I am on 4+ flights per week.  First gate check, it lost the zipper on the front small compartment.  Scuffs very easily.  Clothes are always more creased than with my Hartley, Atlantic, etc.  I like the way it fits into the the luggage compartment. Handle, wheels work well.  Finding local repair is a pain.. Will have to mail it back to replace the zipper.

Update from May 2013.  Lost the expansion zipper and one zipper tab on the closure zipper during commuter bag checks.  Random chance maybe, but still have all the zippers on the Hartley.  Atlantic loses the zipper tabs but not the whole zipper.  Sent for repair in June
