Largest Airline Companies by Revenue, 2013 (in $millions)
Although the size of an airline can be measured by the
amount of passengers or cargo it carries, such figures do not
well reflect the passenger and cargo specialization of some
airlines. Under such circumstances, the revenue can be used. North American airlines tend to be among the most
profitable since they are operating in an oligopolistic market
with extensive demand. Still, European and Asian (Chinese)
airlines have substantially increased their revenue due to the
growth of their respective markets.
