777300ER

The Boeing 777-300ER is the extended-range version of the 777-300, a wide-body twinjet airliner built by Boeing. It was developed to provide long-range, high-capacity service on major international routes and entered commercial service in 2004. The ER designation reflects its increased fuel capacity and range compared with the baseline 777-300.

The 777-300ER is powered by two General Electric GE90-115B engines and features a strengthened fuselage and landing gear, as well as increased fuel capacity and a wing with large, swept raked wingtips to improve efficiency. It shares the cockpit and many systems with other 777 variants, enabling common pilot type ratings. Typical layouts seat about 350 to 450 passengers depending on airline and configuration, with a range of roughly 7,370 nautical miles (13,650 kilometers).

Operational use: The 777-300ER has been widely adopted for long-haul routes by numerous airlines around the world. Major operators include Emirates, Qatar Airways, Cathay Pacific, Turkish Airlines, EVA Air, and Asiana, among others. It is commonly deployed on routes across Asia, Europe, and the Americas, including high-density transcontinental services.

Variants and production: The 777-300ER is part of Boeing's 777 family and remains in active service with multiple carriers. It competes with the Airbus A350-1000 in the long-range, high-capacity market and has helped sustain the 777 family’s prominence on long-haul routes.
