Emiratesâ economy seats are 45.5cm wide on its A380 flights, 43cm on the Boeing 777-300ER aircraft that it uses for shorter services in and out of Australia. Qantas offers a standard economy width of 44.5cm right across its range of A380-800 aircraft and the various configurations of the 747-400 that it operates.
