The Airlines With The World's Widest Economy Seats In 2026

In 2026, several airlines are highlighted for offering the widest economy-class seats, with Japan Airlines leading due to a less common nine-abreast layout on its Boeing 777-300ER. The analysis notes that typical mainline economy seat widths are around 17 to 18 inches (43–45 cm), while some airlines reach nearly 19 inches on select aircraft. Japan Airlines configures the 777-300ER in 3-3-3 rather than the industry-standard 3-4-3, and its SKY SUITE seating is described as approximately 47 cm on the 777 and about 45 cm on the 767, translating to roughly 18.5 inches and 17.7 inches respectively. The airline also uses an eight-across layout on its 787-9, described as “more relaxed,” allowing additional width of about 5 cm, with seats estimated near 18.9 inches (48 cm). Other carriers cited for wider economy seats include Singapore Airlines and Cathay Pacific, with widths commonly up to about 19 inches and 47–48 cm on widebody aircraft.
