Airline companies are required by law to provide flight attendants for the safety and security of passengers. The primary job of flight attendants is to keep passengers safe and to ensure that everyone follows security regulations. Flight attendants also try to make flights comfortable and enjoyable for passengers. Flight attendants work primarily in the cabin of an airplane. Although they enjoy much free time and many travel benefits, flight attendants’ work can be strenuous. Flight attendants stand during much of the flight and must remain pleasant, regardless of passenger demands or their own fatigue. Occasionally, flight attendants must deal with turbulence, which can make service more difficult and causes anxiety in some passengers. Applicants with a degree in hospitality, tourism, public relations, or communications may have an advantage over others. Most airlines also require 1 to 2 years of customer-service experience. Those who work on international flights may have to speak a foreign language fluently in addition to English.
