An aircraft wing (102 fig 1) includes a closed surface wing tip device (104 fig 1) which includes an element or actuator 330 within the wing tip for deforming/morphing the shape of the wing tip between geometrical configurations having different aerodynamic properties, for example including one with better overall fuel efficiency for a shorter journey and one with overall fuel efficiency better suited for a longer journey. The device 400 includes a lower winglet 406 with an essentially planar portion 410 spaced apart from the main body of the wing by a blended transition region which is shaped such that the curvature of the local dihedral increases in the outboard direction. The device 400 includes an upper aerofoil structure 414 which with the winglet 406 essentially forms the closed surface.
