The International Air Transport Association said Thursday it forecasts a profit of $19.7 billion -- well above the $12.9 billion expected this year and the $7.4 billion made in 2012.
But the Geneva-based group, which represents 240 airlines, or 84 percent of total air traffic, noted margins are dropping. Next year's profit would come from projected revenues of $743 billion. By contrast, 2010's $19.2 billion profit was made on revenues of just $579 billion.
Tony Tyler, director-general and CEO of IATA, said that the profit would amount to a little less than $6 a passenger.
"To put that into perspective, the McDonald's down the road here in Geneva will make about the same amount of profit by selling four Happy Meals at a cost in Geneva of $30," Tyler told reporters.
That kind of margin, at 20 percent, is well out of reach for airlines, he said.
"It begs the question of whether $6 per passenger is a reasonable reward for airlines if you consider the technology, skills and capital that is invested," he said.
Passenger traffic has been expanding by about 5-6 percent and jet fuel prices remain high, but below their 2012 peak, Tyler said.
He attributed that to "a slight fall in the high price of oil" and the efficiencies of mergers and joint ventures, along with more success at cutting costs. More airlines, for example, are charging passengers separately for food, baggage and other items.
North American airlines are expected to make the biggest profit next year -- $8.3 billion, up from $5.8 billion this year -- but see only a modest increase in demand for flight travel.
Carriers in Europe, where the economy has fared worse than other developed markets, are expected to have smaller profits -- $3.2 billion in 2014 from $1.7 billion this year. But they are due to enjoy a sharper recovery in passenger traffic as the recession ends in some countries.
The highest growth in demand is forecast in emerging markets in Asia, the Pacific region, the Middle East, Latin America and Africa.
Asian airlines should see profits hit $4.1 billion next year, ending a three-year drop in earnings, while the Middle Eastern ones should see steady growth -- to $2.4 billion from $1.6 billion.
