ATLANTA -- Delta Air Lines is hiring a brand new batch of flight attendants to begin training in 2016.

The Atlanta-based airline is looking for flight attendants who speak Danish, Dutch, French, Italian, Portuguese or Spanish in addition to English. Positions that do not require bilingual skills are also available.

ATLANTA -- Delta Air Lines reported $1 billion in adjusted net income, or $1.27 per share, during the second quarter, the company announced Wednesday.

That profit, based on lower-than-expected fuel prices and other operational savings, was 22% higher than the same months of April, May and June in 2014. The company returned $1 billion to shareholders through dividends and share buybacks.

"Delta's record results have allowed the company to invest in its employees through higher wage rates and profit sharing; improve the experience for our customers through new aircraft and innovative partnerships with global carriers; and uniquely deliver value for our shareholders by accelerating our capital returns while also paying down debt," CEO Richard Anderson said in a statement.

ATLANTA -- The U.S. Department of Justice is investigating whether airlines, including Atlanta-based Delta Air Lines, are colluding to grow at a slower pace in an effort to keep fares high.

According to the investigation, major airlines are working together to limit seating and eliminate unprofitable flights. This allows them to increase ticket prices and extra charges. Airfares have risen 13 percent since 2009.

The Department of Justice sent letters to four airlines, asking for copies of all communications between them. Investigators also want to see conversations among the airlines, Wall Street analysts and major shareholders about plans for passenger capacity.

After a series of mergers starting in 2008, four airlines -- American, Delta, Southwest and United -- now control more than 80 percent of seats in the U.S.
