Boeing 777-300ER

Boeing launched the 777-300ER programme in 2000 as part of a wider next-generation twinjet initiative, with Air France placing the launch order. The 777-300ER made its first flight on 24 February 2003, and the FAA and EASA certified the model on 16 March 2004. The first delivery to Air France took place on 29 April 2004.

The 777-300ER combined the -300’s added capacity with the -200ER’s range, becoming the top-selling 777 variant in the late 2000s as airlines retired four-engine widebodies like the 747 and A340 in favour of more fuel-efficient twinjets. As of March 2016, the 777-300ER had 635 delivered and 800 orders, with Emirates operating the largest 777 fleet, a position it has continued to hold as the aircraft has become the backbone of several major long-haul carriers’ networks.

The Boeing 777-300ER retains the wide 777 fuselage cross-section, generally configured nine-abreast in economy (3-3-3), consistent with other 777 variants. Because each airline designs its own cabin, seating totals vary significantly. Typical seating capacity ranges from 314 to 451 passengers, depending on the operator and class mix. Business and first-class cabins also vary widely by carrier, from lie-flat suites to standard recliner seating.

The dimensions and weights below are for the standard 777-300ER production specification.

The Boeing 777-300ER is exclusively powered by the GE90-115B turbofan engine, the most powerful engine manufactured, and one of the defining features of the type.

In-seat amenities vary considerably by operator, ranging from basic seatback screens and USB power on older cabins to fully redesigned suites with Wi-Fi, large 4K entertainment screens, and lie-flat business seating on retrofitted or newer-delivery aircraft. As the aircraft has been in service for two decades, cabin standards differ significantly between an airline’s earliest and most recently refreshed 777-300ER airframes.

Boeing assembles the 777-300ER at its Everett facility in Washington, alongside the 777X.

The Boeing 777-300ER is one of the most widely operated widebody twinjets in service, flown by major long-haul carriers across every region.

The 777-300ER has an outstanding safety record for a widebody flying since 2004, with the variant itself having recorded no hull losses.

Notable safety events specific to the Boeing 777-300ER include:

The 777 family overall posts an accident rate of roughly 0.12 hull losses per million departures, among the best safety records of any widebody type, and the -300ER’s individual record reinforces its reputation as one of the most dependable long-haul aircraft ever built.
