JetBlue Airways jetted past fourth-quarter earnings expectations, but a forecast of high costs and a general sell-off in U.S. stocks kept the airline's shares grounded on Thursday. Forest Hills, N.Y.-based JetBlue Airways said it earned $11 million, or 4 cents per share, in the recent quarter, compared with losses of $58 million, or 25 cents loss per share, in the year-earlier period. Analysts had expected the passenger airline to earn just $8.5 million, or 3 cents per share. "We are proud to have reported a profit in each quarter of 2009, one of only a few U.S. airlines to have done so," said Chief Executive Dave Barger. Last week Southwest Airlines and Continental Airlines each posted earnings that beat The Street's consensus call as the industry picks up steam. Delta Air Line s and United Airlines parent UAL each reported losses this week. (See " Airlines Beat The Street .")
