If you think that flying Delta with your guns will be an improvement over Emirates, you are in for a very unpleasant surprise. Delta lost my rifle flying to Joberg--left it in Dallas-- and couldn't find it for three days. I finally picked it up in Port Elizabeth after it was located by Air 2000 and directed to my location. I was filming a dvd and had to use that particular rifle, a Sharps. It cost me four days of a ten day safari.
