A long-range flagship of the twin-engine wide-body class, the Boeing 777-300ER pairs the stretched fuselage of the 777-300 with the range for intercontinental service. It seats around 365 passengers in two classes and up to 550 single-class, driven by two GE90-115BL turbofans — among the most powerful jet engines ever built — for a reach of about 13,650 km at 905 km/h. First flown in 2003, the aircraft is 73.9 metres long with a 64.8-metre wingspan and a maximum takeoff weight of 351,534 kg. Emirates operates more than 140 of the type, the largest fleet of any wide-body model, and the -300ER became a mainstay of premium long-haul networks worldwide.

Frequently Asked Questions
The Boeing 777-300ER typically seats 365 passengers in a standard three-class configuration. In a two-class layout, it can carry up to 396 passengers, and high-density single-class configurations can hold up to 550 passengers. The cabin is 5.87 m wide, one of the widest among twin-engine aircraft, allowing a spacious 3-3-3 arrangement in economy or 3-4-3 in high-density layouts.
The Boeing 777-300ER has a maximum range of approximately 13,650 km (7,370 nautical miles). This allows it to operate demanding long-haul routes such as Dubai to Los Angeles, Singapore to San Francisco, or Hong Kong to New York. The ER (Extended Range) designation indicates additional fuel capacity and the powerful GE90-115B engines, the most powerful turbofan engines ever to enter commercial service.
The Boeing 777-300ER is powered exclusively by General Electric GE90-115B engines, each producing up to 513 kN (115,300 lbf) of thrust. The GE90-115B holds the Guinness World Record for the most powerful commercial jet engine, having achieved 569 kN during testing. The engine's fan diameter of 3.25 m is so large that it is wider than the fuselage of a Boeing 737.
Emirates operates the world's largest 777-300ER fleet with over 130 aircraft, making it the cornerstone of the airline's long-haul network. Other major operators include Singapore Airlines, Cathay Pacific, Air France, Korean Air, and Qatar Airways. The 777-300ER has been the preferred long-haul workhorse for many premium carriers, with over 800 aircraft delivered since it entered service in 2004.
The 777-300ER is a larger and heavier aircraft than the A350-900, carrying about 65 more passengers in typical three-class layouts (365 vs 300). However, the A350-900 offers approximately 25% lower fuel burn per seat due to its composite airframe and newer-generation Trent XWB engines. The 777-300ER remains popular for its proven reliability and high-density routes, while the A350-900 is increasingly chosen for efficiency on medium-density long-haul sectors.
