I'd take em with ya. Have shipped a few times and the case looks the worse for wear afterwards makes you wonder how high the dropped the case from with some of the dings and dents, plus the cost.

Have travelled with mine on United all over the world with a hard case and the wear and tear is definitly better when they travel with you.
