Japan Airlines operates Boeing 777-300ER aircraft at 9-abreast economy seating rather than the standard 10-abreast layout, offering 18.5 inch wide seats.[^1] The carrier is the only operator running Boeing 787 Dreamliners in an 8-abreast economy configuration, with 18.9 inch seats.[^2]

Singapore Airlines, Cathay Pacific and Asiana Airlines also operate widebody aircraft with economy seats between 18.5 and 19 inches wide.[^3] Korean Air reversed a planned reconfiguration of its 777 fleet to 10-abreast seating following public backlash.[^4]

Aircraft flying the Lisbon-Orlando route are laid out with 34 Business Class, 12 Economy Prime and 240 Economy Class seats.[^5]

Alaska Airlines will fit seatback screens only on the top two premium cabins of its Boeing 737 MAX 10 fleet, covering approximately 15% of total seats on the type.[^6] The FAA certified the 737 MAX 10 on 20 October 2026.[^7] Alaska expects first deliveries of the aircraft in the second quarter of 2027, with premium configured units entering transcontinental service in 2028.[^8]
