Japan Airlines has launched GEnx-powered Boeing 787 Dreamliner flights between Boston Logan and Tokyo, Narita.

JAL’s 787 Dreamliner is currently fitted with 42 seats in business, featuring the Executive Class JAL Shell Flat Neo seats that are five cm wider (than the seats now fitted on JAL’s Boeing 777s) in a 2-2-2 configuration, and 144 in Economy Class with two cm wider space than current seats and arranged in a 2-4-2 configuration.

Some highlights of the revolutionary aircraft include larger windows with electronically dimmable shades, as well as higher ceilings, lower cabin pressure and better humidity for a noticeably more comfortable in-flight experience.

Utilising the LED lights in the Dreamliner, JAL created an original cabin lighting design to enhance the ambience onboard with a sense of the four seasons in Japan, such as pink hues of cherry blossoms in spring, or sky blue in the summer months of July and August.

The lighting also adapts at various timings during the flight, to make the environment more conducive during meal service and for resting or waking up.

“By deploying the 787 Dreamliner on long-haul routes to markets that can garner substantial travel demand such as Boston, JAL is making best use of the aircraft’s long-range capability, appropriate capacity, and its economic performance,” said JAL president Yoshiharu Ueki.

“We are very happy to have such strong support from the Boston community, Massport, Boeing, and joint business partner American Airlines, to establish this direct link between Boston and Tokyo never-before available.”

JAL has on order a total of 45 Boeing 787 Dreamliners.
