Planned to replace ageing 747-100s and -200s, the 777-300 lengthened Boeing's twinjet into one of the longest airliners flying, first taking off in 1997. Two General Electric GE90-94B engines seat 368 in typical cabins and up to 550 when densely fitted, over roughly 11,135 km at about 905 km/h. The jet runs 73.86 metres long on a 60.93-metre wing, climbs to a 13,100-metre ceiling, and grosses up to 299,370 kg. Its sheer capacity suited crowded trunk routes where airport slots, rather than range, set the ceiling on growth. Later extended-range models eventually supplanted it, and it is no longer built. Controllers file it as B773.

Frequently Asked Questions
The Boeing 777-300 typically seats 365 passengers in a three-class configuration. In a single-class high-density layout, it can carry up to 550 passengers, making it one of the highest-capacity twin-engine aircraft. At 73.9 m, the 777-300 is one of the longest commercial aircraft ever built, designed as a replacement for the Boeing 747-100 and 747-200.
The standard Boeing 777-300 has a maximum range of approximately 11,135 km (6,015 nautical miles). This is sufficient for intra-Asian, trans-Pacific to Hawaii, or European routes from the Middle East. The range is limited compared to the 777-300ER variant (13,649 km) because the standard 777-300 uses older engines and has a lower maximum takeoff weight.
The 777-300ER offers significantly greater range (13,649 km vs 11,135 km) and higher maximum takeoff weight thanks to more powerful GE90-115B engines and additional fuel capacity. The 777-300ER became vastly more successful commercially, with over 800 deliveries compared to just 60 standard 777-300 aircraft. The 777-300ER also features raked wingtips, which improve fuel efficiency.
The 777-300 is identifiable by its extremely long fuselage with a tail skid to protect against tail strikes during rotation. Unlike the 777-300ER, the standard 777-300 has conventional rounded wingtips rather than raked wingtips. The main landing gear has six-wheel bogies like all 777 variants. Its engines may be Pratt & Whitney PW4098, Rolls-Royce Trent 892, or GE90-94B, depending on the operator.
Only a small number of airlines continue to operate the standard 777-300, as most have transitioned to the 777-300ER. Cathay Pacific, Singapore Airlines, and Emirates have operated 777-300s on high-density regional routes. All Nippon Airways and Japan Airlines also used the type on domestic trunk routes. With only 60 aircraft built, the standard 777-300 is one of the rarest 777 variants, and most remaining examples are nearing retirement.
