I remember my first solo trip well. I was flying from SEA- GEG to visit my grandparents. I had just turned 5 years old a few days before.
This was in August of 1976 and was in a “banana plane”. I don’t remember now the name of the airline, but they had yellow planes.
I was sitting in the window seat playing with my Charlie’s Angels cards (like baseball cards, only better!

). Sitting in the aisle seat was a guy who was telling me all about how he and his friends celebrated the “beer-centennial” (instead of the bicentennial). He thought my cards were cool also, so perhaps he had been celebrating recently also!
I still remember what I was wearing even. I don’t recall being worried or scared at all, and took more flights over the next 10 years or so with my sister or solo on the same route.
