The Seat amenity covers the physical seat type for every subfleet in every cabin of the aircraft, with corresponding score calculated in relation to all other possible seat types in that class cabin. For example, seat types in Economy cabins range from compact 27" pitched seats to roomier 36" seats. Each economy seat type is evaluated not only by pitch, but also by width.
In premium cabins, such as Business or First Class, premium features such as angled flat seat versus fully flat seat, direct aisle access and suite availability are fully evaluated.
