Okay so I'm a little late to the question but wanted to add my 2 cents! I mail cookies quite a bit, not that far, but they usually arrive pretty intact. I line the bottom of the container with fresh bread, or sometimes even buns, to help preserve moisture. This totally works. Then if you have room, add more to the top, especially for international travel. I put a layer of press and seal over the top before putting lid on. Fill the container as full as possible so there isn't a lot of room for them to bang into each other. My friend is always happy with her packages! ;) oh and I find chic chip holds up the best for me.
