Why Do Airlines Still Use 3-3 Seating On Narrowbody Jets?

While some early Boeing 777s and Boeing 787s were configured nine and eight abreast, respectively, almost all airlines configure them ten and nine abreast, respectively, in economy class today. Some may also be doing this with new production standard Airbus A350s, which have an extra four inches in internal cabin width. Philippine Airlines has become the first flag carrier to configure economy ten abreast, instead of the standard nine abreast.
