Yep thats my worry to the point we are thinking about buying a cheapie stroller or something just for the holiday, i would hate to think what my P&T vibe might look like after the flight. We were at Melbourne airport near the windows where you can see them with the conveyor belt loading bags etc and one handlers was throwing luggage up to high on the conveyor that you could just see what was going to happen and the suitcase kept falling off and he kept doing the same thing in plain view of passengers. Even most suitcase aren't cheap and you don't need to be having to replace them everytime you travel.
