A towing arrangement includes a pivotal handle which allows a user to position the handle more comfortably that would otherwise be possible with a conventional towing arrangement. The relative motion of the handle can also increase the maneuverability of a piece of luggage by eliminating the need for a person to reposition his or her hand on the handle when attempting to redirect the piece of luggage.
