Strange thing happened on our flight PHL-FLL yesterday. My wife and I were in the last row of F. She had used her blanket and left it in a pile on the seat at the end of the flight. My blanket was unused and was still in the plastic wrapper on my seat. As we exited the plane, a bulkhead Y passenger picks up her blanket and carries it off the plane in full view. As we walked through the concourse, he continued to carry the blanket draped over his arm. Just seemed very weird to me.
