I’ve never heard a company announce a profit and sound so sad as US Airways did when they said that they were actually in the black yesterday. The bad news, though, is that they will not be profitable for the rest of the year, and they have deferred some regional jet orders. In addition, they will further scale back their Pittsburgh operation (even more than I mentioned a couple of days ago), and concentrate on point-to-point service from New York, Boston and Philly. They also will enter the miserably crowded and vicious NYC-Florida market, where fares start at $98 round trip. Their costs per seat mile are still nearly double those of JetBlue, and management is saying that $800 million still needs to be cut from employee wages and benefits. My suggestion: If you’re flying US Airways, take the miles on United.
