The Boeing 777-200(ER) is a wide-body aircraft and an extended range variant of the 777-200. The 777-200(ER) is identical in shape and size to the 777-200 except that it is equipped with additional fuel tanks to allow the aircraft to either fly farther or with more passengers & cargo without range penalties. The 777-200(ER) gives airlines the ability to improve their long-haul fleet offering by allowing them to fly to further destinations with the same capacity of a 777-200. While the 777-200(ER) replaced the older 777-200, it too is starting to be replaced with more modern long-range airliners and is no longer in production. This aircraft flies long haul routes with medium to heavy demand.
