A convertible travel case has a frame including an upright with a handle for grasping and a base with wheels for towing. A rigid case is mounted on the frame by a connector bracket having one portion pivotally connected with an upper part of the case and another portion slidably connected with the upright to permit the case to be shifted between a generally vertical storage position and a generally horizontal cart position. The frame and case have mating catch members at the bottom of the case. A releasable lock connects the connector bracket and the upright in a first raised position wherein the catch members are engaged to retain the case in the storage position, and a second lowered position wherein the catch members are disengaged and the lower end of the case is swung outwardly away from the frame with the connector bracket shifting downwardly along the upright to the cart position for supporting additional luggage on top of the case.
