Ageism is a factor in Mark Mitchell or anyone becoming a beginning flight attendant above the age of 30. Not Rippon over Minor.
I know someone who became a flight attendant in her 40s. There are no official upper age limits for flight attendants and it is illegal to discriminate against someone over age 40. That is not to say that there isn't unofficial age discrimination. But if
someone verbalized it to a candidate, the airline could get sued.
