To avoid this concern choose a suitcase made from polycarbonate ABS that stands up to the rigors of travel. The FERGE brand makes a TSA-lockable suitcase on wheels using polycarbonate ABS.

For maximum durability, the handle should have little to no wiggling or rattling as you pull the bag. Also, check for smooth movement as you pull it up and retract it. The suitcase's wheels should roll smoothly and stay in place. Gently jiggle the wheels with your hands to make sure they are firmly attached.
