Take a photo of you case with your cell phone. Take a photo of all paperwork and items period if you are going on safari. I could not find a certain paper I had in Zim but the photo on my phone worked fine instead. I was allowed to board and fly on to Namibia.
I always have a photo of me and my Tuffpak standing side by side...now they know what to look for and what it looks like.
Delta left all three of our gun cases in Atlanta July 4, 2012 after assuring us they were looking at the cases and they would go on that nights plane....wrong...then three days later they were sent to Livingstone, Zambia instead of Vic Falls, Zim. Fun trying to get guns across the bridge when you have no permit for Zambia and were not going there in the first place.
Shot game with borrowed 375. Then was treated most rude by 2 U.S. Custom agents in Atlanta on return.
