Boeing 777-300ER: Specifications, Range and History

The Boeing 777-300ER is the extended-range version of the stretched 777-300 and the best-selling 777 of all. It combines the 73.9 m fuselage of the -300 with raked wingtips, a higher takeoff weight and the GE90-115B, the most powerful jet engine in airline service.

Boeing launched the second-generation 777 programme on 29 February 2000 with Air France as first customer. The 777-300ER first flew on 24 February 2003 and was delivered to Air France on 29 April 2004. Boeing has delivered 833.
