No, those terms were discarded about thirty years ago.
They are ‘Flight Attendants’ now. No need for separate terms for males and females or ‘other’............................
I have always wondered why stewards and stewardesses accepted being called "flight attendants." Steward/stewardess implies trust, responsibility, care, and being in charge. "Flight attendant" does not carry these connotations and implies that someone is merely present or on hand, like a "gas station attendant."
