Yep, everything worked out just fine. I was actually carrying up some frags with me to someone who purchased them. I was worried at first until I saw the box being loaded into the plane as I sat there at the window seat. My main concern was how Southwest and TSA would treat such a package. I didn't tell SWA that it was live animals and apparently TSA didn't need to open the box. I did leave out the heat pack though b/c it would look suspcious in the X-ray.
