American Airlines reported a $1.34 billion profit for the second quarter, boosted by strong ticket sales and a huge drop in the price of jet fuel, and the airline raised its profit expectations for the year. International travel in particular is picking up, and that is helping American, United Airlines and Delta Air Lines. Thanks to lower fuel prices, the carrier's spending at the pump plunged 32%, saving the American about $1.3 billion compared with a year earlier.
