"In 1965, female flight attendants had to be between the ages of 21 and 27 and they could only work with the airline for a maximum of 10 years, revealed Wendy Barlow, who was born in 1942. They also had to be single, although some stewardesses would keep their marriages secret in order to hold onto their jobs. It was acceptable to be widowed or divorced, however. They weren’t allowed to have children and they certainly weren’t allowed to be pregnant.
Physical appearances were crucial, too. They needed to have a "neatly proportioned figure" and "pleasing appearance,” Barlow told British Airways when they invited her, and others from the class of '65, to share their memories of flying during the "golden age" of air travel, fifty years on in 2015.
They were not allowed to weigh more than 140 pounds. A New York Times classified ad for stewardesses at Eastern Airlines listed the following requirements in 1966: "A high school graduate, single (widows and divorcees with no children considered), 20 years of age (girls 19 1/2 may apply for future consideration). 5'2" but no more than 5'9", weight 105 to 135 in proportion to height." Further pre-requisites included a good smile (no gums, all teeth) and being able to hold a conversation. The female flight attendants had to stay on top of their appearance on the job, too. Wendy explained that during training at BOAC they had a visit from Elizabeth Arden who taught them how to apply makeup.
Nail varnish wasn’t allowed to chipped either, or they’d be in trouble. In the 1970’s the strict rules started to change, with the organisation Stewardesses For Women’s Rights (SFWR) forcing airlines to relax the regulations. "
