Even at the low end, air travel was impressive. PSA was a low-cost airline. SJC to LAX, every hour, for about $14, with a 59 minute flight time. The process was very simple. Drive up to terminal. Park. Walk up to cash register. Pay. The register receipt was the boarding pass. A 727 pulls up and lowers the rear stairs. People get off. After a few minutes, the person who ran the cash register leads everyone waiting out to the plane, and they climb the stairs. Stairs retract, and plane takes off.
