Although flight crews—pilots and flight attendants—are the most visible occupations, the vast majority of the industry's employees work in ground occupations. Senior pilots for major airlines are among the highest paid workers in the Nation. A bachelor’s degree is increasingly required or preferred for most pilot and flight attendant jobs. Job prospects generally are better in regional and low-cost carriers than in major airlines, where competition for many jobs is keen; a unique benefit—free or reduced-fare transportation for airline employees and their immediate families—attracts many jobseekers.
Truck drivers and driver/sales workers hold 45 percent of all jobs in the industry. Job opportunities are expected to be favorable for truck drivers and diesel service technicians. Growth in the industry reflects ups and downs in the national economy. Many jobs require only a high school education. [ Source - Career Guide to Industries ]
