The Gravis Jetway is a sturdy carry-on with skateboard wheels and customised liner. The inside has two zippered compartments and a separate large laundry bag. What makes the Jetway so great is that it has been specifically designed to fit perfectly in overhead bins and taxi trunks. This bag meets the carry on requirements for International flights as well as most Domestic including Qantas and JetStar. Some of the guys here at Rushfaster have these bags and love 'em.
