A method of positioning overhead storage bins within an aircraft interior, the method comprising the steps of: providing a first group of seats (1D, 1E, 1F) and a first group of overhead storage bins, positioning the first group of seats within the aircraft interior such that each of the first group of seats face forwardly, positioning the first group of overhead storage bins within the aircraft such that each of the first group of overhead storage bins is positioned above one of the first group of seats, wherein the first group of overhead storage bins each face forwardly; wherein the aircraft interior has a floor, an interior side wall and a ceiling, wherein the first group of seats are each secured to the floor, and wherein the first group of overhead storage bins are supported above the first group of seats by support structure, characterised in that said first group of overhead storage bins are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling; and providing a second group of seats (2D, 2E) and a second group of overhead storage bins, positioning the second group of seats within the aircraft interior such that each of the second group of seats face aft, and positioning the second group of overhead storage bins within the aircraft such that each of the second group of overhead storage bins is positioned above one of the second group of seats, wherein the second group of overhead storage bins each face aft; wherein the second group of seats are each secured to the floor, and wherein the second group of overhead storage bins are support above the second group of seats by support structure and are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling. providing a first group of seats (1D, 1E, 1F) and a first group of overhead storage bins, positioning the first group of seats within the aircraft interior such that each of the first group of seats face forwardly, positioning the first group of overhead storage bins within the aircraft such that each of the first group of overhead storage bins is positioned above one of the first group of seats, wherein the first group of overhead storage bins each face forwardly; wherein the aircraft interior has a floor, an interior side wall and a ceiling, wherein the first group of seats are each secured to the floor, and wherein the first group of overhead storage bins are supported above the first group of seats by support structure, characterised in that said first group of overhead storage bins are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling; and wherein the first group of overhead storage bins each face forwardly; wherein the aircraft interior has a floor, an interior side wall and a ceiling, wherein the first group of seats are each secured to the floor, and wherein the first group of overhead storage bins are supported above the first group of seats by support structure, characterised in that said first group of overhead storage bins are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling; and providing a second group of seats (2D, 2E) and a second group of overhead storage bins, positioning the second group of seats within the aircraft interior such that each of the second group of seats face aft, and positioning the second group of overhead storage bins within the aircraft such that each of the second group of overhead storage bins is positioned above one of the second group of seats, wherein the second group of overhead storage bins each face aft; wherein the second group of seats are each secured to the floor, and wherein the second group of overhead storage bins are support above the second group of seats by support structure and are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling. wherein the second group of overhead storage bins each face aft; wherein the second group of seats are each secured to the floor, and wherein the second group of overhead storage bins are support above the second group of seats by support structure and are secured to the floor by said support structure while being neither secured to the interior side wall nor to the ceiling.
