Flight attendants or cabin crew (also known as stewards/stewardesses, air hosts/hostesses, cabin attendants) are members of an aircrew employed by airlines primarily to ensure the safety and comfort of passengers aboard commercial flights, on select business jet aircraft, and on some military aircraft.

The primary role of a flight attendant is to ensure passenger safety. In addition to this, flight attendants are often tasked with customer service duties such as serving meals and drinks, as a secondary responsibility.

The number of flight attendants required on flights are mandated by international safety regulations. For planes with up to 19 passenger seats, no flight attendant is needed. For larger planes, one flight attendant per 50 passenger seats is needed.

The majority of flight attendants for most airlines are female, though a substantial number of males have entered the industry since the 1970s.
