the 787-9s that have the twin engine controls. The most recent twin-engine planes with a wider body meet the requirements for a transpacific flight but with much lower fuel burn.
