U.S. Airways, Delta and others are said to be studying the pros and cons of purchasing American Airlines and its parent company, AMR Corp., as the company goes through the bankruptcy process. American stands to get rid of billions in debt and to still be able to purchase a new fleet, but airline buyers will have to consider regulatory hurdles and union disputes. American has said it wants to stay independent. "Everybody has to be thinking about how to deal with AMR in two years. They will be the most efficient carrier with a new fleet. They're going to be very desirable," said aviation consultant Darryl Jenkins.
