I travel regularly with my shotguns (as a matter of fact, just got back from South Dakota), and it is really a simple totally no hassle process. In fact I have never had any problems (missing or delayed), gun cases seem to get special treatment in baggage handling. Details are available on DL website I think (looks like they were posted), but basically, you need a good quality (to survive the abuse) LOCKABLE (must be locked) gun case. I have used a John Hall case (which are unfortunately no longer available) for about 15 years and it is just now about dead and will be replaced with an Americase. At check in, tell the agent you need a firearms declaration card, which you sign (declaring your gun unloaded) and put INSIDE your guncase. It is very rare to have the agent inspect the guns (in my experience less than 1 in 10 times), most wouldn't know what they are looking for anyway. No ammunition with the guns. That's it. If the security screening is where you can see it, it is a good idea to wait until they clear the gun case in case they need to open it, otherwise they will instruct you on what to do with the locks for screening. Hope that helps.
