An airline operating long haul flights need to have full-flat seats in both First Class and Business Class. Economy class 5-Star seat pitch requirements have traditionally been set at 32-33 inches, but with newer slimline seats this is an area that Skytrax discuss with an individual airline to determine personal "seat space" that customers receive. The width and cabin layout (configuration) for Economy class seats is an area of discussion and change in the rating requirements for 5-Star airlines.
