corporate-wage-slave you have evoked some memories. When I was a student nurse, I would sometimes help out the Mother of a friend who had a travel agency. Those tickets had to run over an airline template and all of them and the ticket stock had to go in the safe. God help you if you lost or had any stolen. I learned to write tickets and your handwriting had to be good and clear. As I recall you called the airline, booked, and got a locator. Fares were extremely complex when it was not a point to point. You could ring 20 different airlines and get 20 different fares when the routing was complicated. Back then we had loads of passengers from Germany and Switzerland coming to buy tickets as they saved hundreds of pounds.
I remember when the airlines went paperless. That killed the travel agents to a large extent. This E ticket is, to my mind an anachronism. The move to paperless was very radical and very advanced. The tons of paper that existed just stopped.
Now I have truly shown my age. I’ll go back to Jurassic Park as it will be feeding time soon.
