Samsonite Supra 6 19" Carry On Rolling Luggage Carry On Sized - Luggage designed to fit in most airlines overhead compartments; may not conform to some airlines carry-on standards. SmoothRoller - Steel spring suspension allows the flexing arm of the SmoothRoller wheel housing to absorb the vibration and jolting that can occur due to inconsistencies in terrain. The shock suspension wheel housing with the SoftSpin wheels provides smooth transport. Push button handle - Locks when fully extended so you can push or pull your case. The handle also locks when fully recessed, greatly reducing the risk of damage when not in use. Top carry handle - Allows you to lift the case with ease and comfort, or carry it by hand when rolling isn't an option.
