Boeing B-777
The Boeing 777 is an American wide-body twin-engine jetliner, known as the world's largest twinjet, serving long-haul routes with exceptional range and efficiency.





Launched in 1995, the Boeing 777 revolutionized long-haul aviation by combining twin-engine efficiency with wide-body capacity, enabling airlines to operate point-to-point routes previously requiring four-engine aircraft. The 777's advanced systems, powerful engines, and passenger comfort have made it a cornerstone of international fleets, with variants including the 777-200, 777-300, and extended-range models serving the world's longest commercial routes.
