Delta Air Lines beats Q2 profit forecasts, shares rise on outlook confirmation

The figures caused Delta Air Lines' stock to rise in futures trading on Wall Street ahead of Friday's stock market opening there.

Strong demand for business and international travel in higher price categories helped maintain margins despite significantly more expensive jet fuel.

"We have to continue to make sure we cover our costs, and one of the biggest costs is fuel, which has gone up by 50 percent," says Ed Bastian, CEO of Delta Air Lines.

Earnings of $1.56 per share in the quarter compare with an average forecast among analysts of $1.51 per share.

Revenue rose 14 percent, while the company's flight capacity increased by only 1 percent.
