The Boeing 777, a long-haul favorite among passengers, has seen changes in its seating configurations over the years. Originally designed with a wide cabin to accommodate 9-abreast seating, many airlines have transitioned to a denser 10-abreast layout. This shift aims to improve profitability by reducing cost per seat mile (CASM), though it may compromise passenger comfort.
"A 1992 Industrial Design Excellence award was presented for its 777 passenger cabin. This [was] the first time the Industrial Designers Society of America honored an airplane interior," Boeing noted about the aircraft's initial design accolades.
While major carriers like American Airlines, United Airlines, KLM, and Air France have adopted the 10-abreast configuration, some airlines continue to offer the original 9-abreast seating. According to Sam Chui's article, airlines such as Air China, ANA, EVA Air, Japan Airlines, Korean Air, Singapore Airlines, and Thai Airways maintain this more spacious arrangement.
