My mother's first airplane flight--and her first visit to another US state--was aboard a TWA Super Constellation bound for Kansas City in 1959. At the time, most airliners were piston-driven, but there were a few jets in service, and man, were they noisy.
Plus, Hollywood stars flying, lit cigarettes, getting on or off the Connie.
We knew a St. Paul restaurant owner who was also the ticket agent for TWA at Mpls/St. Paul Airport.
He did his ticket duty for two flights in the morning, ran back to downtown to open the Thai restaurant he and his wife owned, then back at 4pm for the two more flights by TWA.
He said the pay was pitiful but free flying was a benefit he couldn’t pass up.
When I enlisted in the Air Force in 1955 we flew TWA from Phoenix to San Francisco (Basic was at Parks AFB) with a several hour layover in LA. While in LA, the stewardess actually took us home to her apartment on the beach.
