The Boeing 777-200LR Worldliner can hold 195,285 litres of jet fuel
The Boeing 777-200LR Worldliner is an ultra-long-range aircraft that can hold 195,285 litres of jet fuel. This is due to its additional fuel tanks in the rear cargo hold. The 777-200LR Worldliner was designed to be the longest-range aircraft in the world, connecting almost any two airports. It holds the world record for the longest non-stop flight by a commercial airliner, flying 21,601 kilometres (11,664 nautical miles) from Hong Kong to London Heathrow.
The 777-200LR Worldliner entered service in 2006, with Pakistan International Airlines (PIA) as its launch customer. The aircraft has a maximum range of 15,844 kilometres (8,555 nautical miles) and can carry 392 passengers in a two-class seating arrangement. To increase its fuel capacity and range, the 777-200LR features extended raked wingtips, a strengthened fuselage and wings, and a modified main landing gear.
The 777-200LR is powered by the GE90-115B turbofan engine, which is the world's most powerful jet engine. This engine provides a maximum thrust of 115,300 lbf (513 kN) and contributes to the aircraft's fuel efficiency. The 777-200LR's fuel efficiency is further enhanced by its wingtip extensions, which reduce takeoff field length and improve climb performance.
The Boeing 777 series has undergone continuous improvements to enhance its fuel capacity and efficiency. The 777-300ER variant, for example, received engine and aerodynamic improvements to reduce drag and weight. These changes allowed for a higher payload and increased takeoff weights at higher-altitude airports. The competition from Airbus' A350 XWB and the proposed 787 series also drove innovations in the 777 series to improve fuel efficiency and maintain its competitiveness in the market.

The 777-300ER variant received improvements to reduce drag and weight
The Boeing 777 is a wide-body airliner that has been in service since 2004. It is one of the most popular wide-body programmes in history, with the 777-300ER being the best-selling variant. The 777-300ER is a twin-engine, long-haul jet that can carry 392 passengers in a two-class seating arrangement. It is powered by the GE90-115B turbofan, the world's most powerful jet engine.
By the late 2000s, the 777-300ER variant received improvements to reduce drag and weight. These improvements were made in response to increased competition from Airbus' planned A350 XWB and the proposed 787 series, which offered better fuel efficiency. The 777-300ER received engine and aerodynamics improvement packages, including raked wingtips, which are a wingtip extension design that reduces drag and improves aerodynamic performance. These raked wingtips gave the aircraft a 2% boost in fuel efficiency, leading to significant savings in fuel costs and a reduction in CO2 emissions.
In 2010, the 777-300ER variant received a 5,000 lb (2,300 kg) maximum zero-fuel weight increase, allowing for a higher payload of 20-25 passengers. The GE90-115B1 engines were also enhanced, receiving a 1-2.5% increase in thrust for improved takeoff performance at higher-altitude airports. These changes ensured that the 777 remained the largest twin-engine jetliner in the world.
In March 2015, further details of the "improvement package" were released. The 777-300ER was set to shed 1,800 lb (820 kg) by replacing the fuselage crown with tie rods and composite integration panels, similar to those used on the 787. New flight control software was also introduced, eliminating the need for a tail skid by keeping the tail off the runway surface. Boeing also redesigned the inboard flap fairings to reduce drag and improve fuel efficiency. These changes allowed airlines to add 14 additional seats to the aircraft, increasing per-seat fuel efficiency by 5%.
The 777-300ER has continued to undergo modifications and remains a popular choice for long-haul operations. Its success has contributed to the 777 becoming the best-selling wide-body airliner, with over 2,300 orders placed by more than 60 customers as of June 2025.

The 777-200X/300X specifications were approved in March 1997
The 777-200X/300X specifications were approved by the Boeing board in March 1997. The 200X was designed to carry 298 passengers in three classes over 8,600 nautical miles (15,900 km; 9,900 mi). The 300X, on the other hand, was designed to carry 355 passengers in a tri-class layout over a distance of 6,600 nautical miles (12,200 km; 7,600 mi). The design freeze for these aircraft was planned for May 1998, with 200X certification scheduled for August 2000 and introduction in September of the same year. The 300X was to be introduced in January 2001.
The 777-200X/300X featured a 4.5 ft (1.37 m) wider wing that was to be strengthened, and an enlarged fuel capacity. The aircraft was to be powered by simple derivatives with similar fans. Various engine manufacturers proposed different options for the aircraft's engines. GE proposed a 102,000 lbf (454 kN) GE90-102B engine, while P&W offered its 98,000 lbf (436 kN) PW4098 engine. R-R proposed a 98,000 lbf (437 kN) Trent 8100 engine, and Rolls-Royce was also studying a Trent 8102 engine with over 100,000 lbf (445 kN) of thrust.
Boeing was also considering a semi-levered, articulated main gear to assist with the take-off rotation of the proposed -300X, which had a higher maximum take-off weight (MTOW) of 715,600 lb (324,600 kg). The 777-200X/300X specifications were part of the development of the 777 family of aircraft, which aimed to meet the increasing demands of airline planners for larger and more efficient aircraft.

The 777-200LR Worldliner set a world distance record for a commercial aircraft non-stop flight
The 777-200LR Worldliner is a long-range wide-body airliner developed and manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and the most-built wide-body airliner. The 777-200LR Worldliner set a world record for distance travelled non-stop by a commercial airplane when it flew 11,664 nautical miles (21,601 km) eastbound from Hong Kong to London Heathrow Airport in 22 hours and 42 minutes. This distance is farther than any previous commercial jetliner and exceeds a distance of more than halfway around the world.
The 777-200LR Worldliner replaced the previous distance record set by a 747-400 in 1989 that flew 9,200 nautical miles (17,039 km) non-stop from London to Sydney. It also exceeded the distance travelled by a 777-200ER (Extended Range) that flew 10,823 nautical miles (20,044 km) from Seattle to Kuala Lumpur in 1997, setting a speed and distance record. The 777-200LR is capable of connecting virtually any two cities around the globe and is the fifth 777 model.
The 777-200LR Worldliner features increased fuel capacity, allowing it to operate ultra-long-distance routes. The wings of the 777 series feature a supercritical airfoil design that is swept back at 31.6 degrees and optimized for cruising. The wings are also designed with increased thickness and a longer span, resulting in greater payload and range. The longer-range models can carry up to 47,890 US gallons (181,300 L) of fuel. This fuel capacity allows the 777-200LR to operate ultra-long-distance, trans-polar routes such as Toronto to Hong Kong.
The 777-200LR Worldliner's record-setting flight demonstrated its outstanding operating efficiency and reliability. It uses less fuel to fly farther, carry more passengers, and transport more revenue cargo than any other commercial jetliner. The 777-200LR is a testament to Boeing's leadership and innovation in the aerospace industry, offering unmatched capability and performance that has revolutionized long-haul air travel.
