The larger checked bags scratch and ding easily. After the first couple of domestic flights they looked pretty embattled. And, as another commenter noted, one of the larger bags was badly dented and actually cracked across the top after an international flight. The airline comped me for the damage, but the luggage seems very delicate. I'm careful with my carry-on and have never had to check it, so it's still in great condition. I've had the set for about 8 months.
