Recently, I have always had my checked luggage inspected. The most embarrassing thing I had though was a few tampons. lol
I used to work for the airlines and the security people have seen it all, trust me. Besides think of it this way. They may SEE your little friends packed in your suitcase but they dont know whose suitcase it is. Youre a name, not a face.
When leaving from Chicago O'hare, you have to stack your suitcase up after you check in. Each bag is opened and checked but you dont have to stand around for that. Last time I flew back from chicago I had a huge Samsonite packed with American peanut butter, Rice a Roni and other foody things.
If your worried...chuck out your friends and get shiny new ones here!
