An aircraft 1 comprises a walkway 11 moveable between a stowed position and a deployed position. The aircraft may be arranged such that the walkway, in the deployed position, defines a path, at least a portion of which extends from the fuselage at an angle, when viewed from above, of less than 90 degrees to the longitudinal axis of the aircraft. The walkway 11, in the stowed position, may be located at an angle, when viewed from above, of less than 80 degrees to the longitudinal axis of the aircraft. The opening 9 may be located in a region extending from 20% to 80% of the total cabin length. The walkway may be further moveable to a second deployed position. A longitudinal portion of the walkway 13, in the first deployed position, may define a stepped surface having a first step height, whereas that longitudinal portion of the walkway 13, in the second deployed position, may define either (a) a substantially even surface, or (b) a stepped surface having a second step height, the second step height being less than the first step height.
