At the time of its launch in 1998, the 777-300 was the longest commercial jetliner in aviation history. The 777-300 is a high-capacity, stretched version of Boeing's 777-200 wide-body twinjet. It is 33 feet (10 meters) longer than the initial 777-200 model, for a total length of 242 feet, 4 inches (73.9 meters). As a result, the 777-300 carries 20 percent more passengers than the -200, for a total of 368 to 550, depending on the configuration.
