Delta Air Lines on Tuesday morning reported a third quarter profit of $1.2 billion excluding special items, on revenue of $10.49 billion. This mark’s the first time in company history that quarterly profits have topped $1 billion. Overall, passenger revenues increased by $581 million. According to Delta’s Chief Financial Officer, Paul Jacobson, the record profitability was despite operational challenges that were faced due to summer weather. On the expense front, the airline’s costs grew by just over 1% for the quarter, besting the airline’s goal of 2% or less of growth per quarter. Since the start of 2013, Delta’s share price has doubled, and just last month, the airline was selected to rejoin the prestigious S&P 500.
