Once we flew into San Fran and did not so much as collect our case as was given by the handlers a couple of plastic sacks as the case had disintegrated after we checked it in at Mexico City. Fair play to Aeromexico they 'gave ' us a lovely 'Hercules ' hard shell as it was their fault..4 wheel steering and we have used it the last 8 years. There is no way the loaders can harm this beauty ..Easily swallows 22Kg ..and more if we can get away with it 😁
