Casting For Airline Flight Attendants, China

Female flight attendants rapidly replaced male ones, and by 1936, they had all but taken over the role. They were selected not only for their knowledge but also for their characteristics. A 1936 New York Times article described the requirements:
"The girls who qualify for hostesses must be petite; weight 100 to 118 pounds; height 5 feet to 5 feet 4 inches; age 20 to 26 years. Add to that the rigid physical examination each must undergo four times every year, and you are assured of the bloom that goes with perfect health."
In the United States, they were required to be unmarried and were fired if they decided to wed. The requirement to be a registered nurse on an American airline was relaxed as more women were hired, and it disappeared almost entirely during World War II as many nurses enlisted in the armed forces. In 1962, St Bona of Pisa, a 12th-century pilgrim, was canonised by Pope John XXIII as patron saint of air hostesses.
