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

Most mainline economy class seats have a seat width of around 17 to 18 inches (43-45 cm), with many US-based carrier widebody seats being closer to 17 inches. A few airlines go over 18 inches up to as much as 19 inches (48.26 cm) on select aircraft types. At the other end of the spectrum, airlines like the low-cost airline French Bee have seats just 16.7 inches wide.
