I flew this past weekend in FC on a DL A319 that was empty (flight 2548). There were only 4 people in FC including myself and my girlfriend. We recently purchased a new puppy, so we took our two red DL blankets as well as 2 blue ones that were in Row 1 on unoccupied seats since we could use some "disposable" blankets. I assumed the blue ones were just the coach blankets, however when I opened them yesterday they had US Airways tags. Has anyone seen this before? I don't fly very often, but I thought it was strange.
