By introducing the super-efficient and long-range 787 family, the airline group will be able to fly farther and reduce fuel costs and emissions by more than 20 percent compared to previous-generation jets, the release added.

The 787 Dreamliner is a family of long-range and fuel-efficient commercial airplanes that entered service in 2011. It can fly 242 passengers, in a typical two-class configuration, up to 7,355 nautical miles (13,620 km).
In 2013, two years after the plane was introduced, electrical fires on two Japanese owned planes prompted Federal Aviation Administration (FAA) to ground the planes for safety checks and design modifications.
With both the Dreamliner and 737 Max, problems were linked to the introduction of new technology.
Lithium-ion batteries for the Dreamliner electrical systems caused two fires, and preliminary reports on the 737 Max blame glitches in the plane's computerized auto-pilot. Two 737 Max crashes, in Indonesia and Ethiopia, killed a combined total of 346 passengers and crew.
