I used to carry it under my arm just in case I was flying with one of the hat loving management in which case I would put it on, always felt like a real prat wearing it however. When I got my command I left it at home from day one and never bought it in again. The company recently made them optional, a few still wear them but most had already given up before the memo. I suspect if the hat that was issued had been a bit better more would have worn them but it was the most cheap and crappy cap you could imagine and looked pretty awful on most people.
