BOEING 777X

Wing size matters when it comes to airplane’s fuel efficiency, no doubt the Boeing 777X makes the top list with its 235-foot wingspan. In the long run, this should reduce the cost per passenger seat and will make flying more available for people.

Price of Boeing 777X is $388.7 million which makes it one of the most expensive commercial airplanes in the world.
