The recession took a nasty toll on NetJets, one of Warren Buffett's holdings. While the company made a profit of $207 million in 2010, it lost $711 million the year before, Bloomberg reported.

NetJets owns a fleet of business aircraft and lets customers buy hours of flight time. With the economy picking up steam, Buffet apparently feels that demand for his aircrafts will also grow.

American Airlines had yet another difficult quarter, not unexpected in what has become an incredibly deep travel slump. The carrier's parent company, AMR Corp. (NYSE: AMR), reported a third quarter loss of $359 million, largely because there aren't as many business travelers taking to the skies. Corporate travel budgets in all industries are having an effect on all airlines, including AMR.

Revenue plunged 20.2% year-over-year for the third quarter for the nation's second airline. The loss comes after a $31 million gain last year. This quarter's losses would have been slightly better if write-downs for sold or grounded aircraft were excluded -- the loss would have been $265 million (93 cents a share) on revenue of $5.09 billion. With the write-downs, revenue clocked in at $5.13 billion. Cheaper fuel made the quarter a little easier for AMR to bear, as well, with this expense down 47% year-over-year.
