FILE - In this Feb. 22, 2012 fiile photo an aircraft flies over Frankfurt, central Germany. The global airline industry says, Wednesday, March 20, 2013, it sees a modest improvement in its financial outlook for 2013, expecting profits of US dollar 10.6 billion based on more passengers and cargo handled. The International Air Transport Association credits "a backdrop of improved optimism for global economic prospects" for raising expectations above its previous forecast of $8.4 billion in profits for this year. But the Geneva-based IATA cautioned that fuel prices are growing too. (AP Photo/Michael Probst, File) less
