| Revenues and Costs While airlines  earn revenue from transporting cargo, selling  frequent flier miles to other companies and up-selling inflight services, the largest proportion of revenue is  derived from regular and  business passengers. Major airline costs   include:  
                  Labor – According to the Air  Transportation Association (ATA), labor is an airline's No.1 cost. Airlines must pay pilots, flight attendants, baggage handlers,  dispatchers, customer service  representatives and others to operate. Fuel cost – Fuel ranks second in an  airline's total costs. Fuel efficiency varies  widely among different carriers. Short haul airlines  typically enjoy lower fuel efficiency because take-offs and landings consume large amounts of jet  fuel.
 
                    The airline industry is capital-intensive which translates into high  fixed costs, i.e.  about two-thirds of  the cost structure of the airline industry are fixed costs. Coupled with a  high dependence on the economic cycle and fuel prices, the airline industry is  considered to be unstable. Many airlines fail to survive when negative  externalities strike. Positive externalities often result in over-optimistic future  projections. Market conditions greatly affect both the  demand  and the ticket prices for tickets.Financing  costs – As aircraft are expensive, leasing or debt financing is necessary. The  airline industry is sensitive to changes in interest rates.      |
