My dad worked for Delta (well, it was Western Airlines when he started) for 35 years. My family, of course, flew non-rev, and as was the case back in those pre-deregulation, pre-frequent flyer miles era, we often got to sit in First Class. I remember that even as a 10 year old, I had to wear kid slacks and a kid sports jacket. In fact, when a friend from jr. high told me he was flying in First (revenue), I warned him that he had to wear a jacket and tie or he wouldn't be let on! I simply didn't know any better.
