My Columbia 4-Ball has been all over the place and no problems. It has gone on flights with United - LAx to Chicago Ohare to Greensboro and back. It has also been on Southwest from LAX to San Jose, Oakland, Indianapolis, St Louis, Reno 2x, Las Vegas, and back from all locations. None of my equipment has been damaged and the bag is still in great shape.
