The earliest flight I remember was Los Angeles to Dallas, in 1946 so I would have been 5 years old. I don't remember the airline or the craft, but it was a taildragger (DC-3? -6?) and the stewardesses wore blue uniforms, so it might have been Pan-Am. I also got to "help" the stewardesses but then the flight turned bumpy and they made me sit down; just as well because many of the passengers became airsick. I thought it was great! Of course, in those days I used to love roller coasters, too. Funny thing is, I don't remember the flight back.
