The terms "stewardess" and "flight attendant" describe the same basic job of tending to airplane passengers' needs and safety. "Stewardess," however, is an outdated term that has been replaced by "flight attendant" on all airlines. Whether fairly or unfairly, stewardesses became associated with the negative impression of being little more than models in the sky. The push in the 1960s and 1970s to remove the gender bias of job descriptions, combined with an increase in the number of men entering the field, made the term "flight attendant" the more appropriate and preferred term.
