Japan Airlines ordered fuel-saving Blended Winglet Systems for 6 of its Boeing 767-300ER aircraft in early 2013.
The supplier of the blended winglet systems, Aviation Partners Boeing (APB), claims that the airline will achieve fuel savings of 4-5 percent with the use of this system.
The wingtip devices, similar to the sharklets offered by Airbus on its aircraft, have become very popular with the airlines due to the fuel-savings they offer.
The upward wingtip extensions improve the aerodynamics of the aircraft, thereby reducing fuel consumption and carbon emissions.
Japan Airlines has already installed blended winglets on many of its Boeing 737 Next Generation aircraft.
