For more than 20 years, the Boeing 777-300ER has played a significant role in long-haul aviation. As an extended-range version of the original 777-300, it has become a key part of international airline fleets, connecting major cities with a combination of range and capacity. While newer aircraft like the Airbus A350 have entered the market, the 777-300ER remains a mainstay for many airlines due to its established engineering, operational flexibility, and passenger appeal.
The Boeing 777-300ER is known for its spacious cabin, which offers a wider interior compared to the Airbus A350. Airlines can choose between a 9-abreast or 10-abreast seating layout, allowing for either increased comfort or higher capacity. The aircraft also features larger windows—about 12% bigger than those on the A350—high ceilings, and overhead bins designed for accessibility and storage. These design choices contribute to a more comfortable experience for passengers across all classes.
In terms of capacity, the 777-300ER typically seats between 365 and 396 passengers, while the A350-900 usually accommodates 300 to 350. This difference, though it may seem small, can result in significant additional revenue for airlines over time. The 777-300ER also has a higher cargo capacity, with a design that allows for substantial freight volumes without reducing passenger load. This is particularly important on international routes where cargo contributes to overall profitability.
