Stewardesses had a lot of free time, and they chatted with young men in suits. That was back when most passengers were men with good jobs and no discount coupons. Jets ruined this. No, I have not forgotten airline food. Not only was what they served inedible, it was unidentifiable.
Price competition is the free market's way.
You paid far more for a ticket than today, but you got better food. At 23, I did not fly much in 1965. What I do remember was how cheap it was to fly intrastate in California, and how expensive it was to fly across a border.
