Well, I have one and I really don't like it very much. First time I used it the rear der bent (but that may have been my fault). Amazingly the fasteners used to hold the Thule advertising on the case are long and very sharp and rip the foam padding. You can't cut them off becuase the advertising is also part of the strapping system. I got mine with not only air travel in mind but also on top of the car travel. My recommendation, do not try to use it on top of a car. The design makes it impassible to waterproof without using a cover over the entire case. Addtionally, if you have a quiet car, when you put that thing on the roof, it will be quiet no more. Last, because it has NO aerodynamic design features, you can count on it trashing your gas mileage. Well, at least my frame did not crack!!
