I wish they would just give you a weight allowance ie 23kg but allow two cases within that. We have just got back and flew PE so allowed two cases at 23KG each. I took two cases but each one was only about 14kg - it was so much easier to carry these but a 23kg case is about as heavy as I can manage and I always worry about hurting my back etc. I know they have wheels but you still need to lift them off the belt etc.
