Good luggage is an investment. It'll set you back, but the alternative is to have all of your possessions threatening to bust out of cheap zippered suitcase sides or holey pockets. Not a pretty sight after a long flight. The Pininfarina Hardside Luggage ($295-395) by Bric will take a few beatings and then some. It's made of polycarbonate and metal (think Han Solo strength), so your stuff will stay safely tucked inside, even when rough hands or rough air toss it all over the cargo hold.
