I have an Americase double sided take down - it is built like a tank and if somehow you can damage it the customer service is great. But it also weighs like a tank, it is my choice when travelling by vehicle. I have no doubt the case would survive even if the truck didn't.
My last airline trip with a firearm, I borrowed a friend's TuffPak -

it was a breeze get through the airport, it does not scream gun, several people asked about golf and i saw it handled by baggagemen a couple times and due to its conformation they had to stack it carefully. ( as opposed to one friend who watch his aluminum case miss landing on the baggage cart when tossed from the plane). and everything arrived in perfect shape.
