The Boeing 777-300-ER (Extended Range) is an enhanced version of the 777-300, designed to offer even greater range, improved fuel efficiency, and a higher maximum takeoff weight (MTOW). Introduced in 2004, the 777-300-ER is equipped with more powerful engines and advanced aerodynamics, making it a preferred choice for airlines needing to operate long-haul flights with high passenger demand and additional cargo capacity.

This aircraft is capable of flying longer distances without compromising on passenger comfort or cargo capacity. It is widely used for transpacific and transatlantic flights, as well as other long-range international routes, where airlines need to maximize the number of passengers and cargo they can carry efficiently.
