Hey, before there was mileage, you had to have something airline-related to call an addiction.
I thought of another childhood adventure. My father and I would fly between Philadelphia and Miami every Christmas to visit family. We always flew Eastern or Delta nonstop. When I was about 14, I convinced him to fly TWA from PHL to PIT, connect and continue on TWA to MIA. Why? Because I wanted to fly on a 707 (on the short PHL-PIT route!) one last time since TWA was retiring the 707.
